Microstrip patch antennas are printed antennas that find suitability because they are lightweight, low volume, thin in profile, dual frequency, and dual polarization operation, and compatible with MMIC. The objective of chapter is to exhibit the investigations on the bandwidth enhancement of microstrip antennas with special reference to microstrip-line-fed wide-slot antennas. Performances are realized and validated through experimental studies on the impedance properties by VNA and radiation properties by pattern measurement setup. An innovative method for the design of hexagonal wide-slot antenna has been proposed considering it as an equivalent magnetic surface of monopole antenna. Impedance bandwidth of the above slot antenna is enhanced through various tuning stubs. In case of forklike tuning stub, the obtained bandwidth is about 900MHz, for hexagonal stub the available bandwidth is 1751MHz. Further improvement in bandwidth is proposed through rotation of hexagonal wide slot, results in wide bandwidth of 5165 MHz covering all the WLAN and WiMAX applications.
