I am new to hfss. I want to do my final year project in uwb antenna design using hfss 11.please help me to design an antenna.I attached my base paper.

Hello,

Some things to consider before starting the actual design and simulation:

Frequency range
Acceptable VSWR – Return Loss within the required frequency range
Directivity
Dependency of directivity on frequency.
Radiation efficiency
Gain
Polarization
Maximum size
2D or 3D shape allowed
Allowable dispersion (depends on system requirements)

Designing wide band antennas is (always) a compromise. Small, wide bandwidth and good radiation efficiency don't go together.

Hi abinaya,

You want to design omnidirectional or Directional UWB antenna ?

hi,
Well then its not a big deal. you can easily design an omnidirectional UWB antenna which covers the entire UWB frequency range from 3.1-10.6 GHz. For example you can have a look at Circular patch antennas,Bow-tie antennas,circular fractal monopole antenna,quasi-selfcomplimentary-UWB antenna etc....all these antennnas are UWB omnidirectional antennas.

They have simple Geometry and very easy to build and simulate in HFSS.

how about designing an uwb antenna in lower frequency range (UHF range), is it as easy as designing in 3.1-10.6 Ghz?
 

omni directional UWB at 3.1-10.6 very easy but at low frequency it has some hardship for more information about UHF log priodic antenna u can see the A-info website
 
this software calculate LPDA antenna for u and you and simulated in hfss after calculate with this software

sir ferdows, thanks alot for this program, it's give me an option to use LPDA, as a Ultrawide band one
