  • 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. However, using dedicated antennas for widely separated multiband 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.
