We assume that there is a metallic

cylindrical antenna of radius a which transmits the plane electromagnetic waves in the radial direction.

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.
