    Waveguide slotted antenna array

    Hello, I consider the following configuration for the array: two waveguide shunt resonant slotted subarrays of N=8 slots, placed longitudinally. I.e., both subarrays share the wall for the short circuit condition, and both subarrays are edge feeded. There is a symmetry plan across the short...

    multilayer PCB with high dielectric constant

    dielectric extremely high constant materials 2009 I try to replace alumina substrate (e=10). Freqs till 18GHz, at least till 6GHz. I've seen at LabTech Mw multilayer PCBs with RO3010 are possible. Thanks.

    multilayer PCB with high dielectric constant

    roger pcb material & dielectric constant I need a PCB with only the top layer of high dielectric constant. I didn't find a manufacturer for RO3010 top layer multilayer PCB. Could you recommend me one? I also consider the possibility of mounting some alumina pieces on top/in the middle the PTFE...

    multilayer PCB with high dielectric constant

    pcb dielectric constant; I've seen RO3010 with e=10.2 at Rogers. Many manufacturers employ ROXXXX for high freq pcb-s. RO3010 wouldn't be a possible option? Thank a lot again.

    multilayer PCB with high dielectric constant

    pcb dielectric constant Hi, I would like to know if a multilayer PCB with a high dielectric constant (e=10) and low losses at high frequencies is possible to manufacture. Thanks a lot.
