Plannar Monopulse Antenna with Radial Line Feeding at 37 GHz

A new feeding structure based on parallel plates radial line applied on planar arrays is shown in this paper. When a high gain antenna for a high frequency system is being designed, low losses feeding networks must be taken into account [1]. Typically waveguide feeding networks are being used in this kind of applications. In order to show how parallel plate [2] [3] feeding networks works a planar array antenna working at 37 GHz frequency is presented.
