Design of minskowsi fractal antenna for dual band application

A reduction in physical size and multiband capability are important design requirements for antenna in future wireless devices. Designed process involved a mathematical analysis, numerical methods simulation and experimental measurement on fabricated antenna. The design and simulation process on purpose antenna was carried out using Microwave Office software. Then the proposed antenna was fabricated on FR4 Epoxy/glass substrate at KUiTTHO Printed Circuit Board (PCB) Fabrication Laboratory. Fractal antenna properties were observed from the measurement of return loss, standing wave ratio (SWR) bandwidth, beamwidth and also radiation pattern are presented in this project. Global Positioning System (GPS at 1.5 GHz) and Global System for Mobile (GSM 1800) frequencies are used as references frequency. The overall results were obtained and satisfied the fractal structure and fractal concept which is the fabricated antenna showed multiband frequencies when iteration is done and the size of antenna turn out to be smaller.
