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.

Claim (Index 1):
Antenna apparatus for transmitting/receiving electromagnetic radiation defining a wavelength, the apparatus comprising:\n at least one lower machined plate; and at least one upper machined plate including:\n a radiating element layer including an array of radiating elements each having a center, wherein the distance between the centers of adjacent elements in said array is less than one wavelength; and \n an H-plane splitter layer below said radiating element layer and including H-plane splitters each having an H-plane splitter input facing said lower plate and a pair of H-plane splitter outputs which respectively connect the H-plane splitter to a pair of said radiating elements, and \n wherein the antenna apparatus further comprises an E-orientation feeding network layer having an input and comprising:\n E-plane splitters receiving the wave from the feeding network input and defining multiple feeding network outputs, wherein an individual H-plane splitter input connects individual ones of said H-plane splitters to respective outputs from among said multiple feeding network outputs, thereby to enable the H-plane splitters to split the electromagnetic radiation travelling from the feeding network input to the radiating elements; and \n one or more hollow waveguides interconnecting the E-plane splitters.
