“…Los diseños de antenas de microcinta con base en ranuras (slots) permiten tener varias bandas de operación, y cubren múltiples aplicaciones de comunicación inalámbrica como WiFi, GPS, radar, WiMax, WLAN, comunicación punto a punto, entre otras. En los últimos años este tipo de estructuras ha recibido especial atención por su aplicación en tecnologías de la última década como el WiGig y 5G [11][12][13]. La demanda actual referente a sistemas de comunicación inalámbrica es alta, y es necesario o se hace más cómodo que los sistemas tiendan a disminuir en tamaño y aumentar en eficiencia y rendimiento, varios modelos han sido propuestos con el objetivo de lograr esta reducción de tamaño [14][15][16].…”

Un nuevo sistema de antenas de microcinta es presentado en este trabajo, en el cual se insertan ranuras rectangulares cuyas dimensiones y separación están determinadas por diferentes órdenes de la secuencia de Cantor. Las pérdidas por retorno fueron analizadas para determinar el efecto de este tipo de secuencia de ranuras en el parche, mostrando la generación de dos bandas en el rango de 1 a 6 GHz. La antena de microcinta fue diseñada aplicando un número de ranuras en el parche cuyos tamaños se basan en la secuencia Cantor hasta la cuarta iteración. El arreglo presentado permite tener dos frecuencias de resonancia en el rango de 1 a 6 GHz, los resultados computacionales y experimentales presentan una gran concordancia. La simulación de los modelos se realizó utilizando el software HFSS, utilizando un sustrato FR4 con e r = 4,4 y un espesor de 1,58 mm. Las antenas presentadas en este artículo a diferencia de una antena de microcinta convencional con las mismas dimensiones, presenta dos bandas de frecuencia las cuales poseen ligeras diferencias entre cada iteración. Los nuevos sistemas de antenas tipo parche presentados en este trabajo permitieron obtener la generación de doble banda después de añadir ranuras con base en la secuencia de Cantor.

“…The system can provide a transmission rate of multi-gigabit [11]. Previous works [12]- [14] have demonstrated several possible antenna designs for WigGi applications and several 60 GHz radios are also available [15], [16]. However, little work has been done to demonstrate a single antenna for the new possible tri-band enabled devices covering 2.4, 5, 60 GHz after the merging of WiFi and WiGig.…”

This paper presents a low-cost printed-circuit-board (PCB) based dual-band antenna for future wireless local area network (WLAN) applications. The antenna is designed to fully cover both WiFi channels (2.4/5.2/5.8 GHz) and Wireless Gigabit Alliance (WiGig) channels (57-64 GHz). At the WiFi frequency bands, the antenna is based on a printed monopole, while at the WiGig frequency band, a wideband higher-order mode patch antenna is adopted. A compact microstrip resonance cell (CMRC) low-pass filter is also designed to allow feeding the monopole antenna at WiFi frequency bands while isolating the monopole from the patch for WiGig operation. The design is fabricated by standard PCB and plated-through-hole technologies and its performance is validated by measurement.Index Terms-WLAN, WiFi, WiGig, 802.11, wideband, printed monopole, higher-order mode patch antenna, 60 GHz.I.

“…Although, SU-8 does not have good material properties (very high RF losses) for RF/antenna applications, it can be easily processed to form air cavities within, thereby taking advantage of good material properties of air. A microfabricated SU-8-based patch antenna structure exploiting air cavities was recently reported to achieve 57-66 GHz bandwidth and a maximum realized gain of 7dBi [2]. Also microfabrication techniques in creating closely spaced holes underneath a patch antenna on high dielectric substrate were used to synthesize a low dielectric environment [3].…”

“…To this end, two-layer antenna structure using the combination of RF-compatible quartz substrate and low-cost pyrex substrate is adopted. The design strategy is to combine the advantages of multiple approaches of previous works [2]- [5]. The design makes use of CPW loop feeding mechanism on quartz substrate to provide broad BW.…”

“…It uses low cost pyrex material where air cavities are easily formed by a single process step, which does not only reduce cost but also take advantage of good RF properties of air. It is worth noting that this approach is much simpler and lower cost in terms of microfabrication as compared to forming air cavities in SU-8, which requires multiple process steps [2].…”

The design, fabrication and characterization of a 2x8 patch antenna array operating in the IEEE 802.11ad frequency band (57-66 GHz) is presented. The design is based on two-layer structures, where the radiating patches placed on top substrate are fed by conductor backed coplanar waveguide (CPW)-fed loop slots, which are placed on the bottom substrate. The top layer is formed by using a low-cost pyrex (εr = 4.9, tanδ = 0.01) substrate of 500µm thickness. The pyrex is then etched away to a thickness of 100µm, where 400µm of air volume is formed underneath. This approach does not only benefit from the lowcost feature of pyrex but also exploits the low-loss nature of air. The thin layer of pyrex is solely used for mechanical support for the radiating patches while the air provides good RFenvironment for the array. The bottom substrate housing the CPW feed network is an RF-compatible and microfabrication friendly quartz (εr = 3.9, tanδ = 0.0002) of 525µm thickness. The simulations indicate a good maximum realized gain of 19.3 dBi of which variation over ∼ 17% bandwidth is relatively constant changing from 17-19.3 dBi.
