摘要：

Measurements of the transmission/frequency responses of slot arrays embedded centrally in dielectric layers of various thicknesses show an inverse relationship between the 6dB width of the transmission band and passband loss. For epsilon(r) = 4.6, tan delta = 0.02 the losses exceed 1 dB for bandwidths below about 25%. A computer model identifies absorption in the dielectric as the main source of the loss.
