- Analyzing large phased array antennas using time domain codes is favourable when looking into wideband solutions. This is often done by assuming an infinite array, i.e. a unit cell approach is used. Unfortunately, unit cell based time domain codes using time shifts between cell boundaries have a disadvantage of only being able of analyzing phase shifts corresponding to a beam scanned in the visible space. However, in order to fully characterize the infinite array antenna it is sometimes necessary to compute the active reflection coefficient also for scan directions/phase shifts corresponding to invisible space. Presented in this letter is a new approach on how to do this in a simple manner using unit cell based time domain codes. By extending the size of the computational domain, and include more than one element, phase shifts corresponding to invisible space are included.
