Problems solved by technology

However, this method only considers the improvement of the transmission and reception isolation between single antennas, and does not consider the array influence factor, and the measures adopted are relatively complicated, and it is difficult to realize the miniaturization and low-profile design of the antenna array
Therefore, these methods are difficult to be directly applied to the active phased array antenna array

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...

Abstract

The invention discloses a full-duplex active phased filter antenna array surface, and aims at providing an antenna array surface with high-isolation array transmitting and receiving and good filter characteristic. A transmitting antenna array surface of a transmitting array antenna and a receiving antenna array surface of a receiving array antenna consist of a plurality of arrayed radiation units;a multi-layer printed board integrally integrating a radiation circuit, a feed switching circuit and a filter circuit achieves connection between different circuits by vertical interconnection structures of metallized via holes; a metal upper cavity body of a transmitting-receiving component serves as a metal ground; a metal upper cavity body base of a metal floor is consubstantially connected byradio-frequency fuzz button connectors; and then a radiation unit and transmitting-receiving component integrated box-type submatrix module filter antenna unit is formed. With the adoption of the full-duplex active phased filter antenna array surface, high-isolation array transmitting and receiving can be achieved; insertion losses of array transmitting and receiving can be reduced; and high-precision amplitude and phase control can be achieved.

Description

technical field [0001] The invention belongs to the field of microwave and millimeter wave technology, and relates to a full-duplex active phased array antenna front face with filtering function for transmitting and receiving and filtering for electronic systems such as communication and radar. Background technique [0002] Full duplex (Full Duplex) is a term for communication transmission. Communication allows data to be transmitted simultaneously in two directions, which is equivalent to the combination of two simplex communication methods in capability. Full-duplex is a method in which the sending line and the receiving line are independent between the microprocessor and the peripheral device, so that data can be transmitted in two directions at the same time. It refers to the ability to receive data while sending data, and the two are carried out simultaneously. The phased array antenna refers to an antenna that changes the shape of the pattern by controlling the feedi...
