Patent ID: 8766868

Claim:
A method of mitigating near electric fields generated by a wireless communication device, comprising: configuring at least a first resonant structure to resonate at or near at least a first operating frequency of an antenna of the wireless communication device, wherein the first resonant structure does not include a feed port; electromagnetically coupling the first resonant structure to the antenna to mitigate the near electric fields at the operating frequency; and coupling a transmitter to the antenna, the transmitter being configured to communicate electromagnetic signals to the antenna; and wherein configuring the first resonant structure to resonate at or near the first operating frequency of the antenna of the wireless communication device comprises: configuring the first resonant structure to comprise at least a first portion having an inductive impedance and at least a second portion having a capacitive impedance; and wherein configuring the first resonant structure to resonate at or near the first operating frequency of the antenna of the wireless communication device comprises: positioning the second portion of the first resonant structure proximate to a ground plane to establish the capacitive impedance between the second portion and the ground plane; and wherein configuring the first resonant structure to resonate at or near the operating frequency of the antenna of the wireless communication device further comprises: electrically coupling a first port of the first portion of the first resonant structure to the second portion of the first resonant structure; and electrically coupling a second port of the first portion of the first resonant structure to a ground potential; and wherein the first portion and the second portion are coplanar.
