From (14) and (15), we derived approximate analytic expressions for the total axial current based on the King's three-term approximation for imperfectly conducting and loaded receiving cylindrical antenna as [17,18]
Figure 5 shows a cylindrical antenna array with 4 rings of 16-element array mounted on the cylindrical surface.
Various methods similar to those used for the circular conducting slotted antenna were employed in the two-dimensional (2-D) and three dimensional cases to obtain different radiation characteristics of the dielectric-coated slotted cylindrical antenna [6-8].
An adaptive, phase-only genetic algorithm applied to a computer model of a linear array has been reported previously.(6) This article extends the previous work to amplitude and phase nulling on an experimental cylindrical antenna array.
The constitutive and the geometrical parameters of the planar microstrip antenna and the above-considered cylindrical antenna are the same, with the geometrical dimension [W.sub.str] = [L.sub.u] = 0.129 cm added.
In order to well exploit the vertical angular resolution of signal propagation, different kinds of the antenna array configurations, such as the rectangular, spherical, and cylindrical antenna array deployments, have been studied in 3GPP [13-15].
In [12], the DGF approach to FDTD simulations was demonstrated in the design process of the ultra-wideband cylindrical antenna. This technique employs the DGF as the ABC placed close to the antenna surface and as the radiated field propagator to observation points at each FDTD iteration step.
