Allystar Technology Co. Ltd., headquartered in Shenzhen, China, is offering new patch antennas: the AGR6302 and AGR6303. Both GNSS antenna models are designed for precision dual-frequency positioning.

AGR6302 is capable of receiving L1/L2 bands, and AGR6303 is capable of receiving L1/L5 bands. They are designed for UAVs, precision agriculture, autonomous vehicles and other applications where precision matters.

The AGR6302/AGR6303 active antenna is designed by unique technology to cover GPS, BDS, Galileo, GLONASS, IRNSS and the QZSS system (see table).

The antenna features stable signal quality at low cost. It employs a stack four-feeds antenna architecture with hybrid to achieve the multi-band operation, lower axial ratio, wider half-power beamwidth and excellent right-hand circular polarization, the company said.

With its new architecture, the active part has two stages. It has two level low noise amplifiers (LNAs) —one for the lower bands, the other for the higher bands. Then, the combiner and the third-level LNA output the RF gain to receiver. With this architecture, the antenna provides an excellent noise figure/RF linear and LNA gain, and out-band rejection, resulting in good signal-to-noise ratio and anti-interference.

It is housed in a compact, industrial-grade waterproof and magnet mount enclosure. Using internal magnets, the antenna can be installed almost anywhere, allowing for greater flexibility.
