A Compact Triple-band Filtering Microstrip Patch Antenna with the Same Polarization Planes

Abstract

A novel compact filtering microstrip patch antenna with triple-band operation is presented for WLAN/TD-LTE wireless applications. The proposed design is composed of a patch with slot-loaded parasitic elements and a stepped-impedance resonator which shares the same apertured ground. Using full-wave simulator HFSS, the broadside coupling coefficient can be extracted to determine the dimension of the aperture. The antenna has similar broadside radiation patterns in both E- and H-planes in the three frequency bands. Meanwhile, the antenna provides good selectivity as well as the same polarization planes.
