Antenna measurements are critical in antenna design. This page links to the required equipment and processes that are utilized in measuring antenna paramters.
Electrical length. This came up in the section on transmission lines. It is the length or distance expressed in terms of wavelengths. Bandwidth: generally the range of frequencies over which the antenna system‘s SWR remains below a maximum value, typically 2.0.
An antenna is a device that couples currents to electromagnetic waves for purposes of radiation or reception. The process by which antennas radiate can be easily understood in terms of the way in which accelerating charged particles or time-varying currents radiate, which is discussed in Section 10.1.
The book provides a broad coverage of antenna types and phenomena, for operations at very low radio frequencies, as well as frequencies up to those of submillimeter wavelengths. Unlike most university-level antenna textbooks, it does not require prior skills in electromagnetic theory, sophisticated mathematics, or computer programming.
antenna is based on any number of parameters: specifically, the frequency or band of frequencies, location, directivity, and intended power range. This paper discusses some of the more important aspects of the End Fed Half Wave (EFHW) dipole antenna. The frequency band is HF (40 meters), and the intended power is 100 watts.
A fundamental list of antenna theory concepts, an antenna basics menu is given here. Topics include directivity, polarization, bandwidth, impedance, frequency bands, all things necessary for an understanding of antenna theory, antenna basics and antenna fundamentals.
This handbook presents basic propagation theory, the fundamentals concerning antennas, and the design and use of tactical hiqh frequency and very high fvtquency antennas.
