Wideband printed dipole antenna for wireless LAN

A wideband printed dipole antenna array is proposed for WLAN and Bluetooth applications. The proposed antenna array, consisting of two printed-strip dipoles, the arms of which are printed on opposite side of an electrically thin dielectric substrate and connected through a parallel strip-line, is presented. The printed strip dipole antenna element is simulated by Ansoft HFSS 8.0. Several prototype antennas are designed and fabricated. Broadband antennas with bandwidth greater than 12% for VSWR ≤1.5 operating near 3.5GHz are obtained. This antenna is a good candidate for operation at 2.4GHz, 3.5GHz, or 5.8GHz. The important advantages of these antennas are simplicity in structure, low cost, and ease of manufacture and production largely as printed circuits.
