Microstrip is probably the most successful and revolutionary antenna technology. Its success stems from very-well-known advantageous and distinctive properties, such as a low profile, light weight, planar structure, mechanical robustness, easy fabrication, easy integration of passive and active components, easy incorporation in arrays, and notable versatility in terms of electromagnetic characteristics. This communication presents a method to enhance the bandwidth of microstrip antenna by cutting a slot in the patch. Firstly, an antenna using inset microstrip line feed is designed for 5.2 GHz WLAN application. The bandwidth of antenna is found to be 170 MHz; which increases to 236 MHz when a rectangular slot is cut from the patch.
