Abstract:
An array antenna comprising:a first radiator for coupling to a feed and for receiving energy from the feed and radiating the received energy;a first array of radiators disposed so that each radiator within the first array of radiators is in close proximity to the first radiator and spaced therefrom for parasitically coupling to the first radiator; and,a second array of radiators disposed so that each radiator within the second array of radiators is in close proximity to a radiator in the first array of radiators and is spaced therefrom for parasitically coupling to said radiator from the first array of radiators and wherein some of the radiators in the second array of radiators is in close proximity to a plurality of radiators from the first array of radiators such that each of said some radiators is for being fed by at least two radiators from the first array of radiators.
