Elliptical Slot Antenna with Dual Band-Notched Characteristics for UWB Applications
关键词:
Dual band notched, elliptical slot antenna, UWB摘要
A novel elliptical slot antenna with bandnotched characteristics is presented for ultra-wideband (UWB) applications. The proposed antenna is fed via a microstrip-line that is connected to an elliptically shaped patch. Dual band-notched characteristic is achieved by utilizing an L-shaped strip and an inverted U-shaped slot incorporated within the antenna’s structure. This antenna configuration enables the notch band to be finely tuned by simply adjusting the parameters of notch function components, the L-shaped slot and the inverted Ushaped slot. The antenna with optimal parameters was fabricated on RT/Duroid 6006 that has a thickness of 1.27 mm and a relative permittivity of 6.15. The size of the actual antenna is 50×50 mm2 . The measured VSWR, gain, impedance and radiation characteristics of the proposed antenna confirm it satisfies UWB system requirements.
