GSM/DCS microstrip antenna help
(OP)
I'm trying to design GSM/DCS patch antenna. I would like some help? I use Sonnet for simulation.
My configuration is:
FR4 PCB , thinkness 1.6 mm
Available area about 30 X 10 mm
Could you give me advice to design a small patch antenna ?
thanks in advance

Seems to be a lot of patch antenna questions on the board lately... I wonder if it's senior class final design time at universities...

Does anybody have a shematic or a design sample ?
Thanks in advance.

I'd suggest a double stacked patch.
The IEEE is the place to get all the info you need.
If you are a member, you can buy their two DVD set which has 100+ patch designs in it.

I have a small place available (30 X 12 mm) and the total PCB size is 55 X 35 mm. I have no constraint regarding SAR.
My antenna must cover GSM/DCS bands (880 to 960 MHz & 1710 to 1880). My substrat is a FR4 PCB.
Do you have a SONNET exemple ?
Thank you
Best regards

RE: GSM/DCS microstrip antenna help
sounds like you need HFSS or IE3D or Microwave Studio for this design.
The bandwidths chosen are large and hence this is a difficult patch design, not a simple one as you request. You are pushing the edge of patch design with 8-10% bandwidths spaced 2:1 in frequency.
I just perused my IEEE patch design articles and saw nothing of what you need. There are alot of dual frequency designs with 2-5% bandwidths each though.
If you research available antennas and can find a patch covering those two bandwidths then you'll have hope. Otherwise, you've chosen a very difficult requirement for a patch and a very easy requirement for a notch antenna.
You may want to shift your thinking before you burn alot of design money.
