Antenna Research Associates

What Antenna Research Associates does

Antenna Research Associates (ARA), founded in 1981 and headquartered in Laurel, Maryland, designs and manufactures advanced radio frequency (RF) subsystems, antenna systems, and electronic warfare equipment for U.S. Department of Defense customers, military services, and Tier-1 defense prime contractors. The company's product portfolio spans Active Electronically Scanned Arrays (AESA), phased arrays, conformal electronically steerable antennas, direction-finding and interferometer arrays, ELINT/ELINT antennas, MILCOM solutions, radar subsystems including AESA C-UAS and missile seekers, and SATCOM terminals, covering frequencies from 10 Hz to 80 GHz across airborne, shipboard, and land-based platforms. Notable technical capabilities include Low Profile Conformal Electronically Steerable Array technology (1-50 GHz, PCB-based construction, +/-70 degree scan), the ISR Systems AESA (2-6 GHz airborne array qualified to DO-160 and MIL-STD standards), and the CISR Systems Interferometer (UAS-mounted direction-finding pod).

ARA generates revenue primarily through the design, manufacture, and sale of both standard and custom defense electronics with quote-based pricing under multi-year government contracts. The company pursues an enterprise field sales motion targeting defense and aerospace markets, supported by a contracts center, dedicated sales line, and direct engagement via email and phone. Marketing and business development are executed through defense industry events (e.g., AFCEA conferences with live AESA demonstrations), technical thought leadership content, and a corporate social media presence. Following its acquisition by OceanSound Partners in October 2024, ARA operates as a private equity portfolio company with management retained in operational roles and equity, and has added a Chief Growth Officer, Chief Operating Officer, and Chief Technology Officer to support expansion across defense mission requirements.
