Embodiment Construction

[0016] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of currently known or available techniques. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but may be limited within the scope of the appended claims and their equivalents. Modify within the complete scope of the object.

[0017] Disclosed herein is a reconfigurable multi-band antenna that can be dynamically changed based on sensor input to reduce SAR measurements. The antenna may include a near end, a far end and an intermediate point. The antenna may also include a first feed line located between the proximal end and the intermediate point and a second feed line located between the distal end and the intermedi...

Abstract

A mobile node (MN) comprising an antenna comprising a proximate end, a distal end, and a midpoint, a first feed coupled to the antenna between the proximate end and the midpoint, a second feed coupled to the antenna between the distal end and the midpoint, a first switch configured to toggle between coupling the first feed to a main feed and coupling the second feed to the main feed, and a controller configured to control the toggling of the first switch.

Description

[0001] Related Applications Cross Application [0002] This application claims the benefit of prior application to U.S. Nonprovisional Application No. 13 / 720017, filed December 19, 2012, entitled "Reconfigurable Multiband Antenna", which The content of is incorporated herein by reference in its entirety. Background technique [0003] A mobile node (MN) can wirelessly transmit signals to corresponding components through antennas. Wireless signals may be transmitted in the form of radiated energy, such as radio frequency (RF) energy. Radiant energy emitted by the MN may be absorbed by the user's body. The amount of radiation absorbed by the user's body while operating the MN is defined as the MN's / antenna RF energy absorption ratio (SAR). High levels of SAR are considered unsafe. MNs including antennas with SAR above a certain threshold are not available for sale to the public. Contents of the invention [0004] In one embodiment, the invention includes an apparatus compr...
