This paper presents the design of a small planar antenna with triangular patch for WiMax application. A conventional ground plane has been modified to reduce the size and increasing the bandwidth as well as to cover the WiMax band. The triangular-shaped patch is placed on top of the substrate and parasitic patch is placed at other side. By inserting a triangular patch in the coplanar ground plane, antenna is able to radiate at two resonance frequencies simultaneously. This antenna structure has been designed for covering (3.2 - 3.7GHz) and (5.2 to 5.8 GHz) WiMax bands. A low dielectric constant substrate with dielectric constant of 3.38 is selected to attain a compact radiating structure that also meets the challenging bandwidth requirement.
