rfsims — Thu, 31 Dec 2020 12:12:10 +0000

This component is a 1030MHz/1090MHz diplexer, i.e. splits incoming signals from a common port into two channels, dependent on frequency (1030MHz or 1090MHz). Each 1030Mhz/1090Mhz channel consists of a cavity filter of fourth order.

Narrowband Filter 20MHz Bandwidth at 1030MHz – HFSS Design

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.

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

admin — Fri, 16 Oct 2020 04:45:46 +0000

This file simulates a single Microstrip Patch Antenna at 10GHz in ANSYS HFSS. The patch is fed by a 50Ω microstrip line. 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:

Complete structure
Half structure using symmetry

X-band Pyramidal Horn with 21dB Gain at 10GHz – HFSS Design

admin — Fri, 15 May 2020 08:46:44 +0000

This item simulates the performance of a conventional pyramidal horn in ANSYS HFSS. The structure is simulated in X-band (8GHz~12GHz) and the realized gain of the antenna is 21dB at 10GHz. The input of the antenna is a standard WR-90 waveguide.

The simulation is fully parameterized and the user can change the parameters and optimize the antenna according to the user’s needs.

There are two simulation files: a) complete structure, b) quarter of the structure which uses E- and H- symmetry boundaries. The user can download the bundle which includes both of the simulation files.
