In this paper, sectorial and circular slot Pac-man antenna for dual band frequency, 1.7 GHz for indoor wireless personal communications and 2.45 GHz Industrial science and medical (ISM) was proposed by using polypropylene (PP) flat pressed temperature con-trolled method. The method and material was chosen to reduce the overall cost and proposed new substrate with density =0.9gcm-3, dielectric constant = 2.57 and loss tangent = 0.0352.The dual band operation was distributed by sectorial slot design with, small circular slot to control and tuning the operating frequency. The back to back comparison between normal circular patch with Pac-man antenna using proposed substrate are dis-cussed and overall result distributed that there is no significant changes for gain, directivity, efficiency, vswr and physical size even though the proposed Pac-man antenna perform for dual band operation hence it is al-so improve the bandwidth of 17% compared to normal circular patch. The final Pac-man design fabricated using proposed polypropylene substrate (PP100) was then analyzed by using OTA-500 ATENLAB anechoic chamber.
