PCB trace antenna

If you’re working on a device that includes RF wireless, [Colin's] Guide to PCB Trace Antenna Design might clear some headaches when sending off for PCBs. While it is directed at devices transmitting at 2.4GHz, the techniques and recommended equipment (read: espresso smith charts and network analyzers) should work for almost any frequency. While trace antennas aren’t as easy to implement as a measured wire, the space benefits make up for the difficulty. Unless you don’t mind how larger your project is, did someone say cantenna?
