WIDEBAND DUAL-POLARIZED PATCH ANTENNA ARRAY AND METHODS USEFUL IN CONJUNCTION THEREWITH

摘要

A flat antenna element including at least one radiating patch; and at least one impedance transformer including a feed-point arm connected to the patch which intersects between micro-strip feed lines and the radiating patch, wherein said arm has a first end electrically connected to an individual feed line and a second end which is electrically connected to the patch, and wherein said second end electrically connected to the patch has a width small enough to yield a level of impedance, for the arm, which is more than, e.g. more than twice, the level of impedance of the patch, and wherein the width of the feed line of end connected to patch is narrower than the end connected to the feed line.

1. A flat antenna element including:
at least one radiating patch; andat least one impedance transformer including a feed-point arm connected to the patch which intersects between micro-strip feed lines and the radiating patch,
wherein said arm has a first end electrically connected to an individual feed line and a second end which is electrically connected to the patch, and wherein said second end electrically connected to the patch has a width small enough to yield a level of impedance, for the arm, which is more than, e.g. more than twice, the level of impedance of the patch, and wherein the width of the feed line of the end connected to the patch is narrower than the end connected to the feed line.
