A Novel Hexagonal Slotted Circular Patch Antenna for ISM Band Biomedical Applications

In this work a novel hexagonal slotted circular patch antenna is developed. The antenna is developed to be operating in ISM band $(5.72-5.87\mathrm{GHz})$ for biomedical applications with center frequency of 5.8 GHz. The designed antenna shows the simulated and measured -10dB band width of 180MHz(5.71- 5.89GHz) and 760MHz (5.4-6.16 GHz) respectively, which covers the entire 5.8GHz ISM band. The simulated gain and efficiency of designed antenna are 4.85 dBi and 97% respectively at resonance frequency of 5.8 GHz. The experimental results of developed antenna show the good agreement for ISM band biomedical applications.
