Embodiment Construction

[0123] image 3 An embodiment of the device according to the invention is shown. Device 15 includes an uppermost metal layer 17 extending across the bridge structure formed by polymer layer 19 . The polymer layer includes polymonochloroparaxylylene (parylene-C).

[0124] The space below the polymer layer 19 accommodates the coplanar waveguide 23 and the second plate 75 on the substrate 21 . The total support distance L is provided by the distance W and the distance G of the width of the coplanar waveguide, where the two distances G are equal and provide the remaining distance between the edge of the coplanar waveguide and the vertical portion of the polymer 19 .

[0125] Parylene is commonly used as a waterproof material in MEMS fabrication. It is a plastic like a polymer with a very low spring constant (ie high elasticity). Dichloro-p-xylylene dimer is used in this embodiment of the invention because it contains suitable softness, dielectric strength, and other properties...

Abstract

A micro electromechanical (MEMS) antenna (36) is positioned on one side of a substrate and is connected to a MEMS switch comprising a capacitor bridge (46) and to a transmission line (42) by means of a thru hole or via (48) which forms an electrically conducting path through the substrate. This arrangement provides a common ground plane for the antenna and switch and shields the switch from the electromagnetic radiation received or transmitted from the antenna. The switch may comprise a topmost metal layer which extends across a bridge structure formed by a polymer layer. The polymer layer comprises poly-monochloro-para-xylene (parylene-C). Homogeneous or heterogeneous antenna array structures are implemented. The antenna arrays may include one or more different type of antennas with for example different shapes, rotations and reflections.

Description

[0001] This application is a divisional application of an invention patent application titled "Improvements to Reconfigurable Antennas and Improvements Related thereto" filed on June 13, 2008 with a priority date of June 13, 2007 and application number 200880019799.1 . technical field [0002] The present invention relates to reconfigurable antennas for use in wireless communications incorporating microelectromechanical (MEMS) components including novel switches. Background technique [0003] Wireless communication systems that can dynamically adapt to changing propagation characteristics of the environment will be the key to next-generation communication applications. [0004] An antenna is an extremely important component in any wireless device because it transmits and receives radio waves. Antennas are used as matching devices from transmission lines to free space and vice versa. An ideal antenna radiates all energy entering from a transmission line feeding the antenna ...
