Abstract

This paper describes a novel approach for the design of a compact microstrip loop antenna for 5.8 GHz ISM band applications. This antenna has been designed in a Flame Retardant (FR4) substrate which is placed above the ground plane with air dielectric. The resonant frequency of the proposed antenna depends on the radiating loop. A gap-coupled capacitive feeding mechanism, for achieving higher bandwidth is also studied. Full wave 3D simulation is carried out based on FDTD modeling technique. The designed antenna has been fabricated and the results obtained by experiments are found to be agreeing well with the simulation.
