摘要
In this article, a novel compact UWB antenna with dual band-notched characteristics is proposed. The original UWB antenna is realized by etching an open-slot on the ground plane. The 5.2- and 5.8-GHz WLAN rejected bands are achieved by inserting a slot on the ground plane and a slot-type split ring resonator inside a circular exciting stub on the front side, respectively. The antenna has a compact structure with an area of 16 x 27 mm2. The small size makes it an excellent candidate for UWB operation. Prototype of the antenna are fabricated and tested. The simulated and measured results show that the proposed antenna achieves a wide impedance bandwidth (VSWR < 2) from 2.92 to over 12 GHz, and the dual rejected bands (VSWR > 2) are 4.855.37 GHz and 5.68-5.98 GHz. Radiation patterns and antenna gains are also given in this article. Detailed design steps, parametric studies and experimental results for the antenna are investigated in the following section.
