Default Franklin Antenna (Collinear) for 2.4 GHz with 20.5 dBi of Gain

Franklin Antenna (Collinear) for 2.4 GHz with 20.5 dBi of Gain
Impedance: 200 Ohms
VSWR: perfect!

Anyone interested on the design? The impedance have to be adopted via
1:4 lambda/2 balun.
Site containing NEC2-Code and model source code. Also some pictures on
radiation patterns are included. Average Gain Test indicates the
correctness of the model.

Here's a similar style antenna written in English. This antenna is shorter,
has less gain, but does show matching section.
