ceramic material antenna

f = 1542 MHz +/- 1 MHz

size constraint is such that only have 1.28" x 1.28" x 0.05"
must be cp and have 'some' gain

i have found a couple ceramic materials with a dK of 20. with care a mpa is plausible and has been simulated. however the ceramic material is not plated. does anyone have any experience or knowledge of plating said material. or does anyone have an alternative idea they would like to discuss.

thanks in advance,

Is it for Industrial production or hobbistic / didactic purpose?

I suggest you 2 solution for hobbistic/didactic purpose:
1) Use Silver Paint varnish (avaible on RS catalog) and carefully draw the conductive circuit. The cable may be machanically secured by stronger glue (2 component resin).
2) Use the Copper Adhesive Tape (available on RS catalog) cut and form it and attach to the ceramic.
Because the tape glue is not strong, you may build a low er, plastic clamp between the 2 faces of the antenna. The Copper tape is thick, consider it on the simulation.
