Nowadays, microstrip patch antennas are very popular in radar and satellite communication applications due to their low profile, mechanically robust, relatively compact and small size, and the possibility of dual frequency operation Unfortunately they have some limitations, especially narrow bandwidth. This paper presents a new high gain, wide band H-shaped slot loaded microstrip patch antenna. The antenna is printed on a dielectric substrate, supported by a metal plate, and fed directly from a 50 Ω coaxial cable. There are several and well known methods to increase the bandwidth of antennas such as: use of substrate thickness, low electrode substrate, various impedance matching and fading techniques In this paper, the bandwidth of rectangular Microstrip antenna is increased by ‘H’ shaped rectangular microstrip patch antenna. In some applications where increased bandwidth is required, dual frequency patch antennas are one of the alternative solutions. The proposed antenna has a dual frequency band.
