Ultra wide band dual stacked microstrip antenna with narrow slits

In this paper a Novel approach is presented to increase bandwidth up to 122.5 % with return loss less than -10 dBi in frequency range of 4.5 GHz to 18.7 GHz. Designed antenna is a stacked configuration which can also work for bands of frequencies, 19.413GHz to 19.937GHz ,2.99 GHz to 3.92 GHz and 461 MHz to 859 MHz. It provides promising gain which is maximum up to 7.8 dBi, antenna efficiency up to 98%. This antenna can work on various wireless standards and microwave bands. The various parameters like return loss, gain, radiation pattern and bandwidth have been studied and plotted for designed antenna.
