What should be the size of an NFC antenna given an operating distance?

I am dealing with a project about a PCB with NFC antenna. We are designing PCB now. Do anyone know about the size of an NFC antenna if we want it operate in 10 centimeters?

NFC Type 4 can operate within a distance of 10 centimeters. NFC, which is compatible with ISO 15693 that is capable of NFC phones, can operate within a distance of 100 centimeters.

What is the difference between thin film and thick film precision surface mount resistors?

I’m using some 0.1% precision 10k and 150k resistors. They are thin film 0603 surface mount. For a lot more, there are also thick film types. Fundamentally and practically, what is the difference between these two?

Can I make a PCB without a ground plane?

Recently we are developing a portable device which should be very tiny and light. In terms of PCB design, I am thinking whether it is a good idea to exclude ground plane to minimize the product size.

Is it OK to bend a VIA in a Flex PBC?

On a Flex Printed Circuit (FPC) made out of Kapton polyimide, will anything bad happen if I put a VIA in a part of the FPC that has to bend? VIA size: 0.2 mm hole diameter in 0.4 mm copper diameter. FPC bend radius: 0.7 mm. Kapton thickness: 0.2 mm. Copper weight: either 2 oz or 1 oz (I haven’t decided yet)
