“…On the other hand, the work reported in [13] has proposed a hybrid dual-antenna formed by an inverted-F antenna and an open-slot antenna that only focus on 3.6-GHz band (3.4-3.8 GHz) operation [13]. To satisfy future 5G applications, MIMO antennas for 5G applications have been discussed in [14,15]. For smartphone applications, the recent works reported in [16], [17] and [18] have proposed 8-element 10- [19,20].…”

A hybrid antenna is proposed for future 4G/5G MIMO (multiple input multiple output) applications. The proposed antenna is composed of two antenna modules, namely, 4G antenna module and 5G antenna module. The 4G antenna module is a two-antenna array capable of covering the GSM850/900/1800/1900, UMTS2100, and LTE2300/2500 operating bands, while the 5G antenna module is an 8-antenna array operating in the 3.5 GHz band capable of covering the C band (3400-3600 MHz), which could meet the demand of future 5G application. Compared with ideal uncorrelated antennas in an 8 × 8 MIMO system, the 5G antenna module has shown good ergodic channel capacity of approximately 40 bps/Hz, which is only 6 bps/Hz lower than ideal case. This multi-mode hybrid antenna is fabricated, and typically experimental results such as S-parameter, antenna efficiency, radiation pattern, and envelope correlation coefficient (ECC) are presented.

“…For example, a dual polarization 2 × 4 antenna structure [22] has been proposed with 12 dBi peak gain and the operating band from 5150 to 5850 MHz, and in [23], a 5 GHz band patch antenna is loaded with the Complementary Split Ring Resonators (CSRR) for miniaturization, lower gain of −0.16 dBi and limited 80 MHz operating bandwidth (BW). Similarly, in [24], the 8 elements MIMO antenna with 6.5 dBi gain serving narrow frequency bandwidth from 4.985 to 5.15 GHz has been proposed. Furthermore, in [25], an antenna array with 3 monopole patches, inverted L and inverted Z with slightly wider bandwidth covering 5 to 6 GHz with a gain from 2 to 3.7 dBi is proposed.…”

In this work, a novel antenna structure has been proposed, which consists of multiple sub-array features i.e., a field selectable beam (90°, 180°, 270°, and 360°) and the choice of gain (11.16, 14.59 and 17.25 dBi) that can be easily adapted to cater for the dynamic scenarios in the transportation environment. The sub-arrays were designed using the microstrip patch antenna (MPA) concept with capacitive feed and dual substrate stacked up configuration for superior operating bandwidth covering the entire 802.11ac (5.17 to 5.85 GHz Industrial Scientific and Medical (ISM) band), in addition to the extended coverage for 4.92 to 4.98 GHz licensed band with narrow azimuth beamwidth of 24°. The sub-array was designed, simulated and experimentally evaluated and the beamforming results revealed that the antenna structure can be integrated with beamforming concepts to provide an enhanced wireless link between the ground base station and the mobile terminals that allows beam steering to focus on the targeted direction and null the interference directions with small beam width. It is expected that the proposed configurable gain/beam beamforming antenna array will further reduce the deployment cost and enhance the anti-interference performance by twofold , and shall bring the user experience in the transportation market to the next level.

“…La explosión de los datos móviles ha conllevado la búsqueda de mayores velocidades para satisfacer las demandas de servicios como videollamadas, video móvil de alta definición y sincronización de fotos y videos de móviles; de igual forma la proliferación de dispositivos como tablets, smartphones y gadgets, hace que se requiera una mayor capacidad en las redes, sean estas fijas, como WiFi 802.11n/ac (Nassir, Mustaqim, & Khawaja, 2014), o móviles como HSPA+ o LTE; inclusive se ha necesitado de desbordamientos de la red móvil en redes WiFi con estrategias como la conocida WiFi Offload (Sraga, Momcilovic, & Tekovic, 2014). Lo anterior se traduce en un crecimiento exponencial del tráfico que puede apreciarse en reportes como el del pronóstico global de datos móviles (Cisco, 2015) donde se muestra cómo el video móvil superó el 50% del total del tráfico de datos por primera vez en 2012 y cómo este mismo llegó al 55% para finales de 2014.…”
