I need help in shortening the length of the microstrip line.
Supposingly I need to have a microstrip line which give me a 8ns of delay in the 300MHz frequency. Then I will need to have a very long microstrip line to obtain that.
Any ways or methods that I could use to shorten the length while maintaining the 8ns delay?
Use Germanium material, with Er=16, then 8ns=2.4T at 300MHz, substrate H is 2mm, 1/2oz for copper, so the length is 758.119mm. You can turn around it in the PCB.

Use some similiar phase shifter circuit: input port shunt L=3.54nH and C=79.27pF both to GND, then after a 10mm microstrip line, then L and C with same value both shunt to GND again. Substrate RO4350B with 10mil/0.5oz.
Thanks tony_lth... meaning we can simply meander the lines as long as the lines far enough each other so that no interference occurs. Usually how far/space should be between adjacent lines?
