Designed using a custom electro-ceramics formula, HP5354.A offers “stacked patch L1-L5 performance” within a single patch-in-a-patch solution, according to the company. It “has a passive peak gain of 2.61dBi optimised for GPS L1-L5, BeiDou B1, Galileo E1 and Glonass G1 operation with the next generation of dual-band GNSS receivers”.
Specifically, it is for RHCP (right-handed circular polarised) signals from 1,160 – 1,610MHz – intended coverage is BeiDou B1, B2a; GPS/QZSS L1, L5; Glonass G1 and Galileo E1, E5a.
Operation over -40 to +85°C
It is a dual-feed 50Ω antenna – the company has a hybrid coupler (HC125A) that can “combine the dual feeds for L1 patch offering high RHCP gain and optimal axial ratio for upper constellations including GPS L1, BeiDou B1, Galileo E1 and Glonass G1”, it claimed.
There is also a suitable dual-band front-end module called TFM.100B.
Why dual band?
“For decades, the industry has used single-band GPS, but emerging bands such as L2, L5, L6 and L-band offer designers a path to cleaner signals, improved gain and cm-level accuracy,” said Taoglas. “The same trend applies to global GNSS technologies, including GPS, Glonass, Galileo, BeiDou, QZSS, IRNSS, and SBAS.”
