Abstract
An RFID assembly that includes both a UHF patch antenna and an HF or LF loop antenna is provided. The patch antenna and the loop antenna are arranged inside a housing in such a manner that the loop antenna partially overlaps an end portion of the patch antenna, thereby forming an extension of the patch antenna. In this manner, a performance of the UHF patch antenna can be maintained despite decreasing the size of the same, while an interference between the patch antenna and the loop antenna can be suppressed, in particular, by providing a gap between the same.
