To support the ever-increasing demand on connectivity and datarates, multiple beam antennas are identified as a critical technology for the fifth generation (5G), the sixth generation (6G) and more generally beyond 5G (B5G) wireless communication links in both terrestrial networks (TNs) and non-terrestrial networks (NTNs). To reduce the cost and power consumption, there is a marked industrial interest in adopting analogue multiple beam antenna array technology. A key sub-system in many of such antenna arrays is the circuit type multiple beamforming network (BFN). This has led to a significantly renewed interest in and new technological developments of Butler matrices, Blass matrices, and Nolen matrices as well as hybrid structures, mostly at millimeter-wave frequencies. To the best of the authors' knowledge, no comprehensive analysis and comparison of circuit type multiple BFNs have been properly reported with focus on 5 G and 6 G applications to date. In this paper, the principle of operation, design, and implementation of different circuit type multiple BFNs are discussed and compared. The suitability of these sub-systems for 5 G and B5G antenna arrays is reviewed. Major technology and research challenges are highlighted. It is expected that this review paper will facilitate further innovation and developments in this important field.INDEX TERMS Fifth generation (5G), sixth generation (6G), beyond 5G (B5G), multiple beam antenna arrays, circuit type beamforming networks (BFNs), Blass matrix, Butler matrix, Nolen matrix, terrestrial network (TN), non-terrestrial network (NTN).This article has been accepted for inclusion in a future issue of this journal.

“…There are several beam‐forming networks (BFNs) which can build multi‐beam arrays, including Butler matrixes, 1 Luneburg lens, 2,3 parabolic reflectors, 4,5 and so on. Butler matrix is an effective method to realize multi‐beam or beam switching with the characteristics of low‐profile, but the complex hybrid BFNs will bring greater insertion loss in millimeter frequency band 6 . Conventional lens antennas and reflector antennas have much lower loss compared to Butler matrixes.…”

In this article, a multi‐beam substrate integrated waveguide (SIW) leaky‐wave antenna (LWA) is proposed for millimeter‐wave radar applications, which owns the advantages of 2‐D scanning capability, high gain, low profile, and single layer configuration. The proposed antenna consists of a beam‐forming network (BFN) based on a 2‐D SIW parabolic reflector with eight waveguide feedings, and a 16‐element LWA array. The open‐stopband of the LWA is suppressed by employing a longitudinal slot into a conventional transverse slot LWA unit. In the E‐plane, the BFN can generate eight desired distributions of the amplitude and the phase gradients which steers beam from −17.3° to 30.8° with the crossover level higher than −5.22 dB. In the H‐plane, the frequency scanning LWA array can offer a continuous beam scanning range from −23° to 19° with operating frequency from 21 to 29 GHz. Finally, the antenna is prototyped and experimentally verified. The measured results are in accord with the simulated ones. The characteristics of the proposed antenna make it a very promising solution for applications in low‐cost millimeter‐wave radar systems.

“…Hence, the design of compact sub-6G filters is a hot research topic for mobile portable devices. Substrate integrated waveguide (SIW) is widely used in RF passive device designs due to low loss, low cost, and flexibility of integration properties, such as filter [1][2][3][4][5][6], antenna [7][8][9][10][11], phase shifter [12][13][14][15][16], power divider [17][18][19][20][21], and coupler [22][23][24][25][26]. However, SIW filters under 6 GHz is still outsize to meet the requirement of portable communication devices because of the long wavelength.…”

A compact substrate integrated waveguide (SIW) filter based on composite right/lefthanded (CRLH) resonator units is implemented in this paper. The filter is composed of two CRLH resonator units serially connected by a SIW transmission line unit. The structure of the filter and equivalent circuit transmission behavior are analyzed, and a novel design method by optimizing the length and width of the interdigital metal slots to decrease the filter operation frequency is proposed. To further demonstrate the design theory and performance of the proposed filter, the filter was designed and fabricated on an RT6010 dielectric material. The measurement results show that the proposed filter works at a center frequency of 5.8 GHz with 200 MHz bandwidth The insertion loss is 2.3 dB, and the filter size is only 10 mm × 7.4 mm.
