Abstract :
A printed reflector-backed dipole antenna with printed loops connecting the two arms of the dipole is proposed. The antenna with a very low profile of 0.05λ0 exhibits wide impedance bandwidth and high antenna gain. It is attractive to be used in an array environment. Experimentally, a 50-element antenna array is fabricated and measured. It achieves a wide impedance bandwidth of 12.5% covering the 57-64GHz frequency band. Over this band, the measured antenna gain is ranged from 22.5-25.2dBi. The measured radiation pattern has low cross-polarization of less than -30dB and back lobe of smaller than -31dB. This design is very low cost in fabrication as it is only made from a single-layer printed circuit board.
