Ka-band dipole holographic antennas
Dipole holographic antennas are investigated as an alternative technology to reflectors and microstrip phased arrays for use in Ka-band applications. These antennas combine the advantages of low-profile printed technology with an unconstrained feed to avoid the excessive losses associated with conventional phased array feeds. Various single-layer and two-layer designs are described. Measurements show that the efficiency of the holographic antennas is comparable with that of Ka-band passive phased arrays with conventional microstrip feeds. However, holographic antennas are less complex than conventional microstrip phased arrays, making them a good candidate for low-cost LMCS and SATCOM terminals.
