Abstract

The invention belongs to the technical field of wide-beam antennas, and particularly provides a wide-beam stepped dielectric resonator antenna based on high-order mode superposition, which is used for solving the technical problems of narrow beam width, uneven upper half space gain and the like of the existing dielectric resonator. The wide-beam stepped dielectric resonator antenna specifically comprises a dielectric resonator 1, a floor 2, a feed slot 3, a dielectric substrate 4 and a feeder line 5, the antenna is fed by the feeder line, and electromagnetic wave energy is coupled and conducted to the dielectric resonator on the upper surface through the feed slot on the floor; and the dielectric resonator is a stepped dielectric resonator formed by sequentially adjoining first to seventh dielectric resonance units. Through the original design of the stepped dielectric resonator with symmetry, the antenna beam width is broadened by using a mode of superposing a pair of odd and even high-order mode radiation patterns of the dielectric resonator, the wide beam is realized, the antenna has excellent beam equalization, and the antenna is suitable for the application occasion of the wide-beam antenna.

Description

technical field [0001] The invention belongs to the technical field of wide-beam antennas, and in particular provides a wide-beam stepped dielectric resonator antenna based on high-order mode superposition. Background technique [0002] With the development of radar system and mobile communication system, the performance of antenna is very important, which seriously restricts the working performance of radar system and mobile communication system. Satellite communication small terminal antennas and aircraft antennas put forward higher requirements on the signal range of antennas, which promotes the research and development of wide beam antennas. [0003] So far, wide-beam antennas have mostly appeared in the form of microstrip antennas, magnetoelectric dipole antennas, and helical antennas; such traditional metal antennas will generate high surface wave loss and conductor loss when operating at high frequencies, resulting in The radiation efficiency is low, and the precisio...
