The 20-41 Series of active GPS (Global Positioning Satellite Systems) antennas, with integrated Antenna Electronics (AE), are designed to operate in the GPS L1 and L2 bands. The antenna element operates with nominal hemispherical coverage to allow reception of signals from a number of satellites. It consists of a dual micro strip stacked patch radiating element fed by a 90 degree hybrid arrangement giving Right Hand Circular Polarization (RHCP) reception, excellent symmetry and cross-polar performance across the whole bandwidth.
