Corrugated Microstrip Patch Antenna for Bio-Medical Applications

This paper presents a corrugated micro strip structure for gain and directivity enhancement, required for stable, high-quality wireless communication in medical environments. Conventional patch antennas often suffer from limitations in gain when operating within Wi-4Fi frequency ranges, especially in complex indoor environments such as hospitals. The proposed antenna design is a gain-enhanced corrugated feed-edge micro strip patch antenna designed for medical Wi-Fi applications operating at a frequency of 5.3 GHz. This antenna optimizes all the performance metrics related to gain, directivity, and bandwidth. With a gain of 7.58 dB, the designed antenna shows very significant improvement in electromagnetic wave propagation compared to other conventional patch antennas. The efficiency of antenna maximizes due to optimization in electromagnetic wave propagation, hence promising robust connectivity in real time monitoring and data transfer of medical equipment. The designed antenna is evaluated in simulations and experiments, where results show an extensive gain improvement in comparison to standard patch antennas. The design perfectly fits tiny Wi-Fi devices developed for use within healthcare applications providing reliable wireless connectivity that will work continuously on limited interference with any other medical equipment being used.
