Abstract:
1. A wireless communication device comprises: a receiver section operable to convert an inbound wireless signal into an inbound symbol stream; a transmitter section operable to convert an outbound symbol stream into an outbound wireless signal; an antenna interface operable to: a multiple excitation point antenna assembly that includes a plurality of interconnected interwoven spiral antenna units with selectable shifted excitation points, the plurality of interwoven spiral antenna units each including both non-inverted and inverted spiral sections and coupled together at an angle relative to a 0° phase shifted one of the plurality of interconnected interwoven spiral antennas units, the angle equal to one of the selectable shifted excitation points by plurality of connection traces connecting the non-inverted spiral section of at least one the plurality of interwoven spiral antenna units to the inverted spiral section of at least an adjacent one of the plurality of interwoven spiral antenna units, wherein an interwoven spiral antenna unit of the plurality of interwoven spiral antenna units receives a corresponding one of the plurality of phase-shifted received wireless signals and transmits a corresponding one of the plurality of phase-shifted outbound wireless signals.
