Abstract
A Moxon antenna is a special case of Yagi-Uda antenna with folded dipole and single folded reflector. It is a simple antenna with no side or back lobes .It has a moderate gain and a high front-to-back ratio. It can be designed for different frequency bands, starting from HF up to centimetric and even millimetric bands. It can be built as a wire antenna or printed on a dielectric substrate. In this paper we are going to study the development of Moxon antenna from simple dipole antenna and the design and optimization of printed Moxon antennas on different substrates, trying to investigate the effects of substrate material on the antenna performance.
