“…Among the various beam-steering techniques, switched beam networks have been highlighted because of the advantages of low cost, simple implementation, and low power consumption. The Butler matrix is one of the switched beam networks and is especially popular due to its simpler structure and wider bandwidth [3][4][5][6][7][8][9][10][11][12].…”

A beam-steerable dual-circularly polarized 60 GHz antenna array is proposed. A 1 × 4 dual-fed stacked patch antenna array is integrated with an 8 × 8 Butler matrix. By utilizing the 8 × 8 Butler matrix, the proposed antenna array generates dual-circular polarization with beam-steering capability. The proposed antenna array system demonstrates good reflection coefficients in the frequency band ranging from 55.3 GHz to 64.9 GHz and has a mutual coupling of less than −10 dB over the frequency range of 57.5 GHz–63.2 GHz. At 60 GHz, the maximum gains and beam-steering angles for input ports 2, 4, 5, and 7 are 9.39 dBi at −38°, 10.67 dBi at −11°, 10.63 dBi at +11°, and 9.38 dBi at +39°, respectively. It is also demonstrated that the dual-polarization is well formed by switching the excitation ports. The right-handed circular polarization (RHCP) is formed when four ports from port 1 to port 4 are excited and left-handed circular polarization (LHCP) is formed when four ports from port 5 to port 8 are excited. The proposed antenna array system could be a good candidate for millimeter-wave 5G applications that require wide beam coverage and polarization diversity.

“…The concept topology of the MIMO-DCT design has been a major research area in the past few years [4,5]. To change the beam in several angles, the most suitable approach is using a switched beam system [6][7][8][9]. The switched beam approach plays an important role in transmitting and receiving modes by subdividing the entire array antenna into micro-sectors to improve the capacity during the transmitting mode and point the main beam to the optimal direction at the receiving mode.…”

Abstract-Due to the increase in the data rates for modern wireless communications and recent generation standards, the switched beam approach and multiple-input multiple-output (MIMO) direct conversion transceiver (MIMO-DCT) have become promising techniques to satisfy these requirements. The combining of switched beam and MIMO-DCT through the use of multiple antenna elements has been investigated to overcome the high complexity and high spatial directivity of the conventional system. In this paper, a low cost miniaturized beam-switching array antenna with a MIMO-DCT system has been proposed, designed and analysed. The entire proposed system structure has two design stages. The first is the design of MIMO-DCT via the integration of microstrip antenna element, hybrid coupler, Wilkinson power divider and single-pole double-throw (SPDT) transmitter/receiver (T/R) switch. The second has the switched beam array antenna design using a Butler matrix feeding network and four distributed subarrays (DSs) of the MIMO-DCT. The entire proposed design structure components have been optimized using a commercial software to evaluate each component and meet the desired performance. The final proposed two-stage design has been fabricated, integrated, and the radiation characteristics have been demonstrated, using the Agilent FieldFox network analyser, to meet the requirements for LTE and wireless communication applications.
