Antenna system for optimizing antenna pattern

Abstract

The disclosure provides an antenna system for optimizing antenna pattern, comprising an open gap between a first antenna metal portion and a second antenna metal portion. A first feeding contact is electrically connected to the first antenna metal portion, and a second feeding contact is electrically connected to the second antenna metal portion. A first ground contract is electrically connected to the first antenna metal portion, and a second ground contact is electrically connected to the second antenna metal portion. A first matching circuit is electrically connected to the first feeding contact, and a second matching circuit is electrically connected to the second feeding contact. A plurality of first ground paths provides connections to the first feeding contact. One end of a first switch circuit is electrically connected between the first feeding contact and the first matching circuit, and the other end of the first switch circuit is electrically connected to the plurality of first ground paths to selectively conduct the first feeding contact to one of the first ground paths.
