WebSpiral Antennas. Antenna Theory (Home) Spiral antennas belong to the class of "frequency independent" antennas; these antennas are characterized as having a very large bandwidth. The fractional Bandwidth can be as high as 30:1. This means that if the lower frequency is 1 GHz, the antenna would still be efficient at 30 GHz, and every … A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that is usually fed by a balanced source or feeding a balanced load. Within this physical description there are two (possibly three) distinct types: • Large loop antennas (or self-resonant loop antennas or full-wave loops) have a perimeter close to one or more whole wavelengths at the operating frequency, which makes them self-resonant a…

Webantennas are shown in Section 10.2 to have stable directional properties far from the antenna (the antenna far field), and different directional properties closer than ~/2λπ (the antenna near field). In Section 10.3 these properties are related to basic metrics that characterize each antenna, such as gain, effective area, and impedance. http://www.vlf.it/poggi4/stealthantenna.html WebA loop antenna is a coil carrying radio frequency current.
