DESIGN OF 2.4/5.8GHz DUAL WiFi ANTENNA OF HIGH EFFICIENCY BY COMMON CONNECTION LINE

摘要

An antenna device according to an embodiment of the present invention includes: a feeder unit for supplying a current through a feed line attached to one surface of a substrate; an antenna unit in which a plurality of antennas are located and which receives the current with a coupling feeding method by connecting each of the plurality of antennas to the feeder line of the feeder unit; and a connection unit for adding a common connection line between the plurality of antennas to control the current flowing in the antenna unit. Accordingly, the present invention can reduce the interference of the antenna and improve the performance of the antenna.;COPYRIGHT KIPO 2018
