Claim Text:
1. An antenna configuration, comprising: a tunable multi-feed antenna configured to wirelessly transmit electromagnetic radiation at a frequency band; a transmit module configured to generate a plurality of signals having a phase shift or amplitude difference therebetween, wherein the plurality of signals collectively correspond to a signal to be transmitted; a plurality of antenna feeds coupled to different spatial locations of a single excitation element of the tunable multi-feed antenna and configured to provide the plurality of signals, respectively, to the tunable multi-feed antenna; an adjustment module configured to selectively adjust an antenna input reflection coefficient of the tunable multi-feed antenna to define a frequency of transmission by independently controlling at least one of a phase or an amplitude of one or more of the plurality of signals to generate a phase shift or amplitude difference between at least two of the plurality of signals; wherein the phase shift or amplitude difference of the plurality of signals define frequency characteristics of the frequency band.
