Problems solved by technology

At present, the dielectric filter antenna unit is mainly realized based on a dielectric resonator, so the dielectric size is large and the profile is high; while the dielectric filter antenna array is realized by forming an array through the dielectric filter antenna unit, and there is no fusion of the filtering function for the array itself, which is not conducive to filtering Simplified structure of the antenna array

Abstract

The invention discloses a strip-type dielectric patch filter antenna array which comprises an H-type microstrip line and 1 * 2 strip-type dielectric patch filter antenna arrays. The H-type microstripline is used as a microstrip feed structure of the 1 * 2 strip-type dielectric patch filter antenna arrays. After a signal is fed into the H-shaped microstrip line through a coaxial line, the microstrip lines formed by the two metal strips parallel to the y axis in the H-shaped microstrip line are in half-wave distribution. Two strip-type dielectric patch antenna units working in the TM delta 1 mode are jointly coupled to symmetrical microstrip lines distributed in a half-wave mode, and 1 * 2 strip-type dielectric patch filter antenna arrays and the working frequency band thereof are formed. Use of a traditional power distribution network is avoided, and a TM delta 2 mode of the strip-type dielectric patch antenna units are utilized to form a high-end radiation zero point to improve frequency selectivity, so that reduction of the size and loss of the filtering antenna array, reduction of the profile and simplification of the structure are facilitated.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a strip type dielectric patch filter antenna array. Background technique [0002] Modern wireless communication systems are developing toward high integration, low power consumption, and miniaturization; the filter antenna has both filtering and radiation functions, which reduces the number of components, improves system integration, and reduces system loss and size. s concern. According to the type of radiator material, filter antennas can be divided into metal filter antennas and dielectric filter antennas. Compared with the metal filter antenna, the dielectric filter antenna has the advantages of low conductor loss and high degree of adjustment freedom, and is quite different from the metal filter antenna in the antenna working mode. [0003] Dielectric filter antennas are divided into dielectric filter antenna units and dielectric filter antenna arrays according to th...
