ANSOFT Filter Solution
Microwave Filter Microwave Filter is a two-port network used to control the frequency response at a certain point in a microwave system by providing transmission at frequencies within the passband of the filter and attenuation in the stopband of the filter
Microstrip Filter
Dielectric Filter
Waveguide Filter
LTCC Filter
Key Point : Advanced Filter design needs to coco-simulate by circuit and 2D/3D Electromagnetc solver.
Ansoft Designer™ Filter Design Wizard Filter Design Tool is an interactive design utility for designing filters for high frequency RF and microwave applications. The capabilities of the Filter Design Tool include: • Design of ideal lumped element filters • Design of filters employing inverters • Design of coupled resonator bandpass filters • Design of transmission line filters • Design of coupled line filters • Design of combline, interdigital and hairpin bandpass filters • Design of waveguide bandpass filters • Design of filters having various approximations including Chebyshev, Bessel, etc. • Design of filters using stripline, microstrip, rectangular bars etc. • Application of simple individual element or circuit modifications • Application of network transformations • Exporting schematic and layout to Ansoft Designer desktop

Design Example : High Performance Cavity Filter Design 1. Define parameterized individual model in HFSS.
?S11 (d , ? ) S12 (d , ? ) ? ?S ( d , ? ) S (d , ? )? ? 21 22 ? S-parameters depend on frequency and aperture width. 2. Create the entire filter in Designer by importing from individual HFSS Design models.
The model is fully parameterized! 0
