This paper shows that finite-difference time-domain (FDTD) analysis incorporating a graded grid may be used to accurately model a three-element triangular array of printed dipoles. Each element forms a complicated structure that combines the microstrip feedline, balun and dipole. Examples of an input response and an element coupling are presented for the range 2-14 GHz, together with far-field radiation patterns for one of the elements at a frequency of 9.3 GHz. All the results obtained by the FDTD model run on a low-powered HP 9000 series workstation are compared with measurements of the actual antenna array
