pcb gsm antenna
I want to lay a GSM/DCS antenna directly to PCB.
So the size of it should not be too large.
Attachment is my design.
(red is top view, blue is bottom view)
The resonate frequency is just tunable, and can be the point I want.
But the bandwidth is too narrow.
What sould I do next ?
Any other desing ?
Thank U.
I have designed the IFA successfully for Bluetooth.
But the GSM&DCS frquency is too much lower than Bluetooth.
So, I think, the size maybe too large.
Is there any method to desing small IFA for GSM&DCS ?
Thank U.
