Please help me on this

[troi1]

im about to make a rf source circuit compromising
1. signal gen
2. amplifier
3. antenna (patch)

my plan is i will put the signal gen as source having a 868 MHz to the amplifier w/c is directly connected to the patch antenna and to be receive on the other side by a 1/4 quarter wave whip antenna having the same frequency as in the tx side
for tuning purposes....

my problem is im not that familiar in making a patch antenna by myself, i don't wanna buy either can u help me on designing it??

another is that what amplifier shall i use?? is just the typical rf amplifier???

and last will my system be possible to produce a very low ac voltage??


this is for my thesis so pls pls pls help me.... its a matter of graduating or not..:sad::sad::sad:

please please reply asap....

hi
what s u problem and what u want for help

 

[troi1]

hey... i would want to know how to compute for the parameters of a patch antenna having 868 MHz, for the big (ground) and small plates, both length and width, including the height of the dielectric, i find it hard to understand the context of some ref. materials including here on the net,

and i also need an amplifier circuit for an 868 Mhz input freq.

thank you... in advance

hi
i can't understand your problem about antenna and witch patch with which condition u want for u design ?
