Abstract

The invention discloses a coplanar waveguide feed directional diagram reconfigurable planar monopole antenna, which comprises a metal coating, two micromechanical system (MEMS) switches and a medium substrate. The metal coating comprises a radiation patch, a coplanar waveguide feeder line and a coplanar waveguide floor. The coplanar waveguide floor comprises a first coplanar waveguide floor, a second coplanar waveguide floor, a third coplanar waveguide floor and a fourth coplanar waveguide floor. The coplanar waveguide feed directional diagram reconfigurable planar monopole antenna is simple in structure, the state of the coplanar waveguide floor can be effectively changed only by controlling the on-off of a first MEMS switch and a second MEMS switch, therefore, the reconfiguration purpose of an antenna radiation directional diagram can be realized on the premise of maintaining the working frequency. The antenna is used for transmitting and receiving electromagnetic waves and has the characteristics of small size, light weight, convenience in machining and wide working band.
