AWR Microwave Office for antenna analysis

[apeeet]

1. Is correct to analize antenna's (patch) parameters, such as S11 and radiation pattern, with AWR Microwave Office? I'm wondering becose this tool very rarely mentioned among Electromagnetic Simulators.
2. What type of solver is used in AWR MO?

Hello Apeeet,

Yes, you can use AWR Microwave Office (MWO) for Planar Patch Antenna Design & Analysis for S11, VSWR, Input impedance, Radiation Patterns, Axial Ratio, etc...
AWR has two 3D-planar EM Simulators EMSight & Axiem both are based on Method of Moments (MOM) solvers...
There are good number of patch antenna examples available at AWR installation folder such as SpiralLog Periodic, Patch, Fractal, etc...

AWR Microwave Office is not an EM tool, it is a complete RF design framework with schematic entry, model based circuit simulator and layout.
Depending on the license, Microwave Office also includes EM simulation options (AWR EMSight, AWR Axiem)

EMSight is a closed boundary MOM simulator, similar to Sonnet. This approach is not ideal for far field antennae analysis, but can be suitable for basic patches and matching the antennae (S11) or designing feed structures.

AXIEM is an open boundary MoM solver, which is ideal for all planar antennae analysis including far field patterns. This is a relatively new product (2008), so the literature on it is not so extensive, but the feedback is quite positive compared to ADS and/or Zeland. It is quite capable of doing very large antennae arrays since it can handle a large number of unknowns by virtue of NlogN scaling from iterative matrix solvers.

you can calculate s-parameter in microwave office, awr use method of moment

The best tools in business are CST, Empire 3D, FEKO and HFSS

These are 3D volume meshing tools. They are good for some analysis, but not the best for everything.
For planar analysis (PCB, LTCC, RFIC) the planar Method of Moment solvers like Sonnet and Momentum also have advantages.

True but CST 2011 and Empire 3D has Moment Solvers now

True but CST 2011 and Empire 3D has Moment Solvers now

1. Empire is FDTD and does not use MoM.
2. CST might have MoM solver, but that 3D MoM would be much different from planar MoM.
3. The strength in the planar MoM solvers is their handling of calibrated ports etc. The concepts in the 3D solvers are much different, even if they use MoM.

The new Empire 3D has an option of MOM

Can you show me a link with more details?

Its basically an update developed by some one from IIT Madras

Never heard of that. Btw, I am part of the Empire team.

Great Sir.

Nice to know you. Basically I am a RF designer working on all analog, DSP and antennas and help DARPA and DRDO for military apps

 

[volker_muehlhaus]

That's great, but have you looked at the antenna types used in cars?
I have supported automative companies with their car antenna designs, and not seen patch antennas in automative applications yet.

(Sorry, this answer belongs to a different thread)

Yeah but this has been developed and applied for patent.
