Size reduction and bandwidth enhancement of aperture coupled based microstrip antenna by using Meander line slot

In this paper, a development of aperture coupled based microstrip antenna using meander line slot is presented. The proposed antenna constitutes of 2 substrate layers which are separated by a common ground plane. A Meander line slot is loaded to the antenna patch to reduce the dimension of the proposed antenna design. The antenna characteristics before and after applying a meander line slot are numerically investigated. Compared to the reference antenna design, using a meander line slot loaded to the antenna patch, it can achieves several performance improvements. These improvements are not only in terms of size reduction, but also in terms of bandwidth enhancement and antenna efficiency.
