Designing a 315 MHz antenna on flexible substrate!!!

Designing a 315 MHz antenna on flexible substrate!!!

Designing a 315 MHz antenna on flexible substrate!!!

I am currently playing around with ideas on designing a antenna on a flexible substrate like a copper foil. One side is a polystyrene and the other is a 1 oz copper cladding.

I have tried a quarter wavelength patch antenna. Basically a square with a short 1.25 cm long feed point from the RF circuit to the patch. If the outside dimensions is a quarter wave than it will fit in my housing.

Anyone try a slot antenna or possibly a circular patch design? Please do not limit yourself to these ideas.


RE: Designing a 315 MHz antenna on flexible substrate!!!

You can try to dielectically load the patch.  You can add a dielectic over the patch or select a different substrate.
Check out Roger Corp.(http://www.rogerscorporation.com/acm/index.htm)

You can also dielectrically load the gap of the slot antenna.
