The mechanical foldability is achieved using a surrogate hinge architecture, allowing the antenna to fold nearly 360 • without mechanical or electromagnetic (EM) failure, thus enabling beam reconfigurability. Using a multipermittivity DR based on low-cost polylactic acid (PLA) materials with ϵr1 = 2.72 (100% infill) and ϵr2 = 1.24 (18% infill), the TE11, TE21, and hybrid mode B are excited, and thus wideband impedance bandwidth is achieved. The proposed compact MIMO antenna achieves high isolation of 40 dB, with a gain of 7.5 dBi at 13.5 GHz and a radiation efficiency of 85%. Experimental validation confirms that the measured results align well with the simulated results over the operating frequency band.
