摘要：

This article describes a capacitive feed (C-feed) for small, low-profile linear antennas. A meander line, which is the radiating element, in such antennas with a metallic back conductor electromagnetically couples a metallic feed plate placed between the meander line and the back metal (ground). This antenna has a very small leakage current on the outer surface of the coaxial cable and can control the imaginary part of the input impedance. The impedance characteristics and the antenna gain of -10 dBi are discussed based on simulated and measured results, which demonstrate successful achievement in the impedance and antenna gain for a RFID tags etc. (C) 2010 Wiley Periodicals, Inc.
