oc i dont see any reference to you considering so called "fractal patch antenna" to also allow MIMO in the reduced space https://docs.google.com/viewer?url=http%3A%2F%2Fwww.urel.feec.vutbr.cz%2Fra2008%2Farchive%2Fra2005%2Fpapers%2F215.pdf and also make a separate wireless power circuit as well as these cap's etc fractal's are good for lots of things it seems, especially as you shrink down to save costs and open new markets :D https://docs.google.com/viewer?url=http%3A%2F%2Fwww.jpier.org%2FPIERL%2Fpierl06%2F08.08121309.pdf getting product ready for mass production in a timely manor seem like a larger challenge today

HAVE YOU THOUGHT ABOUT OR LOOKED INTO THE BATTERY ic OPTIONS? Cymbet is one company that comes to mind. I can't remember if they are the IC type or a just a thin membrane type. If this could be integrated under the shield or on the bottom of the package below the die.

The dual-resonator tank is implemented using spiral integrated inductors and MIM caps. Note the patch antenna is a separate module.

The achieved bitrate is ~20kbps. Note that if we replace the battery is replaced with a power supply, we can get 10Mbps. However, we need to re-charge the local storage caps before transmitting each bit

How is the dual tank implemented in the example when using the patch antenna as the L in a LC tank? do you use the FLL resonance rectified amplitude to compare with the modulated signal to determine frequency or phase shift?

How is the clock mantained when the antenna-tank oscillator is turned off? does it not keep a lock? does it have to re-aquire the freq lock?

Trick will be getting the MIMO to fit on the chip I suppose.

At 60 GHz this will be able to be beem formed with mimo extending range by orders of magnitude. since each radio in a mesh will be spacially located then these mimo equiped mini radios can be optimized for a given mesh layout for reliable power levels for R&T but have the minimum possible power used for transmission and the best SNR for recieve.

Wow! quite interesting that strategy of using several capacitors to get the extra current required for achieving a proper range in the uplink specially considering the size of the system. Though, 60 GHz doesn't appear to be compatible with the current PAN radio technologies like Bluetooth or upcoming NFC. Will this start the search for a new standard? No mention of the achieved bit rate? is it that slow?!
