Compact Band-Notched Ultrawideband Antenna With Entire 5-GHz WLAN Band Rejection
A compact ultrawideband (UWB) monopolelike slot antenna having band-notched characteristics over entire 5-GHz wireless local area network (WLAN) band is presented. The proposed antenna comprises a coplanar waveguide (CPW) fed monopole-like slot and band-notched structures. By adding grounded open-circuited stubs in the slot and embedding spur-lines in the fork-shaped feeding structure, the notched-frequency /bandwidth are controllable. A compact antenna prototype which is etched onto an FR4 printed circuit board (PCB) with an overall size of 26 mm× 29 mm× 1.5 mm demonstrates good impedance matching, constant gain, stable radiation patterns over an operating bandwidth of 2.6 - 13.0 GHz except the 5-GHz WLAN band of 5.15 - 5.85 GHz, where sharp and high band rejection is achieved.
