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!

Some cars are more reliable than others, but even the vehicles at the bottom of this years Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
