Analysis of different fixed and flexible dielectric materials on microstrip patch antenna for ISM band applications

Abstract

Recently, advancement in wearable technologies, one challenging improvement is textile antenna. The most requirements of textile antennas are dielectric materials which include fabric substrate and the structure of the antenna. The characteristics of the antenna depends on the substrate material. The dielectric value of the fabric material can be calculated from the operating frequency of patch antenna. In this paper the micro strip patch antenna is designed for ISM band applications. The main objective of this paper is to design and compare the performance of the micro strip patch antenna on different fixed and flexible dielectric material like FR-4, RT DUROID 6010, Polystyrene, Teflon, Quartz, Cotton, Alumina, Polyester with different constant in terms of gain, return loss, radiation patterns The proposed antenna operate at the resonant frequency 2.45GHz(ISM band) with low return loss and high gain and directivity.The size of the designed antenna has been also miniaturized.

Analysis of truncated structure flexible microstrip patch antenna on jute substrate for biomedical applications

“…The antenna's design and simulation were done using a jute substrate and 3.23 GHz as the operational frequency. Using a vector network analyser, the antenna is constructed and tested for the wetting, on-hand, and bending conditions [14]. Comparison in different substrate materials has been carried out in the literature work.…”
