Best HUYUN Computer Networking Antennas in 2022

HUYUN Computer Networking Antennas

HUYUN computer networking antennas come with great features that make them ideal for internet connection. The regular poster antenna offers download and upload speeds of 3-5 Mbps, while the higher-end antenna can support up to 25 Mbps. The antenna box is complete and well-drawn, and it's built with a good client. Its tendency to transmit high-quality signal is an important factor, as it helps you to receive and send data fast.

SAR

A new type of SAR computer networking antenna is being developed by HUYUN. The HUYUN SAR antenna can cover a nominal access region with an incidence angle of 20 to 45 degrees. The design method for the SAR antenna mask template is proposed. Its advantages include fast convergence and better global searching capability. The antenna pattern synthesis algorithm is based on mask design method.

The proposed HUYUN SAR antenna can cover the following frequency bands: 2.4 GHz to 5.2 GHz. The proposed antenna has a dipole-like radiation pattern in the E-plane and omnidirectional radiation pattern in the H-plane. Its performance parameters are excellent and are based on the latest research. It also offers good radiation characteristics across operating frequency bands.

The SAR value is of great interest for designers. In COMSOL Multiphysics, the SAR value can be evaluated based on any shape and location. The RF Module makes the design process easy and fast. The HUYUN SAR Computer Networking Antenna comes with step-by-step documentation, including an MPH-file, to help you make the right design decisions.

The HUYUN SAR Computer Networking Antenne is made with a high-performance design and an impressive resolution of 300MHz. It also has a resolution of 1 meter, which makes it an excellent choice for long-distance computer networks. It is able to capture data from various base stations at the same time. In addition to a high-speed data transmission, the HUYUN SAR Computer Networking Antenna also features a powerful signal processor.

The HUYUN SAR Computer Networking Atenna uses a metal bezel and two sub antenna radiators. In the first region, the sub antenna radiator 'C' couples with the upper bezel part 213. However, the two antennas may be coupled without changing the Z-axis direction. The HUYUN SAR Computer Networking Antenna provides superior range of operation in both wireless and wired networks.

A reconfigurable ultra-wideband computer networking antenna employs three PIN diodes to achieve the notch band characteristic. The notch band is created by overlapping two U-shape and C-shape slots in the radiator patch and the additional patch on the ground plane. The proposed antenna reduces frequency interference between WLAN and UWB systems. Its compact size, excellent isolation and low envelope correlation coefficient make it ideal for such applications.

Effective length

The proposed HUYUN computer networking antennas possess superwide impedance bandwidth and a small amount of gain degradation under crumpling. This antenna is highly effective from 28 to 100 GHz. Besides, the antenna's voltage standing wave ratio is close to one. The radiation pattern of the antenna is good in both the E and H planes. The return loss curve of the antennas can be viewed in Table 3.

The impedance bandwidth of the antennas was close to that of free space. Its 60 GHz E and H plane radiation pattern was grained and the backward radiation was insignificant. This antenna's radiation efficiency varied from 76% to 81%, depending on the distance from phantom. It also covers the V and W bands. The antennas were tested at five different distances from the phantom. The closest distance to the phantom reduced the impedance bandwidth by about 10 GHz. The increase in the gap did not significantly affect the resonant frequency.

The antenna is made of polyester. It has different relative permittivity and thickness than other materials. Polyester has a higher permittivity than cotton and wool, which is why the antenna's effective length remains the same even after being stretched. Its design was further validated by using the CST microwave studio. Its effectiveness was determined by several tests. This paper discusses the design and analysis of HUYUN computer networking antennas.

Tilt and azimuth direction

HUYUN Computer Networking Antennos are designed to maximize the gain at the desired angle of inclination. Each antenna is adjustable in both the azimuth and tilt direction. The tilt controllers in the BTS provide the signal for each antenna to adjust its beam width and tilt. They are connected to the antennas through a packet switching network. The data received from the control network is used to calculate the adjustment. It then updates the adjustment log accordingly.

The EDX software enables users to specify the angle of beam tilt and azimuth direction, and the antennas can be adjusted accordingly. In the case of cellular base stations, the tilt and azimuth direction can be adjusted to match the cellular network configuration. The network performance is continuously monitored. Tilt and azimuth direction may change in case of unforeseen weather or other unforeseen circumstances, such as strong wind. High wind can move the pole to which the antenna is mounted, and the antenna itself may change its orientation.

Modified anechoic chambers

Anechoic chambers are specially designed to minimize echoes caused by radio waves. They are usually lined with a material that absorbs waves. Anechoic chambers are used for a variety of applications, including audio recording, radiated emissions, immunity testing, and antenna testing. In addition to measuring the performance of directional antennas, they are also used to test backhaul antennas. However, the design of anechoic chambers has its own challenges.

Typical anechoic chambers contain two layers of shielding material. This double layer of shielding provides the maximum shielding efficiency. A full-size semi anechoic chamber can cause mild heart palpitations. Engineers looking for alternative methods to a full-size anechoic chamber may find small shielded enclosures useful. These chambers allow for better testing of computer network antennas.

Anechoic chambers are a great way to simulate the outer space environment when testing antennas. An anechoic chamber is a tightly controlled environment where RF signals are not distorted. A computer-networking antenna under test is placed inside the chamber with a reference antenna and an identical receiver of known sensitivity. Various measurements are performed to determine how well an antenna performs.

Samsung Electronics uses several anechoic chambers to test radios. One such facility is located in the Digital City campus in Suwon, Korea. This chamber can simulate radio waves from hundreds of kilometers. In addition, it can also test mmWave antennas. High-capacity 5G mobile services use mmWave spectrum.
