Ka-band holographic antennas.

Kathia. Lévis
In this thesis holographic antennas are investigated as an alternate 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 excessive losses associated with conventional phased array feeds. The main purpose of this work is to apply optical holography theory at microwave frequencies in the design of Ka-band holographic antennas. As with optical frequencies, the interference pattern...
