Hi
People i need some help and papers with an antenna design
I am looking for an antenna with 14% bandwith using slots or stacked patches, aperture coupling or any other succesful method to increase the bandwith. The dimensions should be less than 4cm*4cm
The Frequency should satisfy the...
Re: patch antenna
Dear badseed
I have an antenna with 40% bandwidth using air substrate. The shape of the antenna is an E-shape and the air thickness is 14mm. The total dimension of the patch is 105mm by 45mm
If ull interested i can give u the paper.
I am designing my self an antenna with...
hi
I am trying to design a microstrip slot antenna. Their is method to reduce the size of the antenna by inserting slots to the ground plane. Does anyone know how can this be achieved using Advanced Design System by HP?
thanks in advance
Bobby
It is for my dissertation. Actually i met my supervisor today , this antenna has been designed by Nokia and operates from 1.95 GHz to 2.1 GHz. The dimensions of the antenna have to be reduced to minimum so it can be fitted to the handset. The bandwidth has to be achieved without air gaps. He...
No
I achieved 40% bandwidth with an air gap of 14mm and antenna dimensions 105mm,40mm
The next step is to minimize the antenna, and instead of air substrate to use a supplied substrate with the specification mentioned before. The bandwidth target will be 14% for the new antenna.
There will be no air gaps in the design. I need overall bandwidth with respect to the centre freguency around 13-14%.
return loss <-10 dB
I need the antenna to cover the frequency spectrum of UMTS from 1.825 to 2.1 - 2.2 GHz
VSWR<2
regards
Hi Marti
The dimension of the patch should be around 40mm for width and lenght
The thickness h=1.524 but if using stacked patches can get up to 3*1.524 when using three layer.
U see i have to use Duroid with Er = 2.5 and h=1.524.
But any paper for any broadband design could be useful
cheers
Hi Everyone
I am looking for some help to design a broadband antenna. I designed an E shaped antenna with 40% bandwidth using air substrate.. I am trying to design a miniturized broadband microstrip antenna from 1.9 GHz to 2.2-2.3 GHz using stacked patches or single layer E-shape. I am also...
