Hi guys,
I am designing a reflectarray. Now I want to calculate the required phase for each element in the array. I checked Dr. Pozar's paper:
D. M. Pozar and T. A. Metzler, "ANALYSIS OF A REFLECTARRAY ANTENNA USING MICROSTRIP PATCHES OF VARIABLE SIZE," ELECTRONICS LETTERS 75rh April 1993 Vol. 29 No. 8 .
In this paper Dr. Pozar gives a equation to calculate the required phase, please see the attached picture for the equation.
My question is: if I use the following units: frequency(GHz), wavelength(m) and Ri(m), then what the unit of the \[\phi\] should be?
I think the unit of \[\phi\] should be radians.
But the \[\phi\] value I calculated is like \[\phi\]=79.5. So it is 79.5 radians. I think the final \[\phi\] should be in the range of 0~\[\pi\]. So should I use \[\phi\]-2*\[\pi\]*N to get the \[\phi\] value into range 0~\[\pi\]? Here N is a proper integer.
Is my understanding right? Thanks a lot in advance.
