In order to to reduce the amount of equipment a soldier must carry, a combined Communications and Navigation Antenna (COMM-NAV) antenna was proposed as a design objective at the MITRE Cooperation. This study aims to combine a UHF (communications)GPS (navigation) antenna into a single unit. The UHF band of interest was established to be 225MHz to 400MHz, whereas the GPS antenna is required to operate at L1 (1227MHz) and L2 (1575MHz) frequencies. This design is required to minimize interference between the two antennas. Through simulations and measurements, two antennas were designed to meet these requirements. The UHF antenna uses a sleeve monopole design, whereas a stacked, shorted annular ring design was selected to meet the GPS requirements.
