摘要: A compact Ultra-Wide Band (UWB) antenna with sharp band-notched characteristic and controllable notched bandwidth is presented. The band-rejected structure realized by inserting two half wavelength C-shaped slots the same resonant frequency in radiator. couple together to form a band rejection. good impedance matching obtained 3.1–10.6 GHz range(|S11|<−10 dB), except lower WLAN of 5.15–5.35 (|S11| >−5 dB). Moreover, can be controlled adjusting dimensions slots.
