Return Loss Calculator
Calculates the absolute load impedance, reflection coefficient, VSWR, return loss and mismatch loss of a load

Single Layer Air Core Inductor Design
Round wire coil with dimensions and current-sheet approximation

Sophisticated Helix Antenna Design
With matching Coax to 50 ohm<

The Quarter-wave stub
The Quarter-wave stub can be used for many purposes. If it is left with an open end it can be used as a notch filter to attenuate certain frequencies
