This antenna is one in a series of L-Band antennas. This antenna is part of an L-Band, satellite, asset tracking modem. The design is optimized to yield a simple, low cost product with excellent reproducibility.
The Right Hand Circularly Polarized Patch is designed for best possible hemispheric coverage. A 5 Watt SSPA is mounted to the back of this antenna. The patch antenna provides sufficient heat radiation and no additional heat sink is required. The antenna is grounded to protect the SSPA against static discharges.
A highly efficient switched mode power supply is integrated. Power is supplied through the coax cable.
