Abstract

The invention discloses a miniaturized waveguide power division network, which is composed of at least two one-into-many waveguide power dividers adopting a double-layer waveguide structure. Each one-into-many waveguide power divider includes a first layer of waveguide structure, a second layer of waveguide structure and at least one first-type transition mechanism, and the first-type transition mechanism is provided with a first height transition part and a second height transition part which are in transition connection with the first layer of waveguide structure and the second layer of waveguide structure respectively so that the first layer of waveguide structure and the second layer of waveguide structure are in planes at different heights. The advantages are as follows: because the waveguide power dividers adopting a double-layer waveguide structure are placed alternately, the space is fully utilized, and the volume of the device is reduced; and for a large phased array feed network, a miniaturized waveguide power division network is realized and the demand of the modern phased array technology for a miniaturized feed network is satisfied under the premise of ensuring excellent isolation of the output port and easy integration of the output port with the circuit.

Description

technical field [0001] The invention relates to the field of microwave devices, in particular to a miniaturized waveguide power distribution network used for power distribution and calibration feed networks of phased array antennas. Background technique [0002] In recent years, with the rapid development of phased array technology, the application fields have become more and more extensive, and more stringent requirements have been put forward for its volume and weight. Therefore, the miniaturization requirements for the phased array feed and internal calibration network are getting higher and higher. In addition, the anti-interference performance requirements of modern radars are getting higher and higher, and the antenna sidelobes are required to be lower and lower, and the bandwidth is wider and wider. In order to meet such a low antenna sidelobe and such a wide bandwidth, higher precision requirements are put forward for the bandwidth, amplitude and phase of the phased...
