hey guys,
I'm designed a 1x16 rectangular array patch antenna on high frequency and I'm getting about 19 dBi gain. My problem is my azimuth beamwidth is very large "20 degrees" and I want to drop it down to 10 degrees.
I tried the following to reduce the azimuth angle:
1. increased the grounded plane and it didn't help.
2. increased the patch thickness and it helped a little but I cannot increase it more!
Any suggestions? please let me know.
P.S. my elevation beamwidth is good about 6 degrees!
Thanks,
Sam
