Since it is a microstrip array it is for low power applications. The desired performance for the different frequencies are a S11 of -10dB (that translates to some VSWR maximum but I'm on bed right now :(. So let's say the S11 graph would have multiple spots where S11 peaks down at -10dB (okay...

I think that's exactly what she wants. She wants the single antenna operating in versatile narrow bands for GPS jamming, ISM and some cm wavelengths I need to design one using rectangular microstrip antennas though. That's the thing with this project.

Oh thanks, I'll give those a read. By the way, is it possible to design a multiple frequency antenna using a simple miscrostrip feed line and different sized elements?

The university does have a VNA but that's only after I'm done simulating and drawing the design. I think my professor wants a 3x3 array with horizontal and vertical subarrays of 1x3. I'm not sure what he wants with that frequency range but anything near that is already fine. I've read a lot of...

Hello, I'm in the junior year of EE with a focus on comm. This might change anytime in the near future, though, I'm just trying to find my niche. Keeping this short, I hope I can help and get help from people around here. cheers, Enio

Hello, I'm currently engaged on a project where I need to design a 3x3 rectangular patch antenna array operating 1.5~5.8GHz on FR4 h=1.6mm substrate. I've studied the single element design and some TL matching techniques like the quarter wavelength but I can't put together a 3x3 elements...
