[Moved]: RF 50 ohm PCB trace width | Forum for Electronics.

When doing boards with a thin dielectic on the top layer which makes for a thin 50 ohm line, if the pad for the SMA edge launch pin needs to be wider, you can eliminate ground directly under the pin pad to increase the dielectric thickness. I'll calculate what the pin pad width will be (to get 50 ohms) if the ground is on layer 3, or 4, or 5. I'm referring to the characteristic impedance of the trace itself) Using a few online calculators, with a thickness of 1 oz/ft^2, trace width of 50 mil, height of 63 mil, and dielectric of 4.3, (my understanding is that those are the characteristics of the reference designs), I'm getting an impedance of ~80 ohms for the antenna.

This page details the PCB Editor's Width design rule – which defines the width of tracks placed on the copper (signal) layers. Covers constraints, application and tips for working with this rule… (default = 50 ohms)…. Default equations are in place to calculate the impedance and the required trace width in order to satisfy that impedance. Different board materials, the dielectric layer thicknesses and constant (Dk), and the thickness of the metal traces all need to be part of the calculations. There are many factors that go into calculating the width of an impedance controlled trace. This means that the actual trace width for a 50 ohm line could vary from design to design. I used some online calculator to calculate parameters of trace so it has 50 Ohm impedance. I use FR-4, so H=1.5mm, T=0.035mm and Er = 4.5. 2-side PCB, one side with signals, the other with GND.
