“…Using the set of Wiener Hopf equations with the stochastic gradient method, this developed procedure was later known as the least-mean-square (LMS) method. In Kong et al (2011) [13] The LMS algorithm is used to design the uniform linear array and rectangular planner array and then to prefer the method of designing heterotypic antenna. In this way, the size of the antenna is much smaller and the performance of the antenna is good in terms of system gaining and Signal to Interference Ratio (SIR).…”

Smart antenna system has been studied extensively for the fifth generation of wireless communication systems, because it has made a system better performance of higher capacity and coverage as well as of power-saving. The present paper introduces a design of planar microstrip patch antenna array for a smart mobile system operating at 28 GHz. The present smart antenna has an adaptive radiation pattern that adjusts its main beam automatically to the desired direction by following the signal environment. This is based on the processing of an algorithm called the Least Mean Square (LMS) resulting in a change in the magnitude and phase of the feeding current for each element in the antenna array. From the obtained results, the main beam can be steered 180 degrees in the phi (azimuth) plane at a constant theta (elevation) angle. The planar antenna array was designed and simulated using CST Microwave Studio and MATLAB software that is used to find the required exciting current for each element. It is found that the antenna bandwidth is greater than 1 GHz while its gain is about 21 dB.

“…It has great advantage in many fields, such as wireless communications systems and radar remote sensing, etc. [2]. Indoor applications are challenged by multipath propagation, and interferences are more likely to occur due to the large number of devices sharing a confined space.…”

“…Factors affecting performance of adaptive antenna include both the adaptive algorithm and the structure of the antenna array. To arrange the structure (number of elements, distance between feed points, pattern) of antenna array properly can improve the performance of the adaptive array [2]. The smart antenna system estimates the direction of arrival of the signal by using MUSIC algorithm which is subspace based technique.…”

This paper presents a dual-band planar antenna array for ISM band applications (2.4 GHz and 2.45 GHz). This antenna is proposed for indoor applications and enables adaptive beamforming and angle of arrival (AOA) estimation. An adaptive beamforming algorithm is applied for a planar antenna array, which is able to steer its main beam and nulls in azimuth and elevation planes over a wide frequency band. Planar antenna array operates as a spatial filter in 3D space, processing the received signals with weighting schemes. A planar antenna array is designed for AOA estimation in azimuth and elevation planes by using MUltiple SIgnal Classification (MUSIC) based on subspace algorithm. The Base Station (BS) equipped with this planar antenna is preferred to be at the center position on the room ceiling to cover all sectors of the room. It is designed to use four directional triangular elements arranged to form a square planar antenna array. Planar antenna with four elliptical slotted triangular elements (PAFESTE) is used to obtain optimal directivity in four directions in azimuth plane with specific orientation of 30˚ in elevation plane. It is characterized by half power beamwidth in elevation plane of about 60˚ and half power beamwidth in azimuth plane of about 90˚.

The consideration of smart antenna system using an 8x8 planar phased-array antenna offers the synthesis of a needed beam pattern which is not obtainable with a single patch antenna element. In this research work, a high performance planar phased-array antenna has been designed using an 8x8 square grid of z-controlled antenna monopoles with a length of 0.482λ. The considered element spacing is 0.315λ and the average directivity of 22.0 dBi. The uniform current distributions and binomial current distribution has been used for the design. To minimize the side lobe level characteristic to a lower one of -20 dB with reference to the main beam, the binomial current distribution is preferred for the work. This approach for the synthesis of antenna's beam pattern reduces multiple interferences by installing nulls in the course of signals interference and putting the central beam pattern in the track of the targeted signals in phase and amplitude regulation.
