I would like any responses to be off-line for the following

     I made a simple mathematical model of a stripline, 1 inch trace, on 
     FR-4, nothing out of the ordinary as far as dimensions and found to my 
     surprise a resonant freq at about 800 MHz with a 20 to 40 dB roll-off 
     above 800 MHz
     
     Could someone in the RF/Microwave world of nuts and bolts pc board 
     design tell me what I'm supposed to do at say 10 GHz with regular pc 
     board materials/construction/fabrication???
     
     Thanks in advance, Doug McKean
