An integrated UWB and bluetooth antenna with dual WLAN band-notched

A small-size, low-profile, and planar integrated antenna is presented. This antenna is fed by a microstrip line and built on a PTFE substrate with only 20mm*46mm and the overall size of the radiating element is 15mm*16mm. A semicircular slot resonator and a split ring slot resonator are embedded in the radiating patch. The bandwidth of this antenna is 2.25-11.25GHz which covers UWB (IEEE 802.15.3a, 3.1-10.6GHz) and Bluetooth (IEEE 802.15.1, 2.4-2.484GHz), but with dual WLAN band-notched of 4.96-5.29 GHz and 5.54-6.01 GHz.
