RF2B designed a phased array proof-of-concept for small cell CBRS base stations at 3.5 GHz, where fast trade-off studies were needed to select array architecture, spacing, tapering, and steering performance—while also accounting for the feed network and mechanical environment (enclosure + radome). Using Altair FEKO’s finite array analysis and built-in array synthesis scripting, RF2B accelerated model build time and reduced memory demands, enabling faster iterations on a standard desktop workstation. The fabricated array was then validated in an anechoic chamber, showing strong agreement with FEKO simulation results.

Venti Group supported a Tier 1 partner installing a multi-carrier 5G network in a stadium for the 2022 NFL championship game. The antenna had to operate in a difficult RF location—under a seat near a concrete floor—and remain compact due to tight packaging constraints. Venti used Altair FEKO to rapidly assess how design changes affected performance, re-optimize designs in days rather than weeks, and simulate RF environmental effects when there wasn’t time for repeated build-and-test cycles. FEKO helped the team adapt as constraints grew—resizing, routing, mounting durability—while keeping the design viable through each iteration.
