Abstract

The narrow bandwidth of microstrip antenna is one of the important features that restrict its wide usage. This paper presents a bandwidth enhancement using slot geometry for the feed line matching is proposed and experimentally studied. The maximum bandwidth can be achieved by keeping the optimum distance between the two slots and by adjusting the length of the transmission feed line 50 Ohm. Return loss of -77.74 dB with VSWR 1.0026 for frequency at 940 MHz. The results show that the proposed antenna has the i m p r o v e d impedance bandwidth covering whole band.
