Embodiment Construction

[0022] In general, embodiments provide antennas that operate across multiple frequency ranges. This may include applying metal components to the dielectric substrate to form the antenna, and slotting the metal components of the antenna to increase the electrical size and electrical characteristics of the antenna. The antenna can be used for communication in ultra-wideband wireless devices. Other aspects include shaping at least one edge of the metal part of the antenna to facilitate impedance parameters of the antenna, and / or shaping the ground part of the antenna to accommodate a ground plane having a similar shape to the antenna. Various processes are provided for optimizing antennas across multiple frequency spectrums.

[0023] In the following description, specific details are given to provide a thorough understanding of the embodiments. However, it will be understood by those of ordinary skill in the art that this embodiment may be practiced without these specific detai...

Abstract

A system, apparatus and method for a diverse spectrum antenna is disclosed. The diverse spectrum antenna may comprise a circuit board having a ground plane and a chip antenna including a notch, wherein the chip antenna is mounted on the circuit board at a selected distance from the ground plane.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This application for patent claims priority to Provisional Application No. 60 / 762,770, filed January 27, 2006, entitled "An Internal UltraWideband Antenna for Handsets and Other Devices," which is assigned to the assignee of this application , which is expressly incorporated herein by reference. technical field [0003] The subject technology relates generally to communication systems and methods, and more specifically, to systems and methods for improving device performance by employing internal chip antennas. Background technique [0004] Wireless handsets have become very small over the last decade while more services have been added, such as Global Positioning System (GPS) and Bluetooth technology. The new technologies involved include ultra-wideband (UWB) services for providing new communication systems. Typically, UWB systems employ very low power (eg, -41.3 dBm / MHz) for short ranges and use at least 500 MHz of b...
