An overhead V-shape printed dipole array antenna for toll plaza application

In this paper a new fix-point array antenna is introduced to support extended requirements for electronic toll collection application, as taller gantry with narrower beam width to reduce the effect of cars in side lanes. The printed dipole antenna as a wideband, simple and low-cost structure has been used as a single element. In this work the design procedure of 4 x 6 array including feeding network is presented. The antenna meets stringent requirements on pattern/polarization performance and full pattern measured data are presented.
