Multifrequency Position, Navigation, and Timing (PNT) Antenna Solution

Objective: Develop a multiple Radio Frequency (RF), aka “Multifrequency,” configurable patch antenna that can be utilized in cannon and missile-based Precision Guided Munitions (PGM) to support Multi Global Navigation Satellite Systems (M-GNSS) Positioning, Navigation, and Timing (PNT) signals and PNT Signals of Opportunity (SoOp), with minimal impact to received signal power. Description: The modern battlefield includes Electronic Warfare (EW) targeting a variety of RF signals, making single-frequency systems vulnerable to brute-force jamming. PGMs require frequency diversity in small, gun hardened, PGM Form Factor (FF) patch antennas to support a variety of M-GNSS and SoOp PNT signals and ensure successful operations in a contested EW environment. To maximize the capabilities of PNT systems, the Multi-frequency antenna should be tunable (or configurable) such that desired frequency bands can be determined at the time of mission execution. As an objective requirement, support continuous frequencies from UHF to X-band.
