Summary:
This paper presents a design for a WLAN band rejection MIMO?UWB antenna The antenna consists of two coplanar waveguide fed monopole antennas with a pair of slots in the radiating patch that provides good rejection in the WLAN band. To enhance the isolation coefficient, a trident slot is etched into the ground plane. The main advantage of using the trident slot is that it possesses characteristics that are similar to single WLAN band rejection UWB antennas. The proposed antenna exhibits an isolation coefficient less than ?15 dB across the entire UWB band with a VSWR less than 3, and good rejection at the WLAN band. Additionally, the antenna has an omnidirectional radiation pattern within the UWB band.
