Compact Uwb Bandnotch Antenna with Transmission-line-fed

In this paper, a compact band-notched UWB planar antenna with Transmission-Line-fed is presented and I’m using a new technique by etching a narrowband resonance H-shape slot in the ground plane of the antenna. This antenna is capable reducing the interference at the WLAN bands by eliminating the 4.85–6.17 GHz band. The proposed antenna has compact size of 16 × 22 mm2 including the ground plane and because of miniature dimensions, good radiation patterns with monopolar characteristics are obtained in the frequency band of interest i.e., at least 10 dB isolation exists between co-polarization and cross-polarization. The gain is suppressed very well in WLAN bands. The maximum suppression is in 5.4 GHz that is 13.6 dB less than the gain of normal antenna.
