Abstract
An antenna array configuration is provided with h-plane splitters between ends of a feeding network and radiating elements e.g. horns, thereby to reduce the distance between the centers of the horns to less than one wavelength which results in a better side lobe level. A method of manufacturing upper and lower plates together constituting an antenna is also provided, typically making each plate in a single operation, by dividing the feeding network's waveguides at the centre where there are no cross currents so as not to disturb propagation in the feeding network. The radiating elements, h-plane splitters and upper half of the feeding network may be fabricated in one plate without undercuts hence simplifying manufacture of the plate which may for example be formed using a simple molding machine or a 3 axis-CNC machine.
