hi everybody,
I did HFSS simulation well with nVIDIA GT9800 graphic card. Expected that simulation time can be reduced, I've bought ASUS HD7850-DC2-2GD5 one. However, after installing new graphic card, HFSS starts up fail. It stands by splash screen then to be idle. I'm using Window 7 x64.
I...
Hi everyone,
I use Ansoft Designer V2.2 to simulate a small phased array antenna. It took me approximately 2 weeks to complete the simulation. However, when I created a report, S11, the simulation program had been stopping. It's loading data and standing there. I tried some times later, but...
hi Shahid78,
To optimize an antenna structure for any purpose, such as: Gain, Bandwidth, beamwidth..., I think first you should find out which parameters can strongly effect to your desired characteristic like parasitic elements, radiation element configuration... , for instance. Then you can...
I agree with Wlcsp.
I guess that you used high electric permitivity substrate and the proposed operating frequency is also high.
With a high electric permitivity, most of the CPW field (E & H) will be concentrate around G-S-G surface. In this case, I think you don't need to extend your wave port...
Does anyone have templates of Phased Array Antenna report or LATEX format for MSc graduation thesis? I need them!
Plz upload if you have any related document!
Thanks in advance!

Additional recommendation for you, the lumped port's impedance should be defined properly. For example, an opened two-wire line is feed with a 300 Ω lumped port.
regards!
The 3-port devices using microstrip structure also can be called: Power divider, Power spliter..
From what I'm thinking, you should better get some background knowledge for this kind of transmission line and its corresponding applications.
A good book, I think, that is "Microwave Engineering"...
Hi, I have several papers for you
1st one is "Synthesis of a compound T-junction for a two-way splitter with arbitrary power ratio"
2nd one is "The modified stepped waveguide T-junctions and the method of initial design"
3rd paper is "Design of unequal H-plane waveguide-power dividers for...
Most of present theories assume that the proposed microstrip antenna has a infinite ground plane then It will resonate at the length of λ/4. That's the reason why resizing ground plane size at a certain value causes the change of resonated frequency, I think.
