Abstract :
In this article, we have proposed a novel Yagi antenna that has both compactness of resonant antenna and broadband characteristics of traveling-wave radiators. It is fabricated on dielectric substrate with a microstrip (MS) feed. The top layer consists a microstrip feed, a broadband microstrip-to-coplanar stripline (CPS) transition and two diopole-elements, one of them which is driver element is fed by CPS, and the second is director. The metal underside is a microstrip ground which serves as a reflector element and cancels using reflector dipole. This antenna is constructed on low cost substrate with 1.56mm thickness and εr = 4.12. The simulated bandwidth is about 35% and its gain is more than 5dB.
