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.

A diversity radio antenna, comprising a ground substrate , first and second elongated antenna elements, each extending between respective first and second opposing ends thereof in a plane parallel to and spaced from the ground substrate, and an excitation electrode interposed between said respective first ends, each antenna element having one grounding point connectable to the ground substrate, wherein the first antenna element has a first ground connector switch means selectively connecting or disconnecting the first antenna grounding point to the ground substrate, and the second antenna element has a second ground connector switch means selectively connecting or disconnecting the second antenna grounding point to the ground substrate, wherein said ground connector switch means are configured to selectively connect one or both of said antenna elements to said ground substrate for controlling radiation beam pattern and polarisation diversity of the antenna.
A radio communication terminal comprising a diversity radio antenna, the diversity radio antenna comprising:
- a ground substrate, first and second elongated antenna elements, each extending between respective first and second opposing ends thereof in a plane parallel to and spaced from the ground substrate, and an excitation electrode interposed between said respective first ends, each antenna element having one grounding point connectable to the ground substrate, wherein the first antenna element has a first ground connector switch means selectively connecting or disconnecting the first antenna grounding point to ground, and the second antenna element has a second ground connector switch means selectively connecting or disconnecting the second antenna grounding point to ground, wherein said ground connector switch means are configured to selectively connect one or both of said antenna elements to said ground substrate for controlling radiation beam pattern and polarisation diversity of the antenna.
