Broadband-Filled Dielectric Resonator Antenna Based on LCP Suspended Coplanar Waveguide

Abstract

In this report, a self-packaged millimeter wave filled dielectric resonator antenna (DRA) is presented, which is based on polymer liquid crystal polymer (LCP) multilayer suspended coplanar waveguide (CPW) structure. By filling the dielectric resonator in the substrate, our design provides a new way to fix the dielectric resonator antenna. Meanwhile, the dielectric resonators filled in the substrate form a stacking form with the lower substrate, which can excite more modes and expand the antenna bandwidth. The antenna adopts the form of coplanar waveguide slot fed dielectric resonator for mixed radiation. The center frequency of the antenna is 47.85GHz, the relative bandwidth is 31%, and the maximum gain is 8.8dB.
