Abstract
A wide band Microstrip antenna with defected ground plane structure is proposed for Ku Band applications. The design procedure is presented and characteristics of the antenna are analyzed. A 50-ohm Microstrip line is used to excite the circular slot integrated in ground plane. The measured results demonstrate that the structure exhibits a wide impedance bandwidth of 56.67% ranging from 9.8 GHz to 17.55 GHz, which covers Ku-band and partially X-band. Within the band, stable radiation characteristics are observed. The designed antenna has a gain ranging from 5dBi to 12.1dBi in impedance bandwidth range. Isolation of about 20dB is observed between the co-polar and cross-polarization level.
