Abstract—A new stub loaded equilateral triangular microstrip antenna(ETMSA) has been proposed . The new structure has the enhanced bandwidth of 13.63% in the Ku band.Stub loading technique is used to enhance the bandwidth performance. Two rectangular stubs are inserted on the radiating edge of the patch. The gain of the antenna is stable at about 5.78 dBi.Detailed analysis of the patch has been done in this paper using MOM based IE3D simulator.
Index Terms—Bandwidth enhancement,ETMSA,Secondary stub effect,STUB effect. ————————————————————
1 Introduction
Microstrip antenna are very popular in wireless communication systems due to their several advantages like low cost,thinprofile,light weight etc.,but on the other hand,microstrip antenna suffers due to its bandwidth problem [1].The most straightforward way to overcome the low bandwidth problem is to use the thicker substrate [2]. Unfortunately , the thick substrate results in impedance mismatch,large radiation loss [3] [4]. There are several techniques of Bandwidth enhancement processes. Lots of slotting mechanisms [5] i.e. wide
