We present a modified quasi-Yagi antenna for use in WLAN access points. The antenna uses a new microstrip-to-coplanar strip (CPS) transition, consisting of a tapered microstrip input, T-junction, conventional 50-ohm microstrip line, and three artificial transmission line (ATL) sections. The design concept, mode conversion scheme, and simulated and experimental S-parameters of the transition are discussed...
In recent years, ultra-high-frequency (UHF) radio frequency identification (RFID) systems have drawn more and more attentions in a wide variety of applications such as retail item management, access control system, electronic toll collection, and etc. By incorporating with a commercial RFID reader, it has been noted that the phased array antenna can be implemented in a RFID system to either control...
In this paper, a miniaturized Wilkinson power divider with harmonic suppression characteristics is proposed for ultra-high-frequency (UHF) radio frequency identification (RFID) applications. This design consists of four sections of a recently proposed planar artificial transmission line (ATL). The experimental results reveal that the proposed power divider features low insertion loss and compact size...
In this paper, a new planar miniaturized diplexer is proposed for GSM/DCS dual band cellular phone applications. The design is composed of four sections of a recently proposed planar artificial transmission line (ATL) which is used to replace the conventional series quarter-wavelength transformers and the shunt open-circuited stubs. The experimental results reveal that the proposed diplexer features...
