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!

Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the worlds biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sams Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesnt come from conventional, statistics-based tests but from accelerated stress testing.
Theres a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
