Compact-size and Broadband Microstrip Patch U slot Antennas for C band Application and Stable Radiation Pattern overall band

Abstract

A wide band antenna using U slot and truncated ground plane antenna is presented, The antenna used four U slot at the reflecting patch and via hole is shorted in between radiating and reflecting patch of an antenna, the antenna is all four corner truncated and four U shape is printed on ground plane. The proposed antenna is suitable for C band applications and stable radiation pattern to overall band. The antenna is resonance at a band of 7.1 to 14  GHz. The VSWR bandwidth of the proposed antenna is 65.40% and achieved a directivity of 6 dBi and gain 3.9 dBi. The size of the of the antenna is 18.18x15.541x1.5 mm3. The antenna is suitable for Wimax, WLAN and other C band applications.
