Problems solved by technology

However, in view of the directionality requirement proposed in this paper, it is not common to expand the frequency band and have a strong directionality technology. In the general method of extending the frequency band, the dielectric board slotting or parasitic patch technology is often used. These technologies It can only solve the bandwidth requirements of the antenna, and its directivity is low

Abstract

There is provided a wideband patch antenna and an antenna array. The antenna includes a dielectric substrate of a rectangle shape, a radiation patch formed on a top surface of the dielectric substrate, a coupling patch formed on the top surface of the dielectric substrate and extending from a side of the dielectric substrate to a position from the radiation patch by a distance, a metal support arranged on the lower surface of the dielectric substrate and extending from the edge of the lower surface of the dielectric substrate downward to the ground, a layer of air having a predetermined thickness being formed between the lower surface of the dielectric substrate and the ground. According to the embodiments, it is possible to improve the directivity of the wideband microstrip antenna while maintaining its small size.

Description

technical field [0001] The present application relates to microstrip antennas, in particular to the technical field of broadband antennas. Background technique [0002] In millimeter-wave holographic imaging technology, in order to obtain a three-dimensional image of the measured target, it is necessary to obtain complete data information through frequency scanning with a certain bandwidth. In the scanning system, the transceiver antenna is located at the forefront, responsible for transmitting signals to the object under test and receiving the signal reflected from the object under test. The system integrated transceiver antenna has the following requirements: (1) Small size, easy to integrate with ; (2) Strong directivity, the direction of the main beam is facing the measured object; (3) Wide frequency band, meeting the system's requirements for frequency bandwidth. [0003] In the system integration, there are a series of requirements for the scanning transceiver antenna...
