Modelling of microstrip antennas on a finite ground plane using the 2D physical optics model

Abstract

A method for the computation of radiation patterns of microstrip antennas on a finite ground plane is presented. The method is based on the geometrical theory of diffraction and the 2D physical optics model. The diffraction of space waves and surface waves is taken into consideration. © 2004 Wiley Periodicals, Inc.

High Gain Array of Monopoles-Coupled Antennas for Wireless Applications

“…The array of monopoles is positioned on a limited ground plane. In the limited ground plane size case, the well-known scattering effects on the ground plane edges alter the radiation pattern [7][8][9] (Figure 3). First of all, the interferences induce maxima and minima field on the radiation pattern.…”

Low-Profile Array of Wire Patch Antennas

“…These values correspond to the size of support which will be positioned under the final WPA array. In the limited ground plane size case, the well-known scattering effects on the ground plane edges alter the radiation pattern [10,11,17] (Figure 7). First of all, the interferences induce maxima and minima field on the radiation pattern.…”

“…(iii) The structure must be tilted to give back the main beam deviation caused by scattering at the ground plane edges [10,11,17]. The tilt angle that depends on the ground plane dimensions is adjusted a posteriori.…”
