PCB Antenna Reference Designs

PCB Antenna

Have you ever built a wireless project and weren’t sure how to make one of those awesome (and cheap!) PCB antennas? “What low-cost solutions does our Antenna Board #referencedesign contain?” said Texas Instruments (TI) recently via Twitter.  This older reference design contains some comprehensive designs for sub-1 GHz and 2.4 GHz antennas.

While TI’s documentation can be difficult to navigate, there are many hidden gems, and this is one of them. While TI created these designs for use with their wireless products, they will work on any device which utilizes the same wireless base frequency. For example, you could use any of the 2.4 GHz antennas with any Bluetooth, WiFi (2.4 GHz), or Bluetooth Low Energy chips. Simply open up their Antenna Selection Quick Guide document and navigate to the specific design for whichever antenna you would like to build.

For a more detailed overview of what goes into designing and testing a PCB antenna, check out this hack which we featured back in 2010. With the internet of things coming into its own, wireless projects will become more and more prolific, making PCB antennas more important than ever.

DC Entries: LVP/Logic probe and a wireless antenna


I’m sick today, but finally getting some entries up. [Albert] designed this board which can be either a low voltage PIC programmer or, if you lack a programmer to get the initial flash data on the PIC, the through hole components make a logic probe. He rounded out the board with a silk screened logo and a prototyping area. He was also kind enough to provide an eagle library with the Hack-A-Day logo.

Our second featured entry of the day: [Pablo] put together a simple Hack-A-Day 2.4ghz antenna. He built and tested it – It functions nicely as a directional 2db antenna. His proposed use: limit your neighbors access to your AP by aiming the unetched backside at them.
