![]() The subject of this post – and where every RF design journey should start. This post – Step 1 of our Bluetooth antenna design guide – will help you do that in a few minutes. But you do need to understand a few basic principles to think the way Tim did. You don’t need a Masters in RF Engineering to choose the right antenna for your product. Within days, we gave him the simulation results he needed to confirm his design path. Tim asked BluFlux to help simulate the impact so he could adjust his RF design. When Tim received a new industrial design that needed an antenna, he knew right away he could not use a chip antenna. Many product designers who otherwise know a lot about electronics have come to us for antenna design help after they chose the wrong antenna – or used a “bluetooth chip antenna” the wrong way.Įxpert RF Engineers like Tim Chen, at Doppler Labs, know better. Who knows? You might get lucky… Or you might not. Go design your pcb and cross your fingers.Grab a part or reference design from the web.Google “bluetooth chip antenna” or “2.4GHz patch antenna” or “pcb trace antenna design”.If you’re in a hurry, you could always try the “Google, Grab and Go” approach: The official Bluetooth Specification tells you the frequency and bandwidth, but it gives you no guidance to navigate the vast sea of antenna options. When you’re designing a Bluetooth product, the sheer volume of off-the-shelf 2.4 GHz antenna options and reference designs may seem overwhelming. ![]()
