The antenna arrays which are composed of the combined-oscillator antennas are studied. The finite-difference time-domain method is used to simulate the radiation properties of the antenna arrays. The efficiency of feeding from the coaxial line to the antenna is calculated. The numerical results of the radiated fields and energy patterns for the single antenna, two- and four-element arrays are presented in this paper. The energy patterns for different configurations are compared. The numerical simulation results demonstrate that this kind of antenna array has the broad band characteristic and high feeding efficiency, and it can be used to radiate the ultrawide band electromagnetic pulse.
