What is the antenna on my new passport for?

The little booklet explains the chip, but nothing about the antenna.

Thanks in advance, just curious.

It so the aliens can read your brain waves a little easier. A collander wrapped in aluminium foil worn on yer head will help ;) ;)

Seriously though, I found this:

RFID chips consist of a microchip and a tiny antenna that transmits data from the chip to a reader. The reader is activated whenever the antenna comes into range and the data can be used to trigger an event – such as ringing up a purchase, ordering more stock or, in this case, providing identification details to border control officials
