Abstract

This article describes the novel design of printed and doubled‐sided dipole array antennas with parallel reflector in the application of 2.4 GHz ISM band operated in WiFi access point. The printed dipole array antenna consists of one dipole array arranged back to back and can be easily formed by printing on both sides of a dielectric substrate and is suitable for integration with monolithic microwave integrated circuit (MMIC) module. Based on the matching theory, a 50 Ω microstrip feed line with open stub matched circuits is determined to possess high performance. The all extremely wideband or high gain dipole antenna array for value of standing wave ratio (VSWR) ≤ 1.5 has been successfully implemented and achieved. Simulator IE3D is used to verify our analysis. Both simulated and measured data are much identical. The designed 8‐element printed dipole array antenna without and with a reflector metallic ground plane achieves a gain of 8.5–9.3 dB with a 200 MHz bandwidth and a gain of 11.4–12.3 dB with a 80 MHz bandwidth, respectively. © 2008 Wiley Periodicals, Inc.
