Abstract
A phased array is disclosed, including: a base layer including a substrate with a plurality of protruding posts, for stopping wave propagation along the base layer, and a printed circuit board (PCB) arranged on the base layer, and including at least one phased array radio frequency (RF) integrated circuit (IC) on a first side of the PCB facing the base layer and the protruding posts. The PCB further includes feeds for transferring of RF signals from the phased array RF IC(s) to an opposite second side of the PCB. A radiating layer, including a plurality of radiating elements for transmitting and/or receiving RF signals from the phased array antenna is also provided, together with a feeding layer for transfer of RF signals, arranged between the feeds of the PCB on the second side and the radiating elements of the radiating layer.
