Abstract
In this paper, a modified feeding structure for microstrip patch antenna is suggested for improving the performances. The proposed antenna has a gap between the transmission line and the recessed part of the radiating patch which makes a capacitive coupling. It shows higher 511(-l4dB) and lower cross polarization level(-2OdB) compare with the conventional inset ftd patch antenna while having a similar characteristics in another evaluating items. Experimental results are examined and considered to apply to the S-Band application, and the effectiveness has been confirmed by FDTD simulation and measurement simultaneously.
