The polarization of yagi antenna
WebbA novel broadband planar antenna based on the classic Yagi-Uda dipole array is presented. This "quasi-Yagi" antenna achieves a measured 48% bandwidth for VSWR <2, better than 12 dB front-to-back ratio, smaller than -15 dB cross polarization, 3-5 dB absolute gain and a nominal efficiency of 93% across the operating bandwidth. Finite-difference time-domain … WebbEither both systems (both dipoles) are driven by one signal, but with different phase position, so a circular polarization is achieved. For this purpose, the X-position of the …
