Hi @ all,
I'm new to the subject UWB Antenna Design.
Whats the best starting point to create a small, directed, wideband patch Antenna with a short Impulse Response?
1.) How can I influence the Impulse Response of the Antenna to shorten it?
2.) Whats the best Way to match the Antenna impedance to the 50Ohm Cable Impedance?
2.1) Is a symmetric connection better?
3.) Is there any possibilty to get a better directivity (beamwidth) of the Patch (i tried Absorber at the backside but in the front direction i have not so much room)
4.) I need a frequency range from 500MHz to 5GHz any sugesstions for good good shape. At this time I'm using ellyptical patches which have a frequency range from 1.2Ghz to 3.5GHz but they have a bad directivity and long Impulse Response
Hope anyone has some suggestions
Ciao
