Abstract

The invention belongs to the technical field of active phased array radar and antennas. In order to solve the problems that the existing blind spot suppression techniques cannot suppress the scanningblind spots in a wide frequency range and the design difficulty increases due to the introduction of additional structures, the present invention provides a microstrip antenna unit comprising a dielectric plate and a feeding structure arranged on the dielectric plate, the feeding structure being used for suppressing scanning blind spots of the microstrip antenna array. By vertically arranging thesecond feeding structure in the dielectric plate, the surface wave of the microstrip antenna element can be effectively suppressed, thereby eliminating the scanning blind spots of the microstrip antenna array in a wide scanning range.

Description

technical field [0001] The invention belongs to the field of active phased array radar and antenna technology, and in particular relates to a microstrip antenna unit and a microstrip antenna. Background technique [0002] In active phased array radar, the antenna array is used to receive and transmit radio frequency signals. Through the control of amplitude and phase, while forming a specified beam, it can also scan the beam in space. Microstrip patch antennas have the advantages of low profile, light weight, simple structure, and easy design and processing. However, traditional microstrip antennas have narrow bandwidth and low radiation efficiency, which cannot meet the requirements of phased array systems for wide operating frequency bands. At the same time, the realization of functions such as active phased array fast beam agility and large-angle electronic scanning requires the antenna unit to have wide-angle scanning characteristics. However, since the microstrip anten...
