Disclosed is a switchable transmit and receive phased array antenna ('STRPAA'). As an example, the STRPAA may include a housing, a multilayer printed wiring board ('MLPWB') within the housing having a top surface and a bottom surface, a plurality of radiating elements located on the top surface of the MLPWB, and a plurality of transmit and receive (&#x201c;T/R&#x201d;) modules attached to the bottom surface of the MLPWB. The STRPAA may also include a plurality of vias, wherein each via, of the plurality of vias, passes through the MLPWB and is configured as a signal path between a T/R module, of the plurality of T/R modules, on the bottom surface of the MLPWB and a radiating element, of the plurality of radiating elements, located on the top surface of the MLPWB opposite the T/R module.

Switchable transmit and receive phased array antenna

A dual beam dual-selectable-polarization phased array antenna comprises an aperture unit, a printed wiring board, radiating elements, chip units, a pressure plate, and a rear housing unit. The printed wiring board has sub assemblies bonded to each other with a bonding material providing both mechanical and electrical connection. The printed wiring board is connected to the aperture unit. The radiating elements are formed on the printed wiring board. The chip units are mounted on the printed wiring board. The chip units include circuits capable of controlling radio frequency signals radiated by the radiating elements to form dual beams with independently selectable polarization. The pressure plate is connected to the aperture unit. The aperture unit is connected to the rear housing unit such that the aperture unit covers the rear housing unit.

A modularly expandable, phased array antenna having a rhomboidal shaped antenna aperture formed by a plurality of rhomboidal shaped subarrays. Each subarray has a rhomboidal shaped printed wiring board on which is formed a plurality of antenna elements, where the elements collectively form a rhomboidal shape in accordance with the printed wiring board. The rhomboidal shaped subarrays enable a modular aperture to be formed without producing any gaps between columns or rows of adjacently positioned subarrays. Thus, a uniform, consistent spacing is maintained between all the antenna elements on the subarrays. This improves antenna radiation and low observability performance for the antenna system, as well as reducing the overall size of the antenna aperture and its cost of construction.

Rhomboidal shaped, modularly expandable phased array antenna and method therefor

In accordance with an embodiment, a phased array antenna system includes a printed wiring board formed in rhombic shape that accommodates requirements for low observability and a beam forming network located within the printed wiring board. The beam forming network is located over substantially the entire printed wiring board. The embodiment includes connectors located on the backside of the printed wiring board. The back side connectors allow the array architecture to expand to include more subarrays and therefore allowing for more beam forming elements in a full size array than conventional phased arrays.
