Abstract
Methods of arranging and designing antennas to optimize electromagnetic field distributions in the near-field region of an antenna to optimize parameters such as electric field (E-field), magnetic field (H-field), specific absorption rate (SAR), power density (PD), etc. while ensuring specific performance of the antenna in the far-field region in terms of gain, efficiency, radiation pattern, etc.
Claims20
A method for arranging an antenna of a radio communication device, the method comprising:
- determining radiation characteristics for a far-field region of the antenna;
- controlling electromagnetic field distributions at a region in a near-field region of the antenna to optimize RF radiation at the region;
- determining an antenna configuration based on the control of the electromagnetic field distributions at the region;
- arranging the antenna based on the determined antenna configuration.

A radio communication device comprising:
- an RF transmitter configured to provide radio frequency (RF) signals;
- an antenna coupled to the RF transmitter, wherein the antenna is configured to:
- transmit provided RF signals at a propagation direction relative to a radiating element of the antenna;
- induce an electric field comprising a normal component that is perpendicular to a predetermined orientation relative to the propagation direction at a distance and a tangential component that is parallel to the predetermined orientation at the distance, wherein the magnitude of the tangential component is optimized based on the predetermined orientation.
