Abstract
AbstractThe article is concerned with the extremely low‐profile foam dielectric five‐arm folded dipole antenna, which was developed and manufactured. The aforementioned antenna is situated on the metal screening plane and is used for UHF RFID of dielectric objects. It is designed with a complex input impedance Zin = 22 + j195 Ω at 866 MHz. Its efficiency was evaluated by Wheeler cap method with and without enclosed a human body phantom, it accounts for ∼40%, irrespective of whether the phantom is enclosed or not. The preliminary test of the identification range in buildings corridor was performed. The identification range reaches as far as 15.8 m. © 2010 Wiley Periodicals, Inc.
