ABSTRACT:
An antenna comprises an arrangement of electrically conducting segments, the arrangement including intersection points where two or more electrically conducting segments are in electrical communication. Example antennas include a plurality of capacitors located within some or all of the electrically conducting segments. Capacitance values can be determined using an optimization algorithm to obtain desired values of antenna resonance frequency (or frequencies), bandwidth, and/or radiation pattern, and may be adjusted in order to control an antenna parameter such as beam steering direction.
