GP-Patch-Antenne

Q: I have two video systems that operate at 900Mhz and 1.2Ghz. Can I use the GP Patch?
A: You can use it at other UHF and microwave frequencies by re-scaling the design. This is a process where ALL the dimensions are increased to suit the required operating frequency. It is important to know the exact frequency of your system, so a frequency counter is often needed.
To scale the antenna for your required frequency please use this formula:
Scale Factor = 2400Mhz / Required Mhz
Example: Cheap imported "1.2Ghz" wireless video system (usually operate at 1.16Ghz):
2400Mhz / 1160Mhz = 2.069
