Abstract: This letter presents a compact circularly polarized (CP) microstrip patch antenna (MPA) array with inherent self-decoupling capability for the BeiDou-B3 (1.268 GHz ± 10 MHz) navigation band.
Liquid crystal elastomers have potential as 4D-printing actuators, but it is difficult to achieve complex shape changes in structures. Here, the authors report a 4D-printing strategy that combines vat ...
