The proposed antenna is tested using VNA E5071C.As a result it can be also observed in being when the size of ground plane is increased, the ripples in the main pattern diminishes. In this observation, the paper calls for an attention that, the cachet is an amelioration of the 2.4 GHz Industrial, Scientific and Medical (ISM) Band patch antenna is simulated and analysed using HFSS 13.0 and fabricated by photo lithography. These antennas are suitable for WLAN Applications. The design was optimized to obtain the most suitable configuration in terms of desired values of reflection coefficient, bandwidth and Voltage Standing Wave Ratio (VSWR) for antenna with and without modifying on ground plane. The patch antenna is provided by inset feed line. The substrate used is Flame Retardant-4epoxy having dielectric constant of 4.4 and dielectric tangent loss of 0.02. The finite ground plane gives rise to diffraction of radiation from the edges of ground plane resulting in modifying of radiation conductance, radiation pattern, and resonant frequency. short edge, double ground, triple ground in terms of Bandwidth, Gain, Directivity, VSWR, Reflection coefficient and efficiency performance. This paper is concentrated on comparison of rectangular patch antenna with different ground plane dimensions i.e.
