Problems solved by technology

However, as the number of layers of the radiation sheet increases, the materials used for the radiation sheet and the base material increase, the processing cost becomes higher, and the volume and quality of the antenna also increase.
However, if only one layer of radiator is used, the working bandwidth of the antenna is narrow

Abstract

The invention relates to a microstrip patch phased array antenna unit and a microstrip phased array, the antenna unit comprises a grounding substrate and a layer of conductor patch, and the conductor patch is laid on the grounding substrate; steps are arranged on the opposite angles of the conductor patch, and the conductor patch forms a plurality of different resonance circuits through the steps. The antenna unit can be tuned in a plurality of different frequency bands respectively to form a plurality of different resonant circuits and has a plurality of different resonant frequencies, so that the frequency band width of the antenna is broadened, and the antenna unit can save the materials of patches and base materials and reduce the material cost.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a microstrip patch phased array antenna unit. Background technique [0002] Microstrip patch phased array antenna can be divided into horizontally integrated tile structure and vertically integrated brick structure according to the integration method. Among them, the tile-type phased array antenna has the characteristics of low weight, small size, and easy integration with the platform. The tile structure uses a multi-layer architecture to integrate and connect the radio frequency, control signal and power supply through vertical interconnection technology. The tile structure has become the mainstream of today's phased array antenna development. [0003] The tile-type phased array antenna unit generally adopts a multi-layer radiation patch unit, and the base material is filled between each two layers of radiation pieces, and the multi-layer radiation piece can expand the workin...
