A
mobile antenna for multimedia communications with Ku-band geostationary
satellite KOREASAT-3 and JSAT-2A is presented. The forward link of the
satellite communication is 11.7
to 12.75 GHz, and the return link is 14.0 to 14.5 GHz.The mobile antenna is designed to
be a stair structure using 24 active phased array elements in order to provide
a low profile, and to be at a non-periodic array distance using the genetic
algorithm.
Also, the designed antenna uses
the double beam forming method for stable satellite tracking. The fabricated
mobile antenna is examined using various experiments to confirm its capability
for practical application. From the measured results, the fabricated mobile
antenna system is confirmed to have a good performance.
