I am considering using a Grandis SR42I010 ISM antenna in a design with a GND plane of 90mm x 25mm located above a metal (zinc) casting. I can provide a separation of approximately 10mm from the metal. What effect is the metal likely to have on the overall performance of the antenna? Is there anything I can do to optimize performance?
