1. A segmented ultra-wideband antenna system for multiple frequency bands, comprising:
a platform having a circular shape structure;
a plurality of antennas adapted to affix to said platform using one or more fasteners, wherein said plurality of antennas comprises:
a first antenna having a main parabolic reflector with an axially displaced ellipsoid (ADE) sub-reflector configured to transmit and receive high-band radio frequency signals, wherein said first antenna is a dual reflector antenna;
a second antenna having a circular horn antenna configured to transmit and receive medium-band radio frequency signals, wherein said second antenna is a ridged conical horn antenna;
a third antenna configured to transmit and receive low-band radio frequency signals,
wherein said third antenna comprise:
a primary ridged horn antenna having a rectangular shaped flare configured to transmit and receive the low-band radio frequency signals from upper ridge and lower ridge in top and bottom directions, thereby supporting vertical polarization; and
a secondary ridged horn antenna having a rectangular shaped flare configured to transmit and receive the low-band radio frequency signals from left ridge and right ridge in left and right directions, thereby supporting horizontal polarization; and
a controller configured to auto-select at least one or more of said first antenna, said second antenna and said third antenna for transmitting and receiving multiple range radio frequency signals.
