Is it impossible,using mm-wave microstrip array, to implement <=1.5 degree and <=-20dB SLL?
if it is ,and how to do ?
and Can some one give me some help or refference example?
Best regard!
I have got the Chebyshev current distribution about a line array with 32
how i can get the 2D radiation pattern
can some one give me an example like this ?
Re: 900MHz patch antenna
i think the patch size has little on antenna input impedance,for the port position and the port define has more effect on it.
maybe you should examine the antenna port more carefully.
this IRE paper is too old in 1961 ,causing i can't find it
the paper name is "sidelobe reduction by nonuniform element spacing"
can some one help me ?
thanks!
thanks a lot for both of your help !
and if i want to realize a square microstrip arrays with 64 cells,and what is the feed network ,i use chebyshev current distribution.
best regards!
Can some help me?
i want to design a 64 cells array,
the excitation i use is dolph-chebyshev current distribution.
However ,i don't know how to realize the feed network?
the array is square.
best regards!
hello,every one
how i evaluate the mutual coupling about large array,
and how can i simulate the array in HFSS or IE3D, if i think about the coupling
between array cells?
best regards!
