Abstract:

In the microstrip circuit,corners cause discontinuity,which in turn forms reactance in the circuit,thus the parasitic coupling.In engineering,chamfered microstrip line or sweep are usually adopted to directly compensate the discontinuity.This article uses a linear variable to simulate in Ansoft HFSS the different sizes of the cut angle and sweep,and quantitatively analyzes their advantages and disadvantages by their effects on discontinuity compensation.

Key words: microstrip line discontinuity;chamfered elbow;sweep elbow;HFSS optimization simulation
