Design and performance of two-sleeve low profile antenna for bio-medical applications

Abstract In this paper, a microstrip patch antenna is proposed which is suitable for bio-medical applications. The antenna is designed to operate in the Industrial, Scientific and Medical band at 2.45 GHz. Analysis of two sleeve microstrip patch antenna is presented using parametric variation. It is found that resonant frequency highly depends on sleeves dimensions. The performance of the antenna is analysed by comparing the measured and simulated results and found to be in good agreement with each other. The antenna characteristic impedance is 50 Ω and is fabricated on FR4 substrate. The simulation results are obtained on finite-difference time-domain based Empire XCcel simulator.
