Lower Bound for the Radiation $Q$ of Electrically Small Magnetic Dipole Antennas With Solid Magnetodielectric Core
A new lower bound for the radiation of electrically small spherical magnetic dipole antennas with solid magnetodielectric core is derived in closed form using the exact theory. The new bound approaches the Chu lower bound from above as the antenna electrical size decreases. For , the new bound is lower than the bounds for spherical magnetic as well as electric dipole antennas composed of impres...
متن کاملMinimum Q of Electrically Small Antennas: a Critical Review
This paper seeks to succinctly e aluate and summarize the large body of literature on the radiation Q of electrically small antennas. The alidity of the different analytic models is discussed, with key Q-dependent physical properties compared with experimental data and numerical simulations. 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 172 177, 2001.
متن کاملSMALL ANTENNAS Basic Principles of Electrically Small Antennas
E lectrically small antennas have been an important part of communications engineering since the beginning. Whether they are small compared to the extremely long wavelengths used at the lowest radio frequencies, or intended to save space in GHz-range wireless devices, the basic principles are the same. This tutorial will review those principles, with primary attention to describing the performa...
متن کاملCharacterization of a Wideband, Low-q, Electrically Small Antenna
Using numerical and experimental techniques, a wideband, low-Q, electrically small antenna design is characterized as a function of frequency and the relati e phasing between antenna elements. The antenna demonstrates wideband operation, with a radiation Q approximately a factor of 20 below the Q-limit established by Chu for electrically small, omnidirectional antennas. 2000 John Wiley & Sons, ...
متن کاملMetamaterial-Based Efficient Electrically Small Antennas
A metamaterial paradigm for achieving an efficient, electrically small antenna is introduced. Spherical shells of homogenous, isotropic negative permittivity (ENG) material are designed to create electrically small resonant systems for several antennas: an infinitesimal electric dipole, a very short center-fed cylindrical electric dipole, and a very short coaxially-fed electric monopole over an...
