“…These lenses can be used for many applications such as multi-beam wireless communication systems in military [12][13][14][15]. With the development of fabrication technologies, numerous Rotman lens designs have been developed employing different techniques including microstrip [2,[5][6][7][8], graded dielectric substrates [16] or substrate integrated waveguides [17][18][19][20][21][22][23][24]. However, these designs still have a planar structure with a large electrical size which makes it difficult to integrate them into modern devices such as smart watches, mobile phones, curved TVs, or GPS devices, etc.…”

Abstract-The development of modern communication devices for the latest technologies such as 5G has brought the millimeter wave technology into the spotlight because it offers higher data rates and bandwidth. Since highly directional transmissions are necessary for communication in these frequencies due to high path loss and atmospheric absorption, the use of adaptive antennas is inevitable. Rotman lenses have long been used as analog beam forming networks to support linear array antennas for electronic scanning. Their broad bandwidth and planar structure make them ideal for a variety of applications. However, their overall dimensions can be prohibitive especially for large scan angles. In this paper, we propose a few compact configurations that reduce the overall dimensions of Rotman lens as much as 50% without degrading its performance.

“…The class of travelling-wave and leaky-wave antennas has emerged as a promising candidate for directive radiation emission from low profile conformable structures with simple feeding network [13][14][15][16][17]. These antennas offer significant complexity, cost and volume advantages for mm-wave sensing and communications applications when compared to phased arrays or reflector antenna architectures [18].…”

This paper proposes a hybrid scanning antenna architecture for applications in mmwave intelligent mobile sensing and communications. We experimentally demonstrate suitable Wband leaky-wave antenna prototypes in substrate integrated waveguide (SIW) technology. Three SIW antennas have been designed that within a 6.5% fractional bandwidth provide beam scanning over three adjacent angular sectors. Prototypes have been fabricated and their performance has been experimentally evaluated. The measured radiation patterns have shown three frequency scanning beams covering angles from 11 to 56 degrees with beamwidth of 10±3 degrees within the 88-94GHz frequency range.Keywords Millimeter-wave mobile sensing and communications· W-band antennas· Leaky wave antennas·

“…The amplitude and phase distributions are typically imposed by using beam-forming networks (BFNs). The important classes of these multiple beamforming networks such as Butler Matrix (circuit-based beamformer), Rotman Lens (lens-based beamformer), and integrated reflector systems form microwave passive networks [1][2][3][4][5]. The Rotman Lens is an attractive beamforming network due to its low cost, reliability, simplicity, and wide angle scanning capabilities [6][7][8][9], whereas the most popular circuit-based BFNs are Blass, Nolen, and Butler matrix [10][11][12].…”

Abstract-In this paper a compact two-layer microstrip passive beam-forming matrix in the 2.9-3.1 GHz frequency band is designed, fabricated, and measured. This 13 × 6 matrix is a passive circuit that can transform the 13 patterns of an antenna array into six possible beams to decrease the complexity for multiplexing/demultiplexing operation in three dimensional Radar. The 90 degrees hybrid couplers with high isolation between two signals and phase shifters between the couplers are used to provide proper signals in outputs. The matrix structure consists of metal walls around transmission lines to eliminate the surface waves. Also, a coaxial to microstrip transition is used to extract accurate measurement results. A special box is designed to cover matrix which has many design considerations such as cutoff frequency, destructive effects on couplers and other parts of matrix, and all of these effects are analyzed and considered to achieve the optimum performance in this paper. The matrix is designed on a substrate Rogers RT5880 with ε r = 2.2, substrate height = 0.787 mm, and loss tangent = 0.0009. Also the thickness of the copper cladding layer is 17 µm. The maximum amplitude and phase errors in outputs are 0.6 dB and 7 • , respectively, and VSWRs are less than 1.35 in the matrix bandwidth with at least 20 dB isolation between all ports.
