COPLANAR WAVEGUIDE FEED SLOT ANTENNA HAVING DOUBLE RESONANT CHARACTERISTIC

摘要

A coplanar waveguide feed slot antenna having double resonant characteristic is provided to implement an antenna operating in the duplex resonance frequency by diversifying the resonant frequency according to the parameter between the vertical slot and the external slot. A ground plane(100) performs the grounding function. A lower center of the external slot(210) is opened. A CPW feeder(300) is made of a first CPW feeder(301) and a second CPW feeder(302). The first CPW feeder is perpendicularly connected from the bottom side of the ground plane to the left side open circuit(211) of the external slot. The second CPW feeder is perpendicularly connected from the bottom side of the ground plane to the right side open circuit(215) of the external slot. A vertical slot(220) is made of a first vertical slot(221) and a second vertical slot(222). The first vertical slot is arranged between the left side pattern(212) of the external slot and the first CPW feeder. The second vertical slot is arranged between the right side pattern(214) of the external slot and the second CPW feeder.
