Design of rectangular micro strip patch antenna in geometrical shapes
Manish Kumar, Anuj Jain
The microstrip patch is one of the most preferred antenna structures for their light weight, low cost, low volume, low profile, smaller in dimension and ease of fabrication and therefore can be easily mounted on moving vehicles such as cars, planes, rockets, or satellites. Since its introduction in 1985, this antenna has led to an extensive amount of development and design variations by workers throughout the world. In this paper we present designs of compact small size microstrip antennas by loading properly arranged slots on a rectangular microstrip patch, dual and triple frequencies and broadband operations of a single feed rectangular patch is achieved. Dual and triple frequency operation is achieved by loading A and H slots in rectangular patch. The impedance bandwidth of 220MHz and 1.87 GHZ band for A slot and 154MHz, 396MHz, 484MHZ for H slot is obtained in the proposed designs.
