1. A wideband reconfigurable antenna system, comprising:
a single substrate;
a plurality of planar inverted-F antennas (PIFAs) integrated on the substrate, configured to operate within a frequency range of approximately 0.5 GHz to 4 GHz;
a plurality of square patch antennas integrated on the substrate, configured to operate within a frequency range of approximately 4 GHz to 10 GHz; and
a plurality of circular patch antennas integrated on the substrate, configured to operate within a frequency range of approximately 10 GHz to 40 GHz;
the plurality of PIFAs, the plurality of square patch antennas, and the plurality of circular patch antennas being configured in an aperture-in-aperture (AIA) configuration on the single substrate, enabling an operational frequency range of approximately 0.5 GHz to 40 GHz, and
the plurality of circular patch antennas including a slot to enhance bandwidth and to accommodate demanding frequency range.
