Using the Estimate Module

T-Line

Estimates transmission-line quantities such as the characteristic impedance of a line, the line width corresponding to a characteristic impedance, the guided wavelength and the effective relative permittivity of a microstrip line or stripline, and the losses associated with a line.

Impedance Match

Estimates the dimensions of a quarter-wave section to match a load impedance to an input impedance. Also estimates the location and dimension of a tuning stub for matching an input impedance to a complex load impedance.

Printed Antennas

Estimates the dimensions of patch antennas.

Microwave Calculator

Converts between the mismatch loss, the reflection coefficient, the return loss, and the voltage standing wave ratio (VSWR). Also converts between dB and the ratio for both power and voltage values.

Units

Sets the current working units.
