Design Examples
The following section shows a series of design examples. Each of these has been tuned for a particular
design, so a cut-and-paste approach will not necessarily ensure optimum performance. However, these
designs are a good starting point for further optimization, and they indicate the approximate size of the
particular antenna.

F-antennas
F-Antennas 2 and 3 have some of the FR-4 material cut away, to improve efficiency. F- Antenna 3 has been
designed for some loading by a plastic casing.
