A Study on Inverted Triangle Structural Planar Monopole Antenna with Edge

In this paper, inverted triangle structural planar monopole antenna with Edge for UWB Communication (3.1 ~ 10.6 GHz) is presented. The antenna have broadband property structurally through inverted triangle structural planar monopole which have edge. Monopole and ground of proposed antenna exist on coplanar plane, and excite as CPW. It used FR4 dielectric substrate of , and the size is . Return loss is more than - 10dB in 3.1 ~ 10.1 GHz (7.0 GHz). Radiation pattern is about the same that of dipole antenna at all frequency. At measured result, max gain is 8.44 dBi at E - plane.
