Compact Metamaterial-Based Tunable Zeroth-Order Resonant Antenna with Chip Variable Capacitor
This letter presents a compact metamaterial-based tunable zeroth-order resonant antenna. It is based on the double-negative unit cell with a function of tunable inductance realized by a varactor and impedance convertor in the shunt branch. The resonant frequency of the designed antenna ranges from 2.31 to 3.08 GHz, depending on the capacitance of the used varactor. Its size is very compact (0.0...
متن کاملMetamaterial Antennas Used for Wireless Applications
In this review article, different structures of monopole antennas based on metamaterial concepts which have been developed for various wireless applications are presented. The antennas designed for wireless applications must be broad band, low profile, small size and have better performance. Monopole antennas embedded with Artificial magnetic conductors (AMC), Electromagnetic band gap structure...
متن کاملMetamaterial Antennas and Applications- A Review
In this paper applications of metamaterial has been discussed. Metamaterial is an artificial material which exhibits unique properties which cannot be achieved from the conventional materials. Metamaterial can be used as antenna substrate, feed networks, phased array antenna and antenna ground planes. Metamaterial can be used to increase the gain directivity and bandwidth of antenna. In body we...
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...
متن کاملMetamaterial-Based Antennas: Research and Developments
A brief review of metamaterials and their applications to antenna systems is given. Artificial magnetic conductors and electrically small radiating and scattering systems are emphasized. Single negative, double negative, and zero-index metamaterial systems are discussed as a means to manipulate their size, efficiency, bandwidth, and directivity characteristics. key words: metamaterials, electri...
