Abstract
This article proposes a miniaturized defective ground structure (DGS)-based microstrip patch that is suitable for usage in a variety of applications, including those in the medical, scientific, and industrial fields. The dimension of a conventional patch antenna at 2.7 GHz on an FR4 substrate consists of 11.01×5.19×0.1575 cm3, where the proposed antenna geometry is set as 5.89×3.06×0.1575 cm3, reducing the overall circuit size by 68.9%. This miniaturized antenna will be easily implementable in wearable devices for healthcare applications. The dimension and shape of the DGS are optimized in such a way as to improve the return loss from -19 dB to -24 dB at the desired frequency. Finally, the transmission coefficient for a conventional and suggested DGS-based antenna has been examined while these antennas are placed in a near-field region.
