摘要
A dual-notch ultra-wide band antenna is designed which consists of a U-shaped radiator bed by 50 ohms micro-strip. The defected ground structures have been adopted. A series resonant circuit is engraved in the feeder to achieve a notch in the 5.15GHz-5.85GHz band, parasitic strip structures are added on both sides of the feeder to implement another notch in the 3.3GHz-3.8GHz band. Simulation result shows that the U-shaped dual-notch antenna works stably at 2.4GHz-12.5GHz. It can effectively avoid the interference of both wireless local area network (5.15GHz-5.85 GHz) and the worldwide interoperability for microwave access (3.3-3.8GHz) frequency bands. Experiment result verified the design available.
