Abstract

A modified printed Yagi antenna with a simplified feeding mechanism is proposed. In the new design, the driver dipole is fed by a transmission line formed by two parallel strips printed on the opposite sides of the dielectric substrate. The parallel strips are connected to a microstrip line with a truncated ground plane. This simplified feeding structure results in the reduction of the transmission line length, and, consequently, the radiation losses. The analysis of the modified Yagi antenna is performed numerically using commercial FEM and FD-TD software.
