Wideband printed and double-sided dipole pair antennas with a parallel reflector

The use of printed and doubled-sided dipole pair wideband antennas with parallel reflector In application of 2.4 GHz ISM band operated In WLAN access point has been demonstrated in this paper. 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, which includes of a 5012 microstrip feed line with open stub matched circuits is designed. Properties of the radiator as an array element have also been Investigated. Simulator IE3D is used to verify our analysis. Both simulation and measured data are pretty matched. According to the measured results, the measured gain for 2.45GHz band is between 5.3 and 7.0 dBi and the bandwidth with VSWR less than 1.5 is about 310MRz when the dipole array adds a reflector.
