Even and odd mode impedances of a coupled microstrip line. actually I find the reason when you use differential port, the impedance you get is twice the odd mode impedance, whereas if you use common port, the impedance is half the even mode impedance. 1 members found this post helpful.
Odd Number-A number which can NOT be divided by 2 evenly. Whether A number is even or odd-can be found by looking at its last digit. Numbers that end with digit of 2, 4, 6, 8 or 0; are even numbers. Ex. 24, 34, 58, 80. Numbers that end with digit of 1, 3, 5, 7 or 9; are odd numbers. Ex. 23, 35, 57, 89. Even Number-An number when divided by 2 gives another whole number.
