SMALL MONOPOLE ANTENNA WITH LOOP ELEMENT INCLUDED FEEDER

摘要

A small monopole antenna with a loop feed terminal is provided to increase space usability of cellular phone case by securely guaranteeing an electrical length of the antenna by providing the feed terminal in the middle of a loop-type element. A small monopole antenna with a loop feed terminal includes a loop-type element(1a), a non-feed type monopole antenna element(1b), a ground element(2), and a first connector(3). The loop-type element is formed along a plane to form a loop and includes a loop feed terminal in the middle of the loop. One end of the non-feed type monopole antenna element is connected to a conductive line of the loop-type element while the other end thereof is connected to the ground element. Ground element connects the other end of the non-feed type monopole antenna element to a ground potential. The first connector couples an external device with the non-feed type monopole antenna element such that power is supplied to the loop feed terminal of the loop-type element.
