Pattern-Reconfigurable Antenna With Seven Switchable Beams in Elevation Plane

Le résumé fourni par la source

In this paper, a pattern-reconfigurable antenna is proposed that provides multiple switchable beams. By reconfiguring parasitic striplines placed around a radiating dipole and reflector under the dipole using p-i-n diodes, the antenna main beam can be switched to seven directions in the elevation plane, which are 0,30,55,120. The proposed antenna operates from 2.4Ghz to 2.5Ghz with dimensions of about 0.69λ×0.69 λ×0.69 λ. The prototype of the antenna was simulated and optimized in HFSS. For all directional beams, the simulated S11 values are below -10dB, and the simulated realized gains range from 7.5 to 8.3dBi.
