Antennas for communications

IEEE Communications Magazine, 1981
The radio spectrum suitable for communications is limited, and even with global allocation and management, the problem of spectrum congestion continues to increase. This has led to more and more being demanded from antennas so that they play their part in minimizing the problem.

Spiral antennas and antenna arrays

2005 IEEE Antennas and Propagation Society International Symposium, 2005
The planar square-Archimedean spiral located at the center of a dipole has been demonstrated as a valuable passive antenna element in the upper MM-wave and THz regions between about 100 GHz and 2 THz (Bjarnason, E. et al., Appl. Phys. Lett., vol.85, p.3983, 2004).

Comparative Study of a Metal Antenna, a Liquid Antenna and a Plasma Antenna

2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP), 2020
In this paper, three different types of antennas including the metal antenna, the liquid antenna and the plasma antenna are investigated. Comparative studies are performed and the results are discussed. The results show that the metal antenna has a higher efficiency while the plasma and the liquid antennas have a better reconfigurability.

Antenna Analyses: Objects Near Antennas and Microstrip Antennas.

1980
Abstract : In this report the research work encompassed two classes of antenna analyses. One was an investigation of the effects of a nearby object upon an antenna and its performance and the other was a study of the center-fed, circular microstrip antenna.
