Abstract

Microstrip antenna is known as single patch which consists of simple dielectric substrate with ground plan that directly contacting an appropriate transmission line. Due to capacity problems in mobile communications system, microstrip patch antenna 1s proposed in order to minimize and solve this problem. This project was designed to investigate the performance of dual band and dual polarized microstrip patch antenna. A new design of a simple dual band and dual polarized microstrip patch antenna was presented with single feeding. Both ' Design 1 · and ' Design 2' was designed, fabricated and tested to be used in a dual frequency bands which is GSM900 and 1800 bands. The calculated results were confirmed by measurement on prototype. Both designs antenna can be operated at frequencies between range 924MHz-l 790MHz for simulation and for measurement 938MHz-1837MHz in antenna ' Design 1· . For antenna 'Design 2' frequencies can operate between 900MHz-I 760MHz for simulation and measurement between 904MHz-l 775MHz. Therefore, both dual band and dual polarized operation has successfully incorporated with single patch and feeding.
