Abstract: In wireless communication era, we need the antennas with low profile, light weight, planar but can meet the characteristics of non-planar structures, with ease of fabrication, flexibility in terms of electromagnetic parameters like radiation pattern, gain, impedance, polarization etc. Microstrip patch antennas, which come at low cost, size, good performance, ease of installation and easy integration to circuits, high efficiency, are suitable in that context. The Principle of slot is used on the patch which decreases the radius of the circular patch antenna, so as to reduce the size. In this work various Ircular microstrip patch antenna arrays are intended for the application of WLAN and Wi-Max at 2.4GHz for the improvement of gain. Single microstrip patch antenna and planar arrays of 1×2 and 2×2 ircular microstrip patch antennas are designed using strip line feeding technique and simulated on FR4 substrate. The planar antenna arrays are simulated using the High Frequency Structure Simulator (HFSS) software version v17.2 and the parameters like gain, return loss, Bandwidth and VSWR are evaluated at 2.4GHz frequency and the same are presented.
