Ant antennae: are they sites for magnetoreception? [PDF]
Journal of the Royal Society Interface, 2010 Migration of the Pachycondyla marginata ant is significantly oriented at138 with respect to the geomagnetic north-south axis. On the basis ofprevious magnetic measurements of individual parts of the body(antennae, head, thorax and abdomen), the antennae ...

Approximation of antenna diagram for BTS antennas
2011 34th International Conference on Telecommunications and Signal Processing (TSP), 2011This paper proposes a general formula for approximation of BTS (Base Transceiver Station) directivity characteristics. While computing gain from HPBW (half power beam width) in H and V plane, a H approximation and a V approximation formulas are suggested, in order to have a quick model for EMF (Electro Magnetic Field) and coverage analysis starting ...

This chapter reports design and analysis methods for planar antennas based on modulated metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by means of the interaction with a MTS having a spatially modulated equivalent impedance.

Large antennas and microwave antennas
2005Large antennas and microwave antennas, which form the subject of the remaining chapters of this book, are characterized by the property that their useful dimensions are very large compared with the wavelength involved. The word ‘large’ refers to the physical dimensions of the antenna (radio telescopes, for example) compared with which the wavelengths ...

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, 2005The 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).

Antenna Analyses: Objects Near Antennas and Microstrip Antennas.
1980Abstract : 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.

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), 2020In 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.
