“…To simplify the calculations, it is essential to eliminate electromagnetic coupling between the sources and the radiating elements. According to the superposition theorem, the total field radiated by N elements at a point M, considered at great distance, is equal to the vector sum of the fields emitted by each source [13].…”

In this paper, a novel structure of antenna array which compose of H-shaped patch antennas with slot and parasitic elements has been presented and discussed. The proposed antenna is suitable for RFID (Radio Frequency Identification) applications. It is dedicated to operate in the frequency band centered on the resonance frequency f 0 = 2.45GHz. It is fed by a parallel linear array adapted to 50Ω. High Frequency Structural Simulator (HFSS) software is used to optimize geometric parameters and simulate the radiation characteristics of the proposed antenna array. The simulation results show that the reflection coefficient reaches a level of at least -31dB at the operating frequency of the antenna, a narrow bandwidth of the order of 26MHz, and a gain of 6.6dB.

Beamforming antennas are controlled electronically to adjust the radiation pattern following the first received signal. This allows the antenna to maximize the received signal and consequently, suppress the interfering signals received. A smart antenna should be able to diminish noise, increase the signal to noise ratio, and have better system competence. The adaptive beam makes use of the spacing of the several antennas and the phase of the signal of each antenna array to control the shape and direction of the signal beam. This paper focuses on the use of smart antennas using an adaptive beam method as a better system for the transmission of signals. A simulation between the existing Omnidirectional antenna system and the smart antenna system will be made and compared. The paper will discuss the corresponding advantages that a smart antenna system has compared to the Omnidirectional antenna system.</span></span>
