  • Author: Roshni Prasad

The increasing interest in high-precision GNSS/GPS services has led to the development of novel antenna solutions to service various end-customer applications in markets such as agriculture, recreation, surveying & mapping, and timing.Multi-band receivers and antennas are required to derive a higher-precision rate on positioning. However, using dedicated antennas for widely separated multi-band support may introduce several challenges in the design, including increased occupancy in board space and coupling. This application note reviews how these challenges are addressed by employing a single multi-band antenna. The discussion primarily focuses on Abracon’s internal and external antenna solutions that can cover multiple GPS and/or GNSS bands as a single entity for precision positioning applications.
