is excited with a

coaxial line. The normalized bandwidths of the input impedance

and Axial Ratio (AR) of the proposed antenna are found to be

17% and 13% respectively. Also, comparing the proposed

antenna with a similar structure...

. The results

show that at least 50 MHz of impedance bandwidth (S11 < -10dB)

at resonate frequency of 1.8 GHz is obtained. Also minimum

Axial Ratio (AR) bandwidth of 14 MHz is achieved. The

investigation shows radiation patterns...

This paper presents a novel method of increasing impedance and axial ratio (AR)

bandwidth of a single feed circularly polarized tip-truncated equilateral triangular microstrip

antenna (ETMSA). Tip-truncated ETMSA has been previously...
