The ASGGB184.A from Taoglas is a Single Band Active GNSS Patch Antenna that covers GPS, GLONASS, BeiDou and Galileo bands. It consists of a two-stage LNA and a front-end SAW filter to reduce out of band noise such as from nearby cellular transceivers and this improves the probability of the wireless device passing radiated spurious emissions certification. The active circuitry is embedded between the ceramic patch and PCB base making it easy to mount directly on a PCB. This surface mount active GNSS antenna measures 18 x 18 mm and requires a 70 x 70 mm ground plane.
The RHCP polarized antenna provides an average gain of -2.1 dB while the LNA provides a gain of 29 dB with a noise figure of less than 2.19 dB. The active circuitry requires a DC supply of 1.8-5.5 V and consumes less than 11.23 mA of current. The antenna is ideal for navigation, commercial transportation and asset tracking applications. The antenna is produced in a TS16949 automotive quality approved facility and is 100% tested for gain (S21) and return loss (S11) to ensure total consistency of performance.
