Miniature broadband antenna for WLAIM/WiMAX and lower-band UWB applications

摘要

A miniature broadband antenna is presented for applications in WLAN, WiMAX and lower-band UWB. This triple-mode antenna consists of a multi-branch radiator with overall dimensions of only 10(L) × 10(W) × 0.8(H)mm~3 to be embedded in a portable device and with a wide operating band covering 2.4 to 6.8 GHz. Simulated and measured results are compared, which show good agreement. Also, suitable group delay and transmission characteristics can be achieved in the UWB lower band.
