✦ Synopsis

Abstract

In order to offer RFID services on mobile phones, the RFID reader must be embedded on the handset as a chip. However, the directional coupler was used as a ceramic passive component in conventional handsets. RFID system using an identical Tx/Rx carrier frequency has a significant volume limitation compared with active components. This article presents the directional coupler design for UHF RFID mobile reader using IPD (Integrated Passive Device) process. T and π‐type coupler with dimensions of 1.74 × 1.6 and 1.32 × 1.4 mm^2^ were assembled. © 2007 Wiley Periodicals, Inc.

## Abstract In this paper, a new array antenna composed of Koch fractal microstrip patches for the UHF‐band RFID reader is proposed. The investigation shows that the coupling factor of two fractal patches in the E‐plane is much larger than that in the H‐plane, and the coefficients are smaller than
