RF antennas play an important role in the communication signal transmission process as they transmit and receive information over the air or between two points. Among the most popular types of RF antennas are directional antennas, log-periodic antennas, omnidirectional antennas, slotted waveguides, and patch antennas. The W765FL-12-AM-AGDP is a type of patch antenna designed for the 12 GHz frequency band. This article will discuss the application field and working principle of the W765FL-12-AM-AGDP.

The W765FL-12-AM-AGDP is a multi-functional patch antenna that features both high horizontal and vertical beamwidths, a wide output power bandwidth, low sensitivity to horizontal and vertical movement, and high antenna gain. It is suitable for use in satellite communication, satellite earth station, antenna feeder radio road, digital TV, aeronautical communication, and navigation systems. The operating frequency range of the antenna is 11.7 GHz to 12.175 GHz, while its maximum output power is 400W. The antenna gain is 9.3±0.5 dBi, while its 3dB horizontal and vertical beamwidths are 90° and 60°, respectively.

The antenna consists of several elements including a reflector panel, a waveguide feeder, an antenna patch board, two phase controlling boards, and multiple screws. The antenna is rectangular in shape with a width of 850mm, a length of 795mm, and a thickness of 60mm. The input impedance of the antenna is 50Ω and the VSWR is 1.5:1. It also has a high cross-polarization discrimination of 30dB. The overall efficiency of the antenna is more than 89%.

The working principle of the W765FL-12-AM-AGDP is based on the reflection principle. The antenna is composed of a reflector panel and an array of antenna patches. The reflector panel reflects the incoming signals, which are then received by the antenna patch. The received signals are then converted to electrical signals for further use. In addition, the antenna features a two-board phase controlling system that enables users to adjust the radiation beamwidth. The two boards can be adjusted independently to meet the required multi-beam and angular coverage requirements.

The W765FL-12-AM-AGDP is a highly efficient patch antenna which can be used in a variety of applications. It is suitable for both high-power applications, such as satellite communication, as well as for low-power applications such as aeronautical communication and navigation. Its wide operating frequency range and high gain make it an ideal choice for many applications. Moreover, its adjustable two-board phase controlling system enables users to adjust the radiation beamwidth to meet the required multi-beam and angular coverage requirements.
