Reconfigurable Slotted Antenna Inspired by Multidimensional Modulation

Multidimensional modulation was widely studied in the past decades due to the explosive development of modern wireless communication. Here, we propose a spirally reconfigurable slotted antenna inspired by the multidimensional modulation. The amplitude, phase, and frequency-shift modulation are analog by integrating three-dimensional mechanical switching to a spiral slotted antenna. The maximum gain of the reconfigurable antenna can be adjusted in the type of 2 encoding bits at 9.5 GHz. Our work may pave the way to a high-performance reconfigurable antenna for 6G communication.
