Abstract

This paper presented a slotted microstrip patch antenna working for two frequencies 1.42GHz and 2.65GHz respectively. Since a microstrip patch antenna works only on one resonant frequency so converting that into a multiband patch antenna would enhance the bandwidth use and also utilizes the multiple frequencies of operation. This multiband microstrip patch antenna is etched on FR4 lossy dielectric substrate whose dielectric constant is 4.3 and height is 1.6mm. The length and width of patch are taken as 51.16mm and 39.86mm. To convert the conventional microstrip patch antenna into multiband microstrip patch antenna we cut out the slots so that the patch antenna works at multiple frequencies. Simulation of micro strip patch antenna is done by CST software. Simulation and fabrication results show that the designed antenna characteristics are suitable for many applications.
