A triple-band antenna array for next-generation wireless and satellite-based applications

Abstract

In this paper, a triple-band 1 × 2 and 1 × 4 microstrip patch antenna array for next-generation wireless and satellite-based applications are presented. The targeted frequency bands are 3.6, 5.2 and 6.7 GHz, respectively. Simple design procedures and optimization techniques are discussed to achieve better antenna performance. The antenna is designed and simulated using Agilent ADS Momentum using FR4 substrate (r = 4.2 and h = 1.66 mm). The main patch of the antenna is designed for 3.6 GHz operation. 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 50. The antenna is optimized to resonate at triple-bands by using two symmetrical slits. The single-element triple-band antenna is fabricated and characterized, and a comparison between the simulated and measured antenna is presented. The achieved simulated impedance bandwidths/gains for the 1 × 2 array are 1.67%/7.75, 1.06%/7.7, and 1.65%/9.4 dBi and for 1 × 4 array are 1.67%/10.2, 1.45%/8.2, and 1.05%/10 dBi for 3.6, 5.2, and 6.7 GHz bands, respectively, which are very practical. These antenna arrays can also be used for advanced antenna beam-steering systems. Copyright © Cambridge University Press and the European Microwave Association 2014

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

“…This article extends the single‐element antenna design, optimization and characterization study performed previously in and presents the characterization results of a fabricated triple‐band 1 × 2 printed antenna array for use in multi‐UAVs communication in next generation FANETs. The 1 × 2 antenna array was designed in , but no fabrication was performed at that point.…”

This article also reports the UAVs antenna research performed in the last decade and gives a detailed summary of the previous antenna designs proposed in the literature and compare it with the work presented in this paper in terms of antenna type, operating frequency bands, substrates, design complexity and applications.…”

“…The proposed 1 × 2 triple‐band MPA array elements have similar dimensions like the previously designed single‐element MPA, its in‐depth mathematical design procedure is briefly discussed in . The 1 × 2 antenna array design process started with rectangular patch antenna operating at 3.6 GHz.…”

“…The commonly available flame resistant (FR4) epoxy‐glass substrate has been used having dielectric constant ( ε r ) of 4.2 and thickness ( h ) of 1.66 mm. The resonating patch‐antenna width, length, and microstrip transmission‐line (tx‐line) width for the characteristic impedance of 50Ω is determined . In order to achieve the triple‐band behavior, surface current distribution on the resonating patch may be altered.…”

“…In order to achieve the triple‐band behavior, surface current distribution on the resonating patch may be altered. This is accomplished by introducing the two symmetrical slits at the non‐radiating edges of the patch , as shown in Figure .…”
