i had the same project, i tried a lot of designs but in my opinion the simplest way is to design a linear array with a series feed, tht gives a constant phase shift along the radiating elements and then for phase shifting u can vary the phase of input feed.
PM me ur email, ill mail u some...
here is another geometry for the phase shifting thing-can anyone make that on hfss?
how to make the curves and to add resistors? plz help
dimensions are attached, f=10ghz

i found a design regarding the phase shifter, its a hybrid coupler wich provide 90deg phase shift at the one output..
im attaching the schematic for the basic design, i want to know:
1) is it appropriate regarding the phase shifting thing.
2) can it be designed on the hfss
3) and will i need...
im doing this project on phased array antenna, i hav designed an array of 4-elemnts using the corporate feed method, but the problem is with the rectangular plot i.e im not getting the correct resonant freq dip..
im attching the hfss files for the single patch and the array, plz look at it and...
the problem is that, in our original design we had to add the active phase shifting components during the fabrication, but now we hav to simulate the phase shufting first.
any way of doing phase shiting in the hfss?
at khouly:
i mean wht is the best phase shifter, tht can easily be fabricated and varied?
another thing is, is there any possibility tht power divider circuit can change the phase as well?
specifications:
resonance frequncy is 2.4 ghz,
regular 50 ohms transmission line,
substrate height = 1.6mm
relative permitivity = 4.28
loss tangent of tan δ =0.016
iAM attaching the dimensions of the antenna, its the basic unit of the array, 2 units are attached together to form the 4 element...
my project is to design a microstrip phased array antenna in the microwave domain..ive designed the linear array of 4 elements and the power divider circuit nd now i have to convert it into the phased array...
i want to know the best way to do that..plzz help
nd if possible for anyone to...
they are taking tooo long to reply :(
one thing more i want to ask, what is the best way to convert the linear array into a phased array for software simulation?
thanks a lot man..
yea im also comparing the s11, and also the radiation pattern for the gain efficency changes..
what tool you are using? can u give me any link to download that software, hfss is really giving me the hard time :(
thanks a lot guys, ill try drawing it with the planes method.
problem in hand is to create a phased array antenna of 4-elements, and in this step im looking for the optimal array design, i came across this one in a book.
resonance frequncy is 2.4 ghz,
regular 50 ohms transmission line...
