Hello, I am a student studying in Korea. beginner..
I need your help..!
Prob. 11.3-2 : A linear array of four quarter-wave microstrip patches spaced 4.2cm apart are to be excited to produce an endfire beam. The operating frequency is 2.73GHz and the substrate relative dielectric constant is 2.45. Sketch the corporate feed network required to accomplish this, indicating on it the extra microstrip transmission line lengths in cm required for porper phasing.
And,,,
Square Microstrip Patch Antenna,,
f = 3.03GHz, t = 0.114cm, er = 2.35, L=W=0.49*(ramda/sqrt(er)) = 0.49*(9.9/sqrt(2.35))=3.165cm
Q: Estimate the directivity.
And,, I have a lot of questions... TT
but thats it for now..
