Slot Loaded Dielectric Resonator Antenna for Bandwidth Enhancement

Dielectric Resonator Antenna,Microstrip antenna ,bandwidth , wireless communication

A Microstrip line feed, ground slot coupled dielectric
resonator antenna (DRA) is proposed in this paper.
To enhance the bandwidth of the dielectric resonator antenna,
embedding of the four rectangular slots have been proposed.
The proposed technique is simple and feasible. Using slots
loaded technique, 418% of bandwidth enhancement achieved
in simulated results. The effect of the slots dimensions on S11
and the gain of the DRA have been studied and presented.
The comparison of S11 characteristics of the antenna, with and
without embedding slots also presented in this paper. The antenna
design and optimization have been done using CST Microwave
studio 2016 software.
