Embroidered Dual Band Wearable Microstrip Patch Antenna

Abstract

This research study presents an embroidered polyester-based dual band rectangular slotted wearable microstrip patch antenna for WLAN spectrum applications. To obtain the dual frequency bands, a slotted rectangular microstrip patch is coupled to an interdigital capacitor (IDC). The antenna exhibits a 4.97 GHz resonance frequency with a bandwidth of 100 MHz and a gain of 6.60 dBi. Additionally, this antenna has a gain of 7.85 dBi, a bandwidth of 390 MHz, and a resonance frequency of 5.59 GHz. The antenna has been constructed, tested, and the research paper's measurements show the outcomes. The results from simulation and measurement are discovered to be in good agreement. Additionally, a created and examined equivalent circuit of the antenna is presented in this paper.
