Abstract :
The design and analysis of a series-fed, low-loss, inverted microstrip array antenna, operating at 1.413 GHz is presented. The array antenna is composed of two subarrays consisting of an equal number of microstrip patches connected together through a series microstrip line. The subarrays are coaxially fed 180° out of phase. This approach ensures a symmetric radiation pattern. The design approach for obtaining a low sidelobe ratio and a low loss microstrip array is accomplished using the IE3D code. Experimental and simulated data are presented and discussed.
