I have made a capacitor on a teflon substrate which is just two 10 cm long parallel copper tracks with 5 mm spacing between them. When I connect Radiofrequency (<200 MHz) source to it , the electrical field is not uniform along the length of the capacitor. How could i make this field uniform?
Just curious, how do you know the field is non-uniform? is this a series cap or a shunt cap?
10cm is ~7% of a wavelength, 24 electrical degrees, I think there should not be much of a distributed effect. but you could try two 5cm line/pairs in parallel.... or five 2.5cm lines that have four uniform gaps...
