Hello everyone,
I'm designing a printed high-power, high gain printed antenna array at appx. 1.7 GHz. I'm thinking an appropriately sized curtain quad or dipole array (backed with foam and a reflector) will work best to achieve >25 dBi of gain, but it needs to withstand 250W+ of CW input.
What material would be best suited for this application, and at what thickness? A curtain quad is only single-sided (i.e. no ground plane directly below), so I'm leaning towards 0.010" or 0.020" thick fiberglass (e.g. FR4). But, perhaps I'd be better off with the new RT durioid 6035HTC high-power laminate.
Any suggestions from folks that have designed high-power printed antenna arrays are welcome.
