Overview
Fully polarized suppression Anti-Jamming GNSS Antenna PT024 is a dual-frequency high-precision positioning antenna, primarily designed for environments with complex electromagnetic interference, high power, and strong multipath effects. This antenna features vertical and horizontal two-dimensional polarization suppressors, functioning similarly to RHCP helix antennas and spatial filtering under high impedance. This effectively suppresses the reception of all odd and even LHCP & RHCP signals from the back of the antenna, as well as low elevation multipath signals of the same frequency and out-of-band noise signals, thereby increasing the electrical length while maintaining a compact antenna size. This enhances forward radiation efficiency by directing edge charge flow towards the back of the PCB.
