Microstrip Patch arrays design
wireless aplications. I am using IE3D software to simulate the array. I need that the array
has 19 dbi of gain, ROE < 1.4 and a smoller front to back lobule.
I don′t know how to calculate the finite ground plane, its dimension. I am using array of 16
patch antenna. I want to know to how to calculate the optimal feed point for the array.
any idea?
Some features of the antenna are:
f=2.412GHz
dielectric constant=4.4
metalic layer:copper
hight sustrate: 0.78mm
Thanks for your help.-
dear oggi :
i am also a newbie in antenna modeling designe .
i didnt use ie3d to simulate antenna arrays ,but i know cst 5 have some examples of arrays .
but i don;t how to control the parameters such as gain or others . do you have some refencenes about array design with software ?
my email is : fanqikai@163.com
thanks
Hi,
very good books for Antenna design & modeling are
1. CAD of Microstrip Antennas for Wireless Applications
by Robert A. Sainati
and
2. Compact and Broadband Microstrip Antennas
by Kin-Lu-Wong, A Wiley Interscience Publication
if need any of the above....
Eear Manjunatha_hv:
is there electrical books of above two ?
try to simulation the antenna factor....
you can tune the distance between the elements and phase difference or reading the antenna book to calculate the distance...
Hi, Oggi: I would suggest you to try to optimize your element and 4-patch array using infinite ground plane first. Input impedance is normally not affected by the size and shape of the antenna much. You can optimize it to get good match first. IE3D has built-in optimizers to help you optimize antenna perforamnces (S11, Z, or even pattern parameters). To defining pattern parameteres as optimization goals, you should try to enable pattern calculation in Optimization Setup first. Then, you can choose many of antenna's properties as goals. After you get the matchiing etc. optimized, you can build the finite ground plane model to improve the pattern. It normally takes much more time to simulate and optimize the finite ground plane model than the infinite ground plane model.
