Samenvatting

A wide-scan and broadband focal-plane array (FPA) concept is introduced that provides high antenna gain and effective isotropic radiated power (EIRP) with electronic beam-steering within a relative large field-of-view (FoV) up to +/-200. The antenna uses a bi-focal double-reflector concept that optimizes the illumination of the focal-plane region. In this way, we have reduced the required size of the feed array and have maximized the number of simultaneously active array elements. By using a photonics beamformer, a broadband system for the 20-40 GHz band can be created with a fiber-based interface to a central processing unit. This hybrid antenna system proves to be a very interesting concept for future 5G and beyond-5G millimeter-wave base-stations, two-way satellite communication systems and point-to-point wireless backhaul systems. A silicon BiCMOS low-noise amplifier and a photonic integrated circuit for the optical beamformer have been developed and integrated in the overall system. A system-level demonstrator was developed and experimentally validated in receive mode. Our concept provides an antenna gain of more than 40 dBi over a FoV of +/-15 degrees at 28.5 GHz.
