Analysis of Single Slot on Microstrip Patch Antenna for Frequency Miniaturization

Abstract:

The design of microstrip patch antenna with a dimension of 27.1 mm  37.9 mm with single slots for miniaturization is presented. The antenna is designed on a FR4 dielectric substrate for 2.4 GHz. The antenna inserted with slot is designed to analyze the effect of surface current distribution and frequency miniaturization. The antenna with slots with variable length and width helps to achieve a frequency miniaturization of 30.41 % with reduced operating frequency of 1.67 GHz. The antenna has multiband operation covering major wireless bands with a maximum impedance bandwidth. The antenna exhibits good radiation characteristics gain. The antenna operates in the bands of WLAN, Bluetooth, GSM, ISM and GPS bands.
