Optical Antenna Gain 2: Receiving Antennas

Applied Optics, 1974
Expressions are derived for the gain of a centrally obscured, circular optical antenna when used as the collecting and focusing optics in a laser receiver which include losses due to (1) blockage of the incoming light by the central obscuration, (2) the spillover of energy at the detector, and (3) the effect of local oscillator distribution in the case

The Receiving Antenna

Proceedings of the IRE, 1944
After a discussion of the general problem of coupled antennas, the distribution of current in a center-loaded receiving antenna with its axis in the plane of a linearly polarized electric field is derived. Distribution curves are shown for a wide range of lengths, thicknesses, and load impedances.

Receiver antenna array

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
Our aim is to develop a microwave receiver antenna system, which can form its radiation pattern (main lobe direction, null-point direction, structure of the side lobes), measure the direction of the RF source in milliseconds. In this paper we will show the theoretical background of the antenna system, the build-up of the realized system and some ...
