High-Frequency RF Antenna Design & Engineering

The contract requires the design and engineering of two cavity-backed spiral antenna sets, one with eight elements spanning the 2 to 18 GHz frequency range and another with thirty-two elements operating from 8 to 18 GHz. Both antenna sets must support left-hand and right-hand circular polarization to ensure versatile communication and signal reception capabilities across a broad spectrum. The work involves full lifecycle engineering from concept development through prototype fabrication and validation, with an emphasis on performance, reliability, and compliance with military-grade specifications. The antennas are intended for deployment in advanced electronic systems requiring high-frequency, wideband operation in challenging environments. The contract is classified as a subcontract under NAICS code 541715 for research and development in physical, engineering, and life sciences, issued by the Department of National Defence of the Government of Canada. Proposals must be submitted by May 14, 2026, and performance is expected to occur within the National Capital Region. Although no set-aside provisions are specified, the effort supports Canada’s defense technology modernization objectives, requiring vendors to demonstrate technical expertise in high-frequency antenna systems, electromagnetic modeling, and fabrication of compact, high-density phased arrays. The solicitation is publicly accessible through Canada Buys, and successful bidders will be expected to deliver fully documented designs, test data, and supporting engineering artifacts to meet government procurement standards.
