Abstract

The invention discloses a compact dual-pass band circularly polarized dielectric resonator antenna with differential embedded feeding, which solves the lack of a dual-pass band circularly polarized dielectric resonator based on a differential system with excellent performance and size in the prior art The technical problem of the antenna, the antenna includes: a dielectric substrate (10); a dielectric resonator (30) arranged on the surface of the dielectric substrate (10); first and second arc strips embedded in the dielectric resonator (30) Strips (41, 42) and first and second coaxial probes (51, 52); one end of the first coaxial probe (51) is connected to the first arc strip (41), and the other end is connected to the first The differential port (61) is connected, one end of the second coaxial probe (52) is connected to the second arc strip (42), and the other end is connected to the second differential port (62). This solution has independent and controllable characteristics, greatly simplifies the design process of the dual-pass band circularly polarized dielectric resonator antenna, and realizes the compact design of the antenna at the same time.

Description

technical field [0001] The invention relates to the technical field of radio frequency communication, in particular to a compact dual-pass circularly polarized dielectric resonator antenna with differential embedded feed. Background technique [0002] Radio frequency microwave antenna is an indispensable transceiver component of wireless communication system, and dielectric antenna has compact structure, good consistency, low cost and high efficiency, and has been greatly developed in recent years. Circularly polarized antennas and dual passband antennas are two antenna forms of dielectric antennas. [0003] Specifically, circularly polarized antennas are widely used in contemporary satellite and mobile phone communication systems because they can effectively overcome the multipath effect and polarization mismatch between antenna signal transmissions. In addition, in order to further pursue the compact design of the system, dual passband antennas have been proposed and wide...
