Abstract
Increasing demand for communications systems for facilitating communications such as communications satellites leads to continuously increasing frequency bands of the signal for communication and the quantity of beams carrying the signals may make it more and more difficult to have a significant number of mechanical and electrical components concentrated in a location in proximity to the array while maintaining antenna efficiency. Provided is a direct radiating array (“DRA”) antenna for transmitting or receiving an electromagnetic radio frequency (“RF”) signal of at least one predetermined signal frequency band and a method of assembly that overcomes at least some of the disadvantages of existing direct radiating array systems and methods. The DRA antenna comprising a plurality of radiating elements, a plurality of RF signal chain paths and a beamforming network board having a plurality of electrical ports for electrically connecting to the plurality of RF signal chain paths.
