Embodiment Construction
[0025] refer to Figure 1-Figure 4 . In a preferred embodiment described below, a full-duplex active phased array filter antenna front includes, based on the sub-array extension technology, a transmit array antenna that is divided into multiple sub-arrays according to the coordinates of the front 1, the sub-array It is a receiving array antenna 2 of multiple sub-arrays and a high-resistance surface isolation structure 3 . The transmitting antenna front of the transmitting array antenna 1 and the receiving antenna front of the receiving array antenna 2 are composed of many radiating elements arranged in an array; The printed board 4 uses the vertical interconnection structure 13 of the metallized via hole to realize the connection between different circuits, and uses the metal upper cavity 5 of the transceiver assembly as the metal ground, and connects the metal ground of the metal floor through the radio frequency button connector 15. The base of the cavity 5 is connected wi...
