I need some help to decide about the way I'm designing the circuit to achieve the best antenna performance while meeting the 50ohms impedance for the transmission line, in the first example below, I made the line width 10.7 mil and the gap equal to 5 mil, on the second example, the line width changed to 13.8 when the gap increased to 8 mil, I can achieve the 50 ohms on both examples, knowing that I got the H, T and the ER values from the board house so I'm only focusing on the W and G widths, I'm designing for the frequency range of 700 MHz to 2.5 GHz, my questions:
1. Which way is preferred? increasing the line width or increasing the gap width?
2. I've been told that G value must be equal to H value, but I am not sure how true that is!
3. Does dielectric thickness H is important for the RF performance? is 4.3 mil acceptable? or should it be okay as long as I can design the circuit for the 50 ohms impedance?
Your help is highly appreciated.
