The patent pending revolutionary tiny but powerful active SMD GPS patch antenna allows for
optimal performing GPS by combining the ceramic patch, SAW, LNA, and feed pad in one
integral package. Horizontally mounted on a board as any other components, GPS device
designers no longer need to compromise in performance. This antenna takes up less
footprint and volume than even the smallest poorly performing metal, ceramic and pcb linear
antennas, which have an automatic drop of 3dB gain (half the GPS signal strength) compared
to this antenna. Nothing works better at this size.
The right hand circular polarized patch is ideally matched to the GPS signal, tuned for maximum
gain, minmal axial ratio. The SAW is placed in front of the LNA, helping prevent saturation
due to nearby radio transmitters, and the possibility of radiated spurious emissions through
other radio systems.
The LNA placed directly underneath the patch feed ensures the signal is boosted before ambient
noise can enter the transmission lines between the antenna and the GPS receiver module on
the board, a unique advantage over all other on-board antenna technology. It has a
wide-band input voltage between 1.8V to 5.5V to cater for all electrical systems.
The unique SMD structure enables pick and place and reflow soldering onto boards in high
volumes, with highest reliablity, compared to traditional cabled solutions. All that is needed is
to run a 50 Ohm co-planar waveguide to the SMD GPS receiver module.
The patch antenna can be tuned for each device environment if necessary.
Patented 10mm Vertically mounted SMD active GPS AP.10 series antennas are also available from Taoglas.
