“…The synthesized directivity for different radiation pattern direction objectives: {0°<θ0<60° with Δθ=10°} and {0°<φ0<90° with Δφ=10°} of the reduced BFN array with MED and classical patch antenna [4] are presented in Fig. 12a and Fig.…”

“…From the classical antenna array theory [4], the amount of directivity is generally related to several factors such as the directivity of the radiating elements, the number of elements and the level of coupled energy into adjacent parasitic elements when dealing with parasitic arrays. However, when a classical wideband stacked patch antenna is used as radiating element, the coupled energy in the E Plane and H Plane are not equal.…”

In this paper, we propose an architecture of array based on parasitic element antennas with multiple excitations. The objective is to improve the directivity of these antenna arrays using Magneto-Electric Dipoles (MED). In this contribution, we consider a 49 (7 X 7) element array with only 8% of the elements directly fed. The others are fed by couplings and they are loaded on reactive values (ideally). The proposed radiating element is compared to a stacked patch design in the same reduced feed network configuration. A maximum directivity of 20 dBi is obtained, allowing several reconfigurable antenna scenarios based on such as design.

The objective of this paper is to design a parasitic antenna array capable of rejecting interfering signals and directing its main lobe towards the wanted signal. The designed antenna is a linear array consisting of an active monopole and fourteen parasitic monopoles. The method used is LMS, making it possible to calculate the values of the reactive loads to be connected to the ports of the parasitic elements so that the radiation patterns satisfies the fixed constraints. The simulation results in CST-MWS (Computer Simulation Tool Microwave Studio software) of the radiation patterns show an energy level of less than -0.71 dB in the direction of the interference and a gain greater than 5 dB in the direction of the wanted signal. Thus, this technique will make it possible to design directional antennas, with low energy consumption and interference rejection.
