high frequency Antenna design

[sundara]

what are all the important things to be taken care while designing high frequency antenna(300 GHz)?

 

[rfmw]

What kind of an antenna and what are your requirements?

 

[sundara]

patch antenna , above 300 GHz..

Thanks.

300 ghz really?

 

[jallem]

wow,300 GHz is very high............
no many people are working in that area.....

Tolerances, tolerances and tolerances. I have done antenna work to 200 GHz for a reflector system.

I am just curious to know that for what that 300GHz antenna will be used..it is infact upper end of radio spectrum..EHF..

The gap between high mm-wave band and far infrared is today a hot topic (0.1-10THz)!

Usually, if you have a single antenna, lens is the approach you should go for in case you need high-directivity antenna. One of (many) problems is the reflection on the lens-air interface.

EDIT:

"patch antenna" ... you mean planar antenna probably, right?

Again, the question is what are your requirements...

i think u shd go for lens antenna .. for a aptch antenna above 300ghz .. tyhe subs thickness will come in picometers.... thets are very tough to fabricate ..


can u specify for wht application u need this for ..

Hi Sundara,

What are you trying to accomplish?
