“…The exponential flare has contoured holes or vias along the tapered edges of the metalized conductors. These contours control and limit the radiation losses introduced in the SCVA [9]. The exponential profile of the antenna is characterized by the opening rate R, which is governed by the well-defined relations developed in [28].…”

“…The patch array designed on PCB offered a gain of 13 dBi with a single resonance at 28 GHz while the LTCC material array (2 × 2) achieved a gain of 10 dBi with a wide bandwidth of 10.3% (26)(27)(28)(29). In [9], the authors utilized the substrate integrated waveguide (SIW) technology to design a low-cost and high-gain antenna array for 5G communication. Slotted antennas in the shape of rectangles are designed on a substrate with permittivity of 2.2.…”

We present a 4 × 4 slot-coupled Vivaldi antenna (SCVA) array unit cell, which offers wide bandwidth and high gain (~23 dBi) at the millimeter wave (mmW) frequencies of 28 GHz and 38 GHz. A single SCVA element is first presented, which has a bandwidth of 25-40 GHz with an average gain of~13 dBi at the frequencies of interest. This antenna element is then used to design a 1 × 4 linear SCVA array matched to a 50 Ω impedance via a modified Wilkinson power divider (WPD). Next, the 1 × 4 linear array is used to construct a 4 × 4 antenna array unit cell. The proposed 4 × 4 antenna array unit cell is fabricated, and the characteristics of its elements (i.e., the single SCVA, 1 × 4 linear array, and WPD) are thoroughly investigated. Further, the 4 × 4 array is tested for signal reception of various digital modulation formats at lab environment using high-speed digital signal oscilloscope. In particular, a 2.5 Gbps data rate is successfully transmitted achieving receiver sensitivity of −50 dBm at 2 × 10 −3 bit error rate (BER) for 32 quadrature amplitude modulation (QAM) with a system baud rate of 500 MHz. The wide bandwidth and high gain along with the excellent performance of the proposed 4 × 4 antenna array unit cell makes it an excellent candidate for future 5G wireless communication applications.

“…The conventional cavity‐backed antennas have good radiation performance such as low FTBR, gain enhancement, and low‐mutual coupling between antenna elements. The cavity behind the slot is used to achieve high‐gain unidirectional radiation . In order to improve the radiation performance and reduce the fabrication complexity, the substrate integrated waveguide (SIW) technique is a more competitive candidate for K‐ and Ku‐bands .…”

In this article, a novel substrate integrated waveguide (SIW) is used to design multifrequency cavity‐backed log‐periodic slot antenna. The proposed design has three layers of cavity‐backed structure namely feeding SIW, resonant SIW, and log‐periodic slot SIW in order to achieve low loss, high gain, and easy integration with high‐frequency components. The proposed structure also includes an inductive window slot to couple the energy from feeding SIW to resonant cavity. The experimental results shows that 10‐dB impedance bandwidth of 870 MHz (7.9%), 390 MHz (2.7%), 410 MHz (2.5%), 310 MHz (3.9%), and 420 MHz (2.2%) are obtained at resonant frequencies 11.25 GHz, 14.25 GHz, 15.95 GHz, 16.9 GHz, and 19.15 GHz, respectively. Also, a realized gain of around 18.24 dB is obtained at the bore sight direction. Moreover, the simulated and experimented results are in good agreement and make the antenna more suitable for Ku and K band applications.

“…Although a base station (BS) can be designed for a specific scenario, a mobile terminal (MT) needs to be adaptive for various propagation environments. In the open literature, arrays have been most popular approach to provide antenna gain for 5G configurations [10]- [12]. However, it is evident that arrays for MTs are strongly limited because of mechanical restrictions.…”

Abstract-Wideband fifth generation (5G) systems utilizing high carrier frequency and multiple-input multiple-output (MIMO) raise major challenges for the system design. Wave propagation and practical hardware tradeoffs at higher frequency ranges provide new boundary conditions for the implementation. This paper addresses system performance boundaries and the analysis method towards multibeam communications at mmW. We combine analysis from antennas and propagation to the RF transceiver specifications and beamforming requirements. Realistic propagation model and antenna implementation is used to generate beam-specific path gains and provide a wide variety of user scenarios. Using this approach, system level interdependencies and RF performance boundaries can be verified with different antenna configurations in various propagation environments. As an example, we present MIMO link budget analysis targeting 10 Gbits/s for multiple devices in the office scenario at 27 GHz.
