ZED-F9P-Integration manual
An L1 + L2 stacked patch antenna must have a good band-pass performance from the patch
elements with low attenuation from SAW band-pass filtering. An example of the measured
frequency characteristics of a low-cost L1 + L2 antenna is shown below.

The u-blox low-cost antenna design is shown below, followed by some examples of antennas from
other manufacturers which can be used with ZED-F9P.
