A packed small scale width circular in configuration aerial with WLAN and its Wi-Fi applications is proposed. Microstrip feed is used to make the design simple. To achieve impedance matching elliptical slots are created and notch in ground is made. Parametric analysis is done for better results. Return loss, bandwidth, gain, current density, gain and directivity are measured. Bandwidth achieved is 4.8 GHz from 7.6 – 2.8 GHz. Maximum gain of 4.24dB is achieved. CST Microwave Studio is used for simulation of the design. Patch radius is 7mm with dimensions as 18 * 37 (W*L).
