Parallel Solenoid Feeds for Magnetic Antennas

摘要

The present disclosure provides systems and methods for enhancing the performance of permeable antennas. Further, the parallel solenoid feed system disclosed herein may be used to reduce or eliminate significant phase delays in antennas, which may lead to destructive interference. Moreover, use of the parallel solenoid feed in an antenna eliminates the need for multiple feeds, complicated feed networks, and elaborate matching circuits. Using the parallel solenoid feed in circular magnetic antennas may enhance the performance of the antenna through maintaining the flux. Finally, many adjustable parameters for further tuning and/or optimizing the performance of particular antenna design have been identified herein, which may allow those skilled in the art to utilize known systems, such as full wave simulation software, to determine the desired final design for an antenna utilizing a parallel solenoid feed.

1. A feed for a magnetic antenna with a ground plane, the magnetic antenna having a width, a height perpendicular to the ground plane, and a length longer than the width and the height, the feed comprising:
a first conductor and a second conductor bisecting the width of the magnetic antenna; a first set of shorting pins electrically connecting the first conductor and the ground plane at generally regular intervals along the length of the antenna; and a second set of shorting pins electrically connecting the second conductor and the ground plane at generally regular intervals along the length of the antenna.
