简介
We propose a reconfigurable design of a metamaterial‐inspired microstrip patch antenna, capable of tuning the frequency spectrum and beam radiation. The metamaterial component is composed of a three‐ring square split ring resonator (SRR) loaded in the antenna's substrate. Radiofrequency (RF) micro‐electro‐mechanical‐system (MEMS) switches are added in the gap of the proposed SRR to achieve frequency and radiation tuning in the performance of the microstrip patch antenna. The proposed reconfigurable antenna can be tuned to different frequencies depending on the operation states (no switching, one switch on, two switches on, and three switches on) of the SRR RF MEMS switches. The beam radiation can also be changed by setting in the ‘on’ state the SRR switches. Beam width and beam angle can be independently tuned depending on the four different switching states. The proposed pattern …
