Hi,
Can anyone tell me what's the difference between differential antennas and unbalanced antennas in terms of disadvantages/advantages.
Some good links will help. Can't find anything on google...
Thanks for replying guys, but let me explain why the patch was shorted to the ground plane.
The quarter patch as its name suggests is smaller than the full patch, but by shorting it to the ground plane, it becomes electrically wider while maintaining a small physical dimension. At least that's...
varactor diode antenna
Hi, I was recently tasked to come up with a circuit diagram on how I would connect varactor diodes to my patch antenna so that I can tune the antenna electronically. I currently have 2 designs.
One is for a normal patch antenna in which the varactor diode is connected...
gamma matching antenna loop
my bad...my LCR meter can only measure up to a certain inductance value.
Manage to get my centre frequency at 13.56MHz after using a better LCR meter to do my measurements.
gamma matching
I am currently doing a project on RFID antenna design. Recently, i have been looking at doing GAMMA matching for my copper tape antenna. After being stuck at it for one week, i am still unable to get it right. Therefore, i would like to seek advice on anyone who has attempted...
