This paper focuses on Coplanar Wave guide (CPW)-fed wide-band microstrip antenna which best suites for wireless applications. In order to optimize the size of microstrip antenna, the substrate is taken in the form of structure-shape. The rectangular substrate is etched in the form of semi-circular disc to attain this structure shape. An inverted L-strip radiating patch is mounted over the semi-circular disc substrate. The overall size of antenna is 22mm × 22mm × 0.77mm. The proposed antenna has gain of 2.73dB, and exhibits parameters such as efficient group delay, perfect radiation patterns with acceptable impedance bandwidth of 100.7% at 6.85 GHz centre frequency and covers the entire operating bandwidth of range 3.4 to 10.3 GHz. High Frequency Structure simulator (HFSS) software is used for designing and simulation of CPW-fed microstrip antenna. The designed antenna is used in various c band applications.
