A broadband plannar Quasi-Yagi antenna

摘要

The present invention is a mobile communication base stations for terrestrial digital broadcast receivers or used as a broadband planar quasi- cause ( quasi-yagi) relates to antennas , and more particularly, to a dielectric substrate and positioned on one side of the dielectric substrate , the central part is formed by two conductor strips that are spaced apart by a constant distance coplanar strip and the coplanar strip is embedded in the dipole and the coplanar strip feed , this is short-circuited termination broadband plane of the rectangular waveguide comprising a detached by a predetermined wavelength of the resonance frequency of the dipole in the upper portion of the microstrip line and the dipole feed in a coplanar strip gave - the Yagi antenna ;
