Abstract :
A low-profile orthogonally linearly tripolarized antenna consisting of two thick-slot antennas and one half-mode substrate integrated waveguide (HMSIW) antenna has been investigated. The two thick-slot antennas radiate x- and y-directional linearly polarized waves, while the HMSIW antenna contributes to the z-directional polarized wave. The low-profile geometry is achieved by utilizing the HMSIW antenna. Isolations between the three antennas measured are lower than -20 dB, which means that the proposed antenna geometry provides good diversity gain and the channel capacity can be increased by as much as three times.
