Abstract
A shared antenna in that a linear antenna is electrically connected to the upper end of a power pin of a microstrip plane antenna via a capacitive element. The shared antenna is used in both satellite communications and ground communications and can be used without a need of mechanical switching of the antenna. Further, crimped radiating elements having spatial expansion are electrically connected to the vicinity of the upper end of a feed pin of a microstrip plane antenna via a capacitive element, thereby realizing superior impedance matching and radiation patterns of the shared antenna.
