Half-wave stacked patch antenna with dielectric feed
Veli Voipio, Jani Ollikainen, P. Vainikainen · 2003
A half-wave stacked patch antenna was developed for sufficient bandwidth and cross-polarization separation for the wideband radio channel sounding. To further reduce the cross-polar level, a concept of dielectric feed was developed, which electromagnetically resembles the aperture feed. The increase of the cross-polar discrimination was 2.6 dB in the prototype.
