An Integration of Planar Cavity-Backed Antenna with Artificial Magnetic Conductor in the Application of 2.4 GHz WBAN Application

Abstract

A high-gain array antenna is proposed using cavity-backed technology with the help of Substrate Integrated Waveguide Technology. The joint combination of both patch and the cavity-backed antenna is also known as a hybrid combination. Such types of antennas allow bandwidth enhancement and further division of patches to allow high gain and low cross-polarization behaviour. The whole patch antenna is further divided and based on the number of array elements in the patch, four array antenna cases have been proposed. A comprehensive investigation of them is presented. The proposed antenna operates at Ku-band, showing linearly polarized wave in TE101 mode and this hybrid combination provides several advantages. First, it has the advantages of a cavity-backed antenna and the conventional slot antenna. Second, an antenna is more compact. Third, it contains a much simpler matching network. In addition, being a member of the planner waveguide family, the proposed antenna also possesses a low profile and allows easy integration with the planner circuit. An exact representation of parameters of all antennas that have emerged during the designing course helps to grasp the sense of designing such kinds of hybrid array antenna of planner waveguide technology. Later, the proposed antenna is verified experimentally and exhibits a satisfying agreement with the data found during numerical simulation. The antennae’s simulated parameters were investigated with the help of CST (computer simulation technology) and HFSS (high frequency structure simulator) simulation software in microwave momentum mode.
