Small Size CPW-Fed Chip Antenna for Integration with RF/Wireless Communication Systems

Abstract: A small size dual-band antenna for integration with 5-6 GHz RF/Wireless communication systems is presented. The size and structure of the antenna are designed for integration with a RF printed circuit board of a given size (thickness=1.36mm=0.045λ), metallization structure (4-level of metalization) and material properties (FR4, εr=3.78, loss tangent=0.01). It is capacitively fed by a coplanar waveguide (CPW) to allow easier integration with active and passive circuit components. The procedure used to develop this new antenna structure is described. Computational results showing the antenna’s impedance behavior and radiation characteristics are given. I. Introduction: New communication environments typically consist of a broad range of application classes of devices providing data, video, and audio services. Interoperation of these devices without mutual interference is required. In addition the proliferation of cheaper, smaller, more compact and higher performance mobile terminals has been fueling the effort to establish unified multi-service wireless local area network
