Direct-to-Phase-II STTR for a wideband antenna integrated with RF-photonics modules

**Buyer:** United States Air Force
**Posted:** November 07, 2026
**Respond By:** January 06, 2027
**Identifier:** DAF27TZ02-DV006
**NAICS:** 334220

The U.S. Air Force is seeking a prototype wideband antenna integrated with an RF-photonics module under a Direct-to-Phase-II STTR topic.
- **Government buyer:** Department of the Air Force, through the Department of War Small Business Technology Transfer (STTR) Program and Air Force SBIR/STTR office.
- **Primary requirement — topic DAF27TZ02-DV006:** Design, fabricate, integrate, and experimentally characterize a broadband antenna compatible with standard RF-photonic module packaging.
  - Demonstrate stable, efficient wideband performance, including performance beyond the Chu limit, while reducing size, weight, power, and cost (SWaP-C).
  - Report radiation pattern, return loss, efficiency, group delay, and isolation; compare proposed, simulated, and experimental performance.
- **Proposal and technical considerations:** Applicants must establish feasibility using research and development conducted outside the SBIR/STTR programs. The topic is subject to ITAR/EAR export controls. The initial notice also lists a CMMC Level 2 (Self) requirement.
- **Award context:** The topic index gives a maximum award duration of 24 months and a maximum award of $2 million. No specific dates or fixed contract period are provided.
- **OEMs and vendors:** No manufacturers, OEMs, or vendors are named in the materials.
- **Other topics listed in the broader BAA attachment:** B-52 Multi-Factor AI Performance Charts (DAF27TZ02-DV004) and RF-DASK (DAF27TZ02-DV005); their line items are included below because they appear in the attachment summary.
