چکیده
Abstract: In this microstrip antenna design multi frequencies are used. Here working frequencies are 1.9 GHz and 2.0 GHz. Rectangular patch shape technique is used for designing this microstrip antenna. In our model electric field lines, conductance and input resistance have obtained by transmission line model whereas charge distribution, directivity and gains have brought by cavity model of rectangular patch. Correct feeds are applied at various positions and after comparing all the results the best of all will increase the efficiency and gain of microstrip patch antenna by 30-35%. All the results are mathematically calculated and achieved but these results may also be obtained by various designing software like Zeland IE3D software, Ansoft’s HFSS software and CST software.

متن کاملIntroduction and Overview 1.1 Introduction
Conventional microstrip antennas in general have a conducting patch printed on a grounded microwave substrate, and have the attractive features of low profile, light weight, easy fabrication, and conformability to mounting hosts [1]. However, mi-crostrip antennas inherently have a narrow bandwidth, and bandwidth enhancement is usually demanded for practical applications. In addition, applicatio...
