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.
