Band-agile apertures for 5G & 6G
Worldwide 5G allocations span an increasingly wide range of frequencies and this trend is expected to continue with future networks. Cheshir GRIN antennas are the only apertures that can beamform over any 5G band on any 5G radio in any country – while still meeting the SWaP-C requirements for light vehicles and small platforms.
Ultrawideband sensing for EW/Radar
Emerging military sensing applications demand ultrawideband operation, high sensitivity, and resistance to jamming. Cheshir GRIN receive-antennas operate over a bandwidth of 5:1 or more with extremely low power consumption and employ multiple high gain beams to eliminate interference effects.
SATCOM
High resolution sensing
The proliferation of large satellite constellations - and their ground terminal counterparts – presents enormous sensing and acquisition challenges. A single low-power Cheshir GRIN aperture can support hundreds of independent high-gain beams to enable extremely high resolution RF imaging over a wide field of view – both in-orbit and on the ground.
Ku/Ka Receive Terminals
Cheshir GRIN apertures support wide field of view beamforming over extremely wide bandwidths, making them ideal for SATCOM-receive applications requiring both Ka- and Ku- band coverage in a single aperture. Such terminals will also exhibit extremely low power consumption and electronic complexity relative to comparable phased arrays.
Commercial Wireless
Cost-effective mmWave:
Emerging backhaul and fixed wireless access applications demand the provision of sustainable antenna infrastructure with high gain and dynamic beam control. Cheshir GRIN antennas provide wideband beam-steering capabilities while consuming substantially less power than comparable phased arrays, reducing energy consumption and cost while maintaining high performance.
Base station antennas
Maintaining mobile network quality is challenging in high-population density scenarios such as stadia, airports, or urban centers. By forming multiple spatially orthogonal beams, Cheshir GRIN antennas achieve a high degree of sectorization across multiple frequency bands simultaneously, dramatically improving throughput in capacity-constrained applications.
