L-com Computer Networking Antennas For Embedded Use
L-com has recently announced a new line of computer networking antennas for embedded use. These new products support both 2.4.9 GHz operation, and feature integrated low-loss 1.13 mm coaxial leads that terminate with U.FL/IPX connectors. You can also order custom PCB antennas for special needs. Listed below are a few of the new products that L-com has to offer.
L-com's new 3.5 GHz small cell sector antenna
L-com has launched a new 3.5 GHz small cell sector antenna for cellular operators. With its compact form factor and four +-45 slant-polarization ports, the antenna offers professional quality and versatility for 3.5-GHz point-to-point and 4x4 MIMO applications. The antenna has a 65 degree beamwidth, is UV-resistant, and offers a high gain and low wind loading.
In addition to its omnidirectional design, the antenna offers greater RF performance and a wide range of capabilities. This antenna supports both existing LTE networks and future 5G deployments. It also supports public safety, railway, and utilities applications. L-com's new 3.5 GHz small cell sector antenna is designed to optimize RF performance and bandwidth while supporting existing LTE networks.
The new L-COM CBRS high performance sector HG3515SDP4-065 offers an extremely wide band, and provides industry-leading gain. It is compatible with a single 4x4 radio and two 2x2 radios. Its high front-to-back ratio and heavy-duty ABS radome add to its flexibility and performance. It is designed for both outdoor and indoor use.
A wideband antenna also features a low-visual-impact design, allowing for use in urban environments. Another feature of this antenna is its high port count. This enables it to support multiple operators and high data rates in many bands. It is compatible with several popular radios. It is also easy to install, so the new antenna will fit your mobile network. If you are interested in purchasing one of these 3.5 GHz small cell sector antennas, contact L-com for more information.
The newest L-com 3.5 GHz small cell sector antenna offers increased capacity and coverage in urban environments. With a compact size, the antenna is easily deployed on utility poles, lamp posts, and walls. The antennas are compatible with 2x2 MIMO and 4x4 MIMO and meet U-NII-1 requirements for gain. This antenna also offers enhanced coverage and reduced energy consumption, making it a good choice for urban and rural deployments.
These measurements were performed at six different locations. In each location, the antenna was installed behind a window. The path loss was measured until the connection dropped or the measurement reached the back side of the building. The measurements were also carried out outdoors on a rooftop terrace. These measurements show that the new antenna offers a significant improvement over existing 3.5 GHz small cell sector antennas. This antenna also enables indoor small cell networks to be installed in urban areas.
L-com's new 2.4 GHz spacial diversity/cross polarized sectorial panel antenna
Spatial diversity is a radio technology that combines two or more omnidirectional antennas to increase signal strength, minimize fading, and eliminate blind spots. Spatial diversity is the only radio technology to be effective in both 2.4 GHz and 5 GHz frequencies. It can be applied to both cellular and Wi-Fi networks. Spatial diversity allows for a more efficient use of space, while cross polarization is best suited for outdoor applications.
L-com's new 2.4 GHZ spatial diversity/cross polarized sectorial panels are an outdoor, all-weather, and omnidirectional antenna designed for outdoor use. The antennas are fed through four connectors and feature two identical cross polarized elements inside. The resulting radiated wave is left-handed circular.
The measured results were compared to the simulated results using an AMS-8050 Antenna Measurement System by ETS-LINDGREN. Figure 23 shows the measurement set-up of a non-transparent antenna in a chamber. Simulated and measured gains are quite similar at the target operating frequency. One discrepancy exists with the transparent prototype, however. This is due to the fact that the transparent conductive fabric is thin and therefore more susceptible to damage during cutting.
In some cases, spatial diversity is necessary for co-located wireless systems. When more than one antenna is installed in the same facility, the interference caused by each antenna can be exacerbated. Using a 45-degree slanted cross polarized antenna can mitigate such problems and increase performance. Spatial diversity can also be applied to some L-com antennas, allowing them to perform better in multipath environments.
A multi-faceted design, the 2.4 GHz spacial diversity/cross-polarized sectorial panel antenna is a hybrid antenna with two monopoles that exhibit a wide radiation bandwidth. The antennas are mounted on a printed circuit board and the board serves as a ground plane. A single monopole antenna is mounted on the zenith and a monopole antenna is disposed on the other. The resulting hemispherical coverage pattern is called a switched hemispherical radiation pattern diversity antenna. In addition, the antennas are oriented perpendicularly to the printed circuit board, resulting in a donut pattern.
The SAR is calculated by considering different separations. The SAR is calculated by applying 0.1 W of input power to a 10-g tissue sample. In addition to the SAR, the antenna's radiation efficiency and peak gain have been analyzed. The results are presented in Figure 15 and Figure 16.
The antenna is fabricated in a manner that minimizes fabrication tolerances. The 10-dB return-loss bandwidth of both antennas is around 346 MHz. However, some differences may occur in the antenna's impedance matching due to phantom proximity or bending. However, despite the potential for resonance, both antennas operate satisfactorily in the frequency bands.
L-com's new 2.4 GHz small cell sector antenna
L-com has released its new 3.5 GHz small cell sector antenna with a compact form factor and integrated N-female connectors. It supports MIMO (multiple input multiple output) applications and features a 15-dBi gain. Designed for outdoor deployment, the new antenna is capable of withstanding speeds up to 100 mph and a wide range of harsh conditions.
L-com's 180-degree MIMO sector antennas are the latest addition to the company's extensive portfolio of wireless connectivity products. The HG2458-13P-180 features dual-band support and high-gain sensitivity. It also features patent-pending technology that allows it to support 2.4 and 5 GHz frequencies. The 2.4-GHz antennas cover a broad range of frequencies, including UHF, VHF, and GSM, and can also be used for cellular and other Wi-Fi networks.
Antenna configurations include conventional parabolic and slot radiating designs. Optical fibers and slot radiating designs are among the options. The antennas can be designed and tested using MATLAB toolboxes. It is also possible to choose a combination of antenna configurations, including flat panel micro strip antennas, slot radiating antennas, and traditional parabolic-style designs.
The HG909YE-NF-BLK is a dual-band antenna with Type-N connectors. It features nine dBi gain and supports 824 to 960 MHz frequencies. The HG2458-10DP-BLK has a black anodized aluminum boom, is ideal for outdoor and indoor installations, and is aimed at point-to-multipoint (P2MP) applications. And the HG2403RDR-MMCX has a flexible design and operates in the 2.4-2GHz frequency band.
RF coverage simulations with an eight-by-16 array of stacked sector antennas showed improved coverage and RF signal strength when compared to single-element arrays. In addition, the amplitude-tapering antennas reduced the peak power of sidelobes by 1.73 dBi and reduced interferences by 2.5%, respectively. The 16-by-16 sector antennas, in particular, have the highest average SINR, which is perfect for small cell deployment.
The outdoor 2.4GHz sector antenna is perfect for Internet Locations with limited coverage or that are in the corner. It will not waste wireless coverage, but it should be used in situations where Line-of-Sight is required. The 17dBi antenna comes with mounting hardware and basic technical support. In addition, it can be mounted in pairs or sets of three to provide 180-degree coverage, or used alone for coverage of 90-deg.
The BS antenna' height also affects RF coverage. In Figure 25b, RF coverage results with different antenna heights. As you can see, the RF coverage decreases from 25 m to 15 m. The situation improves slightly once the antenna is elevated to 35 m, but it is not quite as good as it was at 25 m. This BS antenna is capable of increasing the RF signal strength up to a maximum of 65 dB despite heavy fog.
