“…The ability to change the antenna shape on the fly provides the capability to either remotely deploy an antenna 45,46 or reconfigure its functionality [47][48][49] . Here, we demonstrate two morphing radio-frequency (RF) antennas that can rapidly, reversibly transform between on-demand shapes.…”

Shape-programmable soft materials that exhibit integrated multifunctional shape manipulations, including reprogrammable, untethered, fast, and reversible shape transformation and locking, are highly desirable for a plethora of applications, including soft robotics, morphing structures, and biomedical devices.Despite recent progress, it remains challenging to achieve multiple shape manipulations in one material system. Here, we report a novel magnetic shape memory polymer composite to achieve this. The composite consists of two types of magnetic particles in an amorphous shape memory polymer matrix. The matrix softens via magnetic inductive heating of low-coercivity particles, and highremanence particles with reprogrammable magnetization profiles drive the rapid and reversible shape change under actuation magnetic fields. Once cooled, the actuated shape can be locked. Additionally, varying the particle loadings for heating enables sequential actuation. The integrated multifunctional shape manipulations are further exploited for applications including soft magnetic grippers with large grabbing force, sequential logic for computing, and reconfigurable antennas.

“…To cater for the limited space on CubeSats, most developers have tried to maintain the use of a single antenna to maintain simplicity and avoid the use of deployment mechanism [1,34,68]. However, several other researchers implemented simple monopole antennas which are deployable using a tape-spring method [70]. The antenna operates at 250 MHz using a length of 55.88 cm and a ground plane sized at 114.3 × 152.4 cm 2 [70].…”

Cube Satellite (CubeSat) technology is an attractive emerging alternative to conventional satellites in radio astronomy, earth observation, weather forecasting, space research, and communications. Its size, however, poses a more challenging restriction on the circuitry and components as they are expected to be closely spaced and very power efficient. One of the main components that will require careful design for CubeSats is their antennas, as they are needed to be lightweight, small in size, and compact or deployable for larger antennas. This paper presents a review of antennas suitable for picosatellite applications. An overview of the applications of picosatellites will first be explained, prior to a discussion on their antenna requirements. Material and antenna topologies which have been used will be subsequently discussed prior to the presentation of several deployable configurations. Finally, a perspective and future research work on CubeSat antennas will be discussed in the conclusion.

“…Mechanical reconfiguration mechanisms for deployable antennas are based on the nature of the antennas, their composite material, and their deployment mechanism. For example, the reconfiguration of deployable antennas that are designed with bistable composite tape springs can be achieved using one-way linear or rotary actuator (Murphey et al 2010;Jeon and Murphey 2011;Costantine et al 2012b). Antennas made with neutrally elastic mechanism (NEM) tape springs require two-way actuators to be reconfigured (Murphey et al 2010;Jeon and Murphey 2011;Costantine et al 2012b).…”
