For those who have worked on designin antenna arrays.....

I need help regarding my final year project for designing an antenna array. i need the diagram.

 

It looks like this: Two antennas separated by some distance and a splitter/combiner. The rest is left as an exercise for the student.

 

Antennas have different sizes related to frequency. That would be improtant to keep in mind.

 

what frequency is the antenna to be used at, and what bandwidth is needed? How much room do you have if it is a lower frequency design? Is it for transmission and reception or only for reception? There are many factors that are needed to design a good antenna, one good place to start would be a google search for ARRL, amateur radio is a great source of antenna fundamentals and designs.

 

I recommend reading this book :
"Antenna Theory and Design" by Stutzman & Thiele chapter 3. You can find everything to know about antenna array in the book.
