A phased array antenna system comprising a plurality of isotropic radiating elements and/or omnidirectional receiving elements addressing close in fields and a plurality of non-isotropic radiating elements and/or non-omnidirectional receiving elements addressing remote fields with the combined elements used to extend the maximum range of the antenna system without increasing the number of element nor the output power of the antenna. The non-isotropic radiating elements and/or the non-omnidirectional receiving elements can be formed by adding focusing structures such as lenses or reflective structures in the radiating path of isotropic radiating elements and/or omnidirectional receiving elements. Antennas with combined isotropic radiating and non-isotropic radiating elements can be utilized for electromagnetic phased array radar, communication and imaging systems and for acoustic phased array sonar or ultrasound systems.

An RF lens includes a multitude of radiators adapted to transmit radio frequency electromagnetic EM waves whose phases are modulated so as to concentrate the radiated power in a small volume of space in order to power an electronic device positioned in that space. Accordingly, the waves emitted by the radiators are caused to interfere constructively at that space. The multitude of radiators are optionally formed in a one-dimensional or two-dimensional array. The electromagnetic waves radiated by the radiators have the same frequency but variable amplitudes.

A beamforming network for use with a plurality of antenna elements arranged in a planar array of linear sub-arrays includes first and second sets of beamforming sub-networks.
