Abstract

The invention discloses a transceiving common-caliber phased array antenna. The antenna comprises a PCB multilayer board, the front surface of the PCB multilayer board is an antenna unit, a feed network and a welding multifunctional multi-channel chip are arranged on the back surface, the rest middle layers are radio frequency signals, chip feeding and control wiring, a plurality of transceiving dual-frequency antennas are arranged on the PCB multilayer board in an array manner, a transmitting single-frequency antenna is arranged in the middle of the plurality of transmitting-receiving double-frequency antennas on the PCB multilayer board, radio frequency transmitting antennas are arranged on the upper layers of the plurality of transceiving double-frequency antennas, and the PCB multilayer board is provided with an isolation cavity structure for isolating the transceiving double-frequency antennas and a transmitting single-frequency antenna. By means of the mode, the phased array antenna can solve the problem that a traditional satellite communication antenna cannot have the advantages of being low in profile, low in cost, easy to integrate, light in size and weight and rapid in beam scanning.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a phased array antenna with common aperture for transmitting and receiving. Background technique [0002] Wireless communication is one of the most important means of communication today, especially in the rapid development of satellite communication this year, the requirements for satellite communication terminals are getting higher and higher. Traditional satellite communication terminal antennas include parabolic antennas, VICTS (variable inclination continuous section Section) antenna, sending and receiving sub-aperture phased array antenna. The parabolic antenna is a common-aperture antenna with integrated transceivers. The beam scanning is realized by mechanical servo. The parabolic antenna itself is large in size, and the additional mechanical structure of the servo increases its volume and weight. It is not easy to integrate on various platforms, especially for volum...
