摘要：

The functionality of the patch antenna with switchable slot (PASS) is realized by integrating a commercially packaged MEMS (microelectromechanical system) switch and a novel bias network. The proposed antenna includes the fully integrated dc bias network capable of actuating the MEMS switch on the slot. The bias network can minimize the interference between dc bias and RF radiation mechanism with a negligible loss. By using aMEMS switch and the bias network, the patch antenna operates at 4.57 GHz and 4.88 GHz. The fabricated design shows acceptable return losses and directivities at the broadside direction when the switch is on and off. The influence of RF MEMS switch on the antenna impedance and radiation pattern is addressed.
