Design of Wideband Directional Pattern Reconfigurable Circular Monopole Antenna
In this paper,a wide band,miniaturized directional pattern reconfigurable antenna is designed.Firstly,a mono-pole antenna with directional radiation characteristics is designed to change the radiation characteristics of the antenna by loading the diode and changing the working state of the diode.In order to ensure the broadband characteristics under different radiation states,the functional antenna with three beam deflection can meet the impedance matching characteristics in the full frequency band of 3 GHz～4 GHz.The simulation results show that the S11 of the antenna is less than-10 dB in the frequency band of 3 GHz～4 GHz,the maximum radiation direction gain is about 5 dBi,and the antenna has good radiation characteristics.
