Mechanically Stable No Adhesive Approach for Rectangular Dielectric Resonator Antenna: A Commercially Viable Design for Practical Applications

TLDR: In this article, a mechanically stable no-adhesive rectangular DRA with vertical metallic pins placed strategically on the ground plane has been explored as clipping devise to ensure robust fixation of DRA without any glue.

Abstract: This work demonstrates for the first time the possibility of realizing a mechanically stable no-adhesive rectangular DRA, which has been a long standing demand for practical implementation. A simple ground plane with vertical metallic pins positioned strategically have been explored as clipping devise to ensure robust fixation of DRA without any glue. The study is based on the dominant TE $_{11\delta }$ mode and the proposed design maintains unperturbed modal and the radiation characteristics throughout the band. The design has been executed for a 3.6 GHz antenna indicating its stability in maintaining the said characteristics. As much as 6 dBi gain with about 30 dB co to cross polar isolation has been demonstrated.
