Narrowband Filter 20MHz Bandwidth at 1090MHz – HFSS Design

admin — Mon, 14 Dec 2020 07:21:02 +0000

This item includes two designs of a narrowband filter with 20MHz bandwidth at 1090MHz in ANSYS HFSS. The inputs are 50Ω SMA connectors. The order of the filters is four.

The design 02 has a transmission zero at 1090MHz. The details of the simulation results are available in the attached pdf file.

These filters can be used in Identification Friend or Foe (IFF) or Secondary Surveillance Radar (SSR) systems.

admin — Sat, 05 Dec 2020 05:35:04 +0000

This item is a design of narrowband filter with 20MHz bandwidth at 1030MHz in ANSYS HFSS. The inputs are 50Ω SMA connectors. The order of the filter is four and its return loss is less than -15dB within 1022MHz to 1038MHz.

This filter can be used in Identification Friend or Foe (IFF) or Secondary Surveillance Radar (SSR) systems.

Coax Fed Microstrip Patch Antenna at 10GHz with Linear Polarization – HFSS Design

admin — Thu, 15 Oct 2020 04:13:38 +0000

This file simulates a single Microstrip Patch Antenna at 10GHz in ANSYS HFSS. The patch is fed by a 50Ω coaxial cable via an SMA connector. The substrate which the patch lies is Rogers 5880 with the thickness of 30mil.
The polarization of the antenna is linear.

X-Band Coax to Waveguide Adaptor – HFSS Design

admin — Wed, 30 Sep 2020 16:12:10 +0000

This item simulates a coax to waveguide adaptor in ANSYS HFSS. The structure is simulated in X-band (8GHz~12GHz). The coax connector is an SMA and the waveguide is WR-90.

There are four designs:

Design 01 which has a return loss of better than -12dB
Design 02 which has a return loss of better than -15dB
Design 03 which has a return loss of better than -23.5dB
Design 04 which has a return loss of better than -22.5dB

Designs 01 and 02 have two files:
