Radiation patterns of interfacial dipole antennas

Radio Science, 1982
The radiation pattern of an infinitesimal electric dipole is calculated for the case where the dipole is vertically located on the plane interface of two dielectric half spaces and for the case where the dipole is lying horizontally along the interface.

Radiation Pattern Reconfigurable Horn Antenna

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
A radiation pattern reconfigurable horn antenna (RHA) capable of steering its main beam in three directions in the semi-sphere space corresponding to θ ∈ {−25°, 0°, 25°}, is presented. The RHA consists of a driven X-band (10 GHz-11.5 GHz) horn antenna, a reconfigurable parasitic layer and a dielectric loaded truncated pyramid (DLTP). The surface of the

On Polarization Coloration of the Antenna Radiation Pattern

Journal of Communications Technology and Electronics, 2018
Problems arising in the course of practical implementation of the principles and of radio polarimetry are considered. It is shown how to ensure “polarization coloration” of the radiation pattern. The influence of various interferences and the noise, which inevitably exist during information transmission, is considered.

Radiation pattern control in microstrip antennas

Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering, 2002
The far field radiation from a microstrip antenna is investigated numerically. Such an antenna has several electrical and geometrical parameters that can be used in shaping its radiation patterns. Among these the ground plane size and shape have the least effect on the antenna circuit parameters and may be used as the controlling parameters.

Scanning synthetic radiation pattern antennas

Radioelectronics and Communications Systems, 2010
It is proposed conception of development of new type transmitting-receiving scanning antennas, which are called antennas with synthetic radiation pattern. It is based on application of movement of radiating (receiving) element together with synthesizing of radiation pattern (RP) by means of SAR for processing of recorded information about radiated and ...

Plotting satellite antenna radiation patterns

IEEE Antennas and Propagation Magazine, 1991
Approaches for visualizing satellite antenna radiation patterns are presented. Gain-level contours drawn over a geographical map give the clearest quantitative information. A three-dimensional surface plot displays the qualitative shape of the radiation pattern more naturally.

Recording of dynamic antenna radiation patterns

IEEE Transactions on Antennas and Propagation, 1973
A concept is presented for recording antenna radiation patterns as functions of two parameters simultaneously. An implementation of the technique results in a significant savings in the measurement time required to document antenna performance as a function of the particular pair of parameters of interest.
