The reading range of a tag antenna usually decreases markedly as the antenna size decreases, because of the antenna's reduced gain. This letter describes the use of circular polarization to reduce the size of a tag antenna without decreasing its reading range. This approach resulted in a 33 x 33-mm antenna with a substrate thickness of 4 nun that maintained reading ranges of about 3 m for the antenna in free space and 7 m for the antenna on a metallic surface.
