Abstract

A simple and compact dual-frequency monopole antenna is presented and investigated and which is suit for the applications of WLAN IEEE802.11b/g (2400-2484 MHz) and IEEE802.11a (5150-5350 MHz). The screen-print technology is used, to print the CPW-fed dual-frequency antennas on AI₂O₃ ceramic substrates. The proposed antennas have the advantages of small size (29 mmx20 mmxl mm), dual-frequency operation (2.4 and 5.2 GHz), good radiation characteristics (near omni-directional radiation pattern in y-z plane) and large gain (1.29 dBi at 2.35 GHz and 3.96 dBi at 5.27 GHz).
