Fabrication and measurement of miniaturized Z‐shaped corrugated‐type patch antenna for WLAN

Abstract

This paper presents the characteristics of the miniaturized Z‐shaped meander‐type antenna realized for 5.25‐GHz wireless LAN systems. The proposed antenna consists of the modified meander line, corrugated shape, and shorting pin with coaxial feeding on the two‐layered (air and FR4) substrate, which forms the letter “Z.” This proposed antenna has equivalent performance with about 44.87% of size reduction with respect to conventional antennas. Its maximum measured impedance bandwidth (−10‐dB below) is approximately 300 MHz (5.05–5.35 GHz) or 5.76%, which meets to the bandwidth requirement of WLAN (5.15–5.35 GHz) systems. Details of the proposed antenna are described and experimental results of constructed prototypes also are presented. © 2006 Wiley Periodicals, Inc.
