A novel high gain dual band ear bud shaped patch antenna for under water communications

Abstract

This article elucidates a high gain dual band ear bud shaped patch antenna with mm wave technology. The pivotal characteristic of this design is to provide higher gain and less interference at higher frequencies. It operates at a frequency of 40.59 and 52.002 GHz. The major advantage of this design is that it produces the circular polarization in entire band of frequency; moreover this antenna is useful for under water communication. The proposed design introduces two splits, imprinted at the walls of patch to get a wide band. For an optimal design, a future antenna parametric analysis was carried out. The proposed design is developed with the aid of HFSS software; we measured major parameters S11, VSWR, gain and radiation patterns in free space and underground environment. In the results, the predicted antenna radiation pattern is seen for E‐plane and H‐plane at various frequency bands. The gain 3D polar plots and current distribution plots are presented, including a comparison of previous work to the current work. We assure that the suggested design is applicable for under water communication.
