Single-feed slotted antenna for triband applications

Abstract

In this paper, a tri band butterfly shaped Microstrip feed antenna for 3.852/5.773/8.341GHz application is presented here. The proposed microstrip-fed antenna forms operating frequencies by inserting one pair of slots on the ground plane with same lengths at a same distance from the center symmetrically. The size of the proposed antenna is 20×20 mm. The proposed antenna is simulated by ANSOFT designer var. 7 Software. In this antenna we use FR4 substrate with design specification dielectric constant (εr) of 4.4, thicknesses (h) of 1.6mm and its dielectric loss tangent is 0.02. Proposed antenna is useful for various wireless applications.
