Circularly‐polarised origami‐inspired folding patch antenna sub‐array

Abstract

This work discusses the design of a microstrip patch antenna and its use as an orientation‐agnostic radiator in an origami‐inspired folding antenna array. The antenna is based on a perturbed circular patch design that is impedance matched to reside in a radial feed network for a 2 × 2 array. This 2 × 2 array can be switched to provide sum and difference pattern behaviour. Both the feed network and the ground plane are modified to enable folding of the structure according to the Miura‐ori pattern. The performance of a circularly polarised array is evaluated for a comprehensive range of fold angles to evaluate the impact of physical reconfiguration. Results for a simulated and fabricated circularly polarised array are provided for a 3 GHz design.

Design Optimization of Origami-Tunable Frequency Selective Surfaces

“…Electromagnetic Variables O RIGAMI, the art of paper folding, offers a large variety of engineering applications such as satellite or antenna deployment [1]- [4], self-folding micro-devices and robots [5], [6], tunable stiffness structures [7], acoustic energy focusing [8]- [11] and frequency tuning and reconfiguration in electromagnetic devices [12]- [18]. Integrating this intricate art form in engineering design provides the advantage of transforming a 2D manufacturing process into a 3D functional space with many degrees of freedom.…”

“…Integrating origami design in EM devices has significant practical implications in frequency tuning [13], [17], [26]- [29] and antenna reconfiguration and deployment [3], [4], [12], [18], [30]- [32]. The merit of a systematic origami design method is emphasized in such areas because it provides an efficient exploration method for previously overlooked design spaces.…”

Multiband circularly polarised CubeSat antenna operating in S, C, X, Ku, K, and Ka bands

“…An essential advantage of patch antennas is their low‐profile structure with less volume, small size, and easy Integration with devices; these advantages make the patch antennas work in wireless communications [14], satellite communication [13], microwave applications [14, 15], mobile phones, pagers [16], communication antennas on missiles [17], and in tracking vehicles and marines in the Global Positioning System (GPS) [18]. Several research challenges focus on providing communication solutions using CubeSats [19].…”

“…CubeSat satellite antenna design has many technical challenges in size, gain, bandwidth, polarisation, and impedance matching. The concern in this research work focuses on the research application space that does not need high-gain antennas, which contradicts the multiband techniques.An essential advantage of patch antennas is their lowprofile structure with less volume, small size, and easy Integration with devices; these advantages make the patch antennas work in wireless communications [14], satellite communication [13], microwave applications [14,15], mobile phones, pagers [16], communication antennas on missiles [17], and in tracking vehicles and marines in the Global Positioning System (GPS) [18].

Dual-wide Band bended cloth Antenna for ISM and WLAN applications

“…[6] One of the main advantages of small-sized antenna is its compatibility with the human body curves, as it is bended. [7] In this study, a 2 x 2 array was used to enhance the performance of patch antenna, and the behaviour of a circularly polarised array at an inclusive range of fold angles and impact of physical reconfiguration were evaluated. [8] The proposed antenna increased the impedance bandwidth from 2.9% (of a standard flat microstrip patch) to 9.0% [9].…”
