A novel polarization reconfigurable aperture-coupled magneto-electric (ME) dipole antenna is presented. By electronically controlling the state of switches between square patches and an additional strip of the ME dipole, the antenna is capable of switching the polarization among one linearly polarized (LP) and two orthogonal circularly polarized (CP) states. An overlapped bandwidth of 16% from 5.07...
The paper proposes a new beam-switchable dipole antenna. The functionability is realized by reconfiguring the state of the four side apertures of a square substrate integrated waveguide (SIW). Four wide dipoles are loaded in front of the four apertures. The selected radiating aperture is able to excite the corresponding loaded dipole. The other dipoles work as reflectors. Thus, directional radiation...
