陷波可重构的超宽带缝隙天线设计
Design of UWB Slot Antenna with Reconfigurable Band-notch Characteristics
摘要
Abstract
A ultra-wideband (UWB) slot antenna with reconfigurable band-notch characteristics is presented in this paper..A hexagonal slot and a tapered-shape microstrip feed-line with a rectangular radiating stub are employed to realize the UWB operation.The band-notch function in WiMAX and WLAN band is obtained by placing an inverted L-shaped parasitic structure beside the feed-line and etching an inverted U-shaped slot on the rectangular stub, respectively.The switches are loaded in the parasitic structure and inverted U-shaped slot, and then the reconfigurable band-notch capability is achieved by changing the combination states of control switches.The overall size of the antenna is 24.5mm×20.5mm.The simulated and measured results show that the antenna can operate in UWB, two single band-notch and a dual band-notch modes.关键词
