Abstract

In this paper, a multi-band multi-mode hybrid antenna using a liquid Dielectric Resonator Antenna (DRA) and patch configuration working for Wi-Fi applications at 2.4 GHz and 5 GHz bands is designed. This work proposes a way to suppress and replace undesirable higher-order modes of the DRA with desirable modes using a hybrid design keeping the compactness of the antenna still intact. The result is a compact multi-mode antenna with dimensions ≤1/2 λ0 (length & width) and a height ≤1/4 λ0, overall 0.42λ0× 0.42λ0× 0.18λ0 , (' λ0 ' is the wavelength at 2.4 GHz) with decent radiation efficiency, total efficiency, and realized gain for both lower and higher order modes.
