摘要：
A wideband printed tapered-slot antenna with pattern reconfigurability is proposed. The antenna consists of four tapered slots, a reconfigurable microstrip-to-slotline transition, and four p-i-n diodes. With a suitable arrangement of bias voltages, four endfire radiation patterns are realized with a simple bias circuit. The measured relative impedance bandwidth of vertical bar S-11 vertical bar less than -10 dB is 71.3%, which is from 1.57 to 3.31 GHz in all operation modes. The gains for four directions are all higher than 6.4 dBi at the center frequency of 2.4 GHz. The measured and simulated results agree with each other well. The proposed antenna has good performances at four reconfigurable directions in a wide band.
