thought the on-board antenna on slide 18 would have cornered traces (vs right angle) ... have seen this approach on garage door openers for example (with tuner/attenuators) of course these are in the 300-400MHz range tho ...
And MiWi is for ISM: "The MiWi DE is ideal for the development of ISM-band wireless networking applications for the home and industrial automation, wireless sensor monitoring and control, and smart energy markets."
@pauln That's not our preference. We found that a wire connected to an SMA has the best performance. Unfortunately, the FCC says that the antenna needs to be attached in a way that others cannot easily adjust it so PCB is ideal for our application. The PCB antenna is tricky though because it's not very affordable to design, have a third party build, and then test multiple PCB layouts.
We are currently working on designing/testing a PCB antenna in the 915MHz range. Has anyone had experience with PCB antenna design and, if you have, do you prefer meandering or inverted F? Also, any references to help with design would be much appreciated!

New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? Thats where the smart machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show whats possible with smart machines, and what tradeoffs need to be made to implement such a solution.
