Abstract
The design and analysis of a new three-stacked patch antenna on aluminum oxide ceramic material substrate are presented in this article. Using high-dielectric material substrate, the overall size of the antenna is appreciably reduced without compromising the performance result of the antenna. The proposed antenna is designed and studied using commercially available finite element method-based high-frequency electromagnetic solver from ANSYS Corporation. From the result, it is observed that in the operating frequency range from 16.20 to 19.31 GHz (voltage standing wave ratio < 2), a wide range of bandwidth of 3.09 GHz and gain of 7.05 dBi at a resonant frequency of 17.20 GHz is achieved. It is also found that at the entire operating frequency band, the average gain is 3.5 dBi and the radiation efficiency is from 84% to 89%. The proposed antenna is fit for part of Ku-band and Ka-band applications.
