Abstract:
Prototyping is highly important in validation of theoretical and simulation results. Micro-Electro-Mechanical Systems (MEMS) are widely used in biotechnology, medicine, communication and inertial sensing. Utilizing the integrated combination of electro and mechanical systems, MEMS are able to achieve new functionality. In particular, a folded dipole antenna array is an important component in radio frequency communication due to its broadband feature. One major drawback preventing folded dipole antenna arrays from being used in certain practical applications lies in their unidirectional nature, i.e., their radiation direction is fixed once the fabrication is done and not easy to change in use. In this paper, we propose a novel method to implement MEMS for a folded dipole antenna array, which makes the radiation direction flexible and thus omnidirectional. This prototype broadens the application of folded dipole antenna arrays. A comparison of whether MEMS are implemented on radiating elements to make them move or as circuit elements is also reported to provide insight for future research in the field of radio frequency MEMS.
