Abstract
An antenna array structure is described that includes at least two antenna arrays co-located on a common planar array reflector. One of the antenna arrays has a first, central scan range. The other antenna array includes antenna elements that can be controlled to scan regions outside of the first, central scan range.
Claims20
An antenna array structure comprising:
- a planar array reflector;
- a central beam forming antenna array located on the planar array reflector and configured to form radio frequency (RF) signals having a beam peak that is adjustable within a central scan angle range relative to a propagation axis that is normal to the array reflector;
- and
- a wide beam forming antenna array located on the surface of the planar array reflector and configured to form RF signals with a beam peak that is adjustable within a wide angle scan range that at least partially exceeds the central scan angle range.

A method of transmitting an RF signal using an antenna array structure that comprises a planar array reflector;
- a central beam forming antenna array located on the planar array reflector and configured to form radio frequency (RF) signals having a beam peak that is adjustable within a central scan angle range relative to a propagation axis that is normal to the array reflector;
- and a wide beam forming antenna array located on the surface of the planar array reflector and configured to form RF signals with a beam peak that is adjustable within a wide angle scan range that at least partially exceeds the central scan angle range, the method comprising:
- selecting at least one of the central beam forming antenna array and the wide beam forming antenna array based on a desired propagation angle;
- and
- adjusting the amplitude and phase of RF signals provided to antenna elements of the selected antenna array to achieve the desired propagation angle for transmitting the RF signal.
