ABSTRACT:
A diversity radio antenna includes a ground substrate and two elongated antenna elements. The antenna elements each extend between respective opposing ends thereof in a plane parallel to and spaced from the ground substrate. An excitation electrode is interposed between the respective ends. A ground connector switch is configured to selectively connect and disconnect the ground substrate to the antenna elements for controlling radiation beam pattern and polarisation diversity of the antenna. The ground connector switch is configured to selectively connect the antenna elements to the ground substrate for adapting the antenna to a circularly-polarised radio wave, or to disconnect one of the antenna elements from the ground substrate for adapting the antenna to a linearly-polarised radio wave.
