.... BeamForming (DBF) technique [7] In this technique the amplitude excitations are determined from [13] and the phases are found following the analysis in [23] Once the complex (amplitude and phase) excitations are known, the patterns can be found from the exact or approximate formulas in [24] [25]. These approximate formulas have been shown to work in a variety of practical modeling situations and are also simple to use [26] 28] To that end, the NEC BSC code [29] can be used which contains these approximate formulas. The NEC BSC code requires antennas to be off the cylinder curved ....

....to determine the complete pattern [3] 13] ignoring mutual coupling effects. It turned out convenient to use the NEC BSC code [29] that is ideally suited for such calculations. However the NEC BSC code does not allow the sources to be mounted on a cylinder due to limitations in its formulations [25], 26] It turned out from the analysis in [21] 22] that dipoles should be placed no less than 4 off the cylinder surface for engineering approximations. This has also been verified by comparing the NEC BSC and eigenfunction results and are presented in Appendix A. When the source is off the ....
