On the Radial Component of the Electric Field for a Monopole Phased Array Antenna Focused in the Near Zone
Abstract
The near-zone radial and principal spherical components of the electric field for a linear phased array antenna that is focused at one to two aperture diameters in the near zone are investigated. The phased array antenna, consisting of thin monopole elements, is analyzed by using the method of moments. A theoretical formulation is described and computer simulation results are presented. The results show that the radial component is negligible in the focused near-field region, which allows the principal component to be accurately computed from knowledge of only the tangential electric field on the focal plane. near-field focusing, method of moments, antenna testing. radial electric field component, focal plane, monopole phased array, near-field radiation pattern.
