Abstract: In this paper we have presented a novel design and development of partial ground plane gap coupled corner truncated rectangular microstrip antenna (GCTRMA) for wideband application. The proposed antenna is simple in its geometry and can be constructed by splitting the rectangular monopole MSA along its width and then by truncating its corner part which act as parasitic patch element. This technique helps in getting the wide band operation of antenna. The antenna operates in the frequency band of 1.85GHz to 6.75 GHz and gives maximum impedance bandwidth of 113.8% and peak gain of 8.75 dB in its operating band. The antenna resonates at two frequencies viz., 3.64 and 4.79GHz and exhibits omni-directional radiation characteristics over the entire frequency band. This antenna is very compact and simple in the structure and can be realized using low cost glass epoxy substrate material and may find application in microwave communication systems.
