Abstract:
A novel compact strip-line fed UWB antenna with band-notched characteristic is proposed. By employing a balanced antipodal structure and strip-line feed, the size of this antenna has been reduced to only 23 mm×27.5 mm with the dielectric substrate of relative permittivity 2.65. Meanwhile, a slot is added onto the radiating patch of the mid metalisation layer to realize the band-notched function, by tuning the length of which suitable rejected frequency band can be obtained. According to the measured results, the proposed antenna has a large bandwidth totally satisfying the requirement of UWB applications (3.1~10.6 GHz) with good stable omnidirectional radiation patterns and gains except in the rejected frequency band (4.9~6.2 GHz). Details of this antenna are described, and the experimental results of the constructed prototype are given, too.
