Design of Miniaturized Printed Antenna for Medical Applications

Abstract

This paper introduces the design, simulation, implementation of miniaturized printed minder line monopole antenna (PMLMA) in medical application. The proposed antenna operates in Industrial, Scientific, and Medical ISM band. Antenna has a compact size of (12.25×7.81×0.8) mm3 with -10 return loss printed on FR4 substrate material with (4.3) dielectric constant and h (0.8) thickness . The proposed antenna is simulated and evaluated using CST microwave studio package. The propose antenna simulation result obtain that antenna operate on 915MHz frequency with less than -10dB return loss (-11.237)dB , gain is -18.23dB, band width 20.546MHz and total efficiency -20.64dB. Results of simulation and implementation show that the proposed antenna possesses an acceptable performances and miniaturized dimensions, enabling their use in medical applications.
