Thanx a lot PlanarMetamaterials
Actually, I follow some paper their AMC larger than the patch antenna. i check as you mention by moving the antenna around to different locations on the surface (keeping the same distance to the AMC) but unfortunately still give negative gain
Even i try to...
Thanks a lot
Yes I am designing patch antenna, when I simulate it separately, it gives me positive gain but when I integrate it with AMC give me negative gain instead of improving it and reduce the backlobe .
AMC stand for artificial magnetic conductor surface that have two interesting...
Thanx a lot
I have tried anther AMC design and I integrated with antenna, still same problem negative gain
I attached the PIC of design
could you please suggest me to overcome this problem
if you need the cst file i will give you
Your cooperation is highly appreciated
Thanx a lot for your replay
Yes
I design the antenna and AMC separately at 2.4GHz, then I integrated them and I used foam with thickness of 1mm as spacer between them to avoid short circuit
when I simulate them using cst, the frequency is shifted as you mentioned. I tried to modified the...
Dear all,
I have designed simple microstrip antenna at 2.4GHz and I check its gain which has 1.488 dB when I integrate the antenna with AMC it gives me a negative gain
Do anybody had experienced such this problem or has idea to solve it can help me?
Thanks in advance
