Embodiment 1

[0042] The heat dissipation scheme of the tile-type phased array antenna is divided according to the heat conduction direction, and there are usually two types:

[0043] One is the conduction of heat to the direction of the antenna. The design of this method is relatively simple, but because the heat conduction process will first pass through the microwave multilayer board or LTCC and then to the structural cavity, but the thermal conductivity of the microwave multilayer board is 0.4W / m.k, and the thermal conductivity of LTCC is 2W / m.k. Through holes can only improve its thermal conductivity, and large-area heat dissipation holes will affect the layout and wiring of multi-layer boards. The size and process requirements of local copper embedding are also very strict. This solution has a large thermal resistance from the chip to the heat dissipation surface. Excessive power and heat will accumulate in the microwave multi-layer board or LTCC under the chip and affect the performa...

Abstract

The invention discloses a high-power dual-frequency dual-polarization tile-type active phased array antenna. The wave control circuit layer accesses the dual-frequency signal, power supply and control signal, and transmits them to the rear layer; the feed network layer expands the channel of the low-frequency RF signal and transmits the high-frequency RF signal; the first RF layer and the second RF layer communicate with each other Cooperate with each radio frequency signal for radio frequency processing, and pass the processed signal of each channel to the array antenna layer, wherein the high frequency radio frequency signal is connected to the second radio frequency layer. Each channel output of the two polarized signals of the first radio frequency signal shares an antenna radiation unit two by two. The active phased array antenna designed in this design realizes the dual-frequency dual-polarization tile design, which has the characteristics of high power, miniaturization, and high integration.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a high-power, dual-frequency, dual-polarization, and highly integrated tile-type active phased array antenna. Background technique [0002] Active phased array antenna technology is widely used in military and civilian wireless communications, such as satellite communications, vehicle-mounted mobile communications, and terminal communications. At present, for complex communication scenarios, adding a dual-polarized antenna in a dual-frequency or multi-mode state can greatly improve the performance of the entire phased array antenna, such as anti-jamming and target recognition. More and more complex communication scenarios put forward higher requirements for high product integration, miniaturization, low cost, engineering manufacturing, testing and maintenance, etc. [0003] At present, most active phased array systems are brick-type, and tile-type active phased array antenn...
