A 1 × 2 triple‐band printed antenna array for use in next generation flying AD‐HOC networks (FANETs)

Abstract

A triple‐band 1 x 2 microstrip patch antenna array is proposed for use in next generation flying ad‐hoc network (FANET) communication in multi‐UAV systems. The antenna array resonates in the 3.6 GHz, 5.2 GHz and 6.7 GHz frequency bands, respectively. The antenna was designed and simulated using Agilent ADS Momentum using FR4 epoxy glass substrate (εr = 4.2 and h = 1.66mm). A hybrid feed technique is used for antenna arrays with quarter‐wave transformer based network to match the impedance from the feed‐point to the antenna to 50Ω. The antenna is optimized to resonate at triple‐bands by introducing two symmetrical slits at the non‐radiating edges of the patch. The bandwidths achieved for the three bands are 130 MHz, 125 MHz and 180 MHz, respectively, which are very practical. The antenna array design is less complex and can be used for the advanced antenna beam‐steering systems in next generation FANETs. © 2015 Wiley Periodicals, Inc.

FANET optimization: a destination path flow model

“…Thus, leading to a large amount of routing overhead that causes information loss. [25][26][27][28][29][30] are some of the authors that concentrated on improving the communication models in FANET. Muhammad et al, [25] and Antinio et al, [26] developed a hybrid communication scheme for the efficient and low-cost deployment of future FANET and a new domain for communications in FANET respectively.…”

“…The communication strength between two nodes is dependent on the distance between them. Following other academic [29] and industrial [30] papers, normalized transmission rates and ranges are adopted in this work. With application to sports coverage, we adopted a football field scenario of 160 feet (48.5m) wide and 360 feet (109.1m) long.…”

Wideband and high gain antenna arrays for UAV‐to‐UAV and UAV‐to‐ground communication in flying ad‐hoc networks (FANETs)

“…It is also suggested that longer transmission ranges can be achieved with the help of directional antenna as compare to omni‐directional antenna and spatial rescue of network significantly increases with the help of directional MAC protocols . In the past, researchers have proposed multiple antenna designs and also suggested their implementation techniques for different type of UAVs. Current small UAVs are prototyped with commercial‐of‐the‐shelf (COTS) equipment which may consists of Zigbee radio modules along with the monopole antenna for communication purposes .…”

Circularly Polarized 2×2 Mimo Antenna for Wlan Applications

“…In a design, a dual-excitation approach with dumbbell-shaped defected ground structure (DGS) was used for reconfigurability in beam steering, and improvement in front to back-lobe ratio (FBR) [4,5]. To avoid the problem of narrow bandwidth a coplanar waveguide (CPW) was used for designing CP polarized rhombic antennas for radio receivers [6].…”
