“…To realize the gigabit data rate while overcoming the high loss in high frequency bands, several promising techniques, including high-gain array antennas and multibeam antennas (MBAs), are likely to be adopted in the 5G communication systems [2]- [4]. Recently, array antennas with broad bandwidths and high gains were investigated based on planar waveguides [5]- [6], substrate integrated waveguides (SIWs) [7]- [8], and microstrip techniques [9]- [11]. In [12]- [14], a variety of MBAs were achieved based on reflectarrays [12], transmission lenses [13], and beamforming circuits [14].…”

In this paper, a compact, broadband, planar array antenna with omnidirectional radiation in horizontal plane is proposed for the 26 GHz fifth-generation (5G) broadcast applications. The antenna element is composed of two dipoles and a substrate integrated cavity (SIC) as the power splitter. The two dipoles are placed side-by-side at both sides of the SIC and they are compensated with each other to form an omni-directional pattern in horizontal plane. By properly combing the resonant frequencies of the dipoles and the SIC, a wide impedance bandwidth from 24 to 29.5 GHz is achieved. To realize a large array while reducing the complexity, loss and size of the feeding network, a novel dual-port structure combined with radiation and power splitting functions is proposed for the 1 st time. The amplitude and phase on each element of the array can be tuned, and therefore, the grating lobes level can be significantly reduced. Based on the dual-port structure, an 8-element array with an enhanced gain of over 12 dBi is designed and prototyped. The proposed antenna also features low profile, low weight and low cost, which is desirable for 5G commercial applications. Measured results agree well with the simulations, showing that the proposed high-gain array antenna has a broad bandwidth, omni-directional pattern in horizontal plane, and low side-lobes.

“…Butler matrices have been employed in various smart antenna systems [14]- [17]. Most recently, there has been an increasing interest in Butler matrices, and various fabrication technologies such as low-temperature co-fired ceramic (LTCC) [18], waveguide [19] and substrate integrated waveguide (SIW) [20]- [22], have been used to implement Butler matrices to millimeter-waves systems for 5G mobile or fixed wireless access communication. Various techniques for circuit miniaturization [23]- [24], bandwidth enhancement [25], and beams control [26] have been applied to traditional 4 × 4 Butler matrices, to obtain more attractive features.…”

“…About 25 o beam steering is achieved in a bandwidth of [22 -32] GHz with a gain of approximately 19 dBi. In [7], a multi-beam antenna composed of four single-polarized 1 x 4 multilayer SIW slot antenna arrays is designed. The antenna array can produce sixteen predefined sector beams with a gain of 14.5 dBi at 28 GHz.…”

A high-performance dual-polarized eight-element air-filled substrate-integrated-waveguide (AFSIW) cavity-backed patch antenna array is presented. The antenna operates in the [26.5-29.5] GHz band and provides a stable high data-rate wireless communication link between end-user terminals and access points in next-generation cellular systems. Its topology is carefully selected to maximize the performance of the array. In addition, by combining the AFSIW technology with a new antenna architecture, a low-profile, low-cost, stable, and high-performance array design is guaranteed. A prototype was fabricated and validated, demonstrating a wide active impedance bandwidth over ±35 o scanning range and low-cross polarization level within the entire frequency band. Index Terms-Air-filled substrate-integrated-waveguide (AF-SIW), aperture-coupled antenna, cavity-backed patch antenna, dual-polarized, 5G wireless communication, phased antenna array.
