Antenna Energy Patterns of Nonsinusoidal Waveforms

In this paper, energy patterns of antennas are derived for nonsinusoidal waves with different time variations. Some of the energy patterns for waveforms consisting of positive as well as negative values have a narrow beamwidth and drop to almost the zero value in the vicinity of the beam axis. Such features are desirable for good angular resolution. Energy or average-power patterns for waves consisting of one and two sinusoidal cycles are also derived and compared to that of an infinitely long sinusoidal wave with zero bandwidth.
