Band-Stop Antenna with Enhanced Bandwidth by Using Several Pairs of Inverted L-Shaped Sleeves on the Ground for Wireless Applications
Keywords:
Antenna, stop band, UWB, very wide bandAbstract
A very wideband rectangular monopole antenna with band notched performance for wireless applications is proposed. The very wideband performance is obtained by introducing a new technique on the ground plane including several pairs of inverted L-shaped sleeves which provide a very wide bandwidth. By utilizing two radiating stubs in which an inverted ?-shaped strip is protruded, band-notched characteristics can be obtained. The measured results exhibit that the antenna is able to covers the bandwidth from 2.5 to 17.5 GHz, excluding the rejected bands from 3.1 to 4 GHz and from 5 to 6 GHz.
