Use this file is to create a frame for the driven, reflector, and parasitic elements of a biquad yagi of your own specifications. The default values are for a 2.4 GHz antenna with a centre frequency of 2.442 GHz (centre of WiFi channels), but can be made resonant at just about any frequency, with as many elements as you wish.

I don't design antennas professionally, nor do I have any formal education in antenna theory and design. This file takes as many variables in to account as I could think of to allow you to create an antenna the way you want it.
