Antenna designs incorporating metamaterials can improve the radiated power of an antenna. The newest metamaterial antennas radiate as much as 95 percent of an input radio signal. Standard antennas need to be at least half the size of the signal wavelength to operate efficiently. At 300 MHz, for instance, an antenna would need to be half a meter ...
In 1984, Dr. Cendes founded Ansoft Corporation to design and develop high performance EDA software. He served as its chairman and chief technology officer until 2008, when Ansys acquired Ansoft. [5] [6] Ansoft originally sold HFSS as a stand-alone product under an agreement with Hewlett-Packard. It was also bundled into Ansoft products. [5]

Metamaterial antennas are a class of antennas that use metamaterials to improve performance. [15] [21] [85] [86] Demonstrations showed that metamaterials could enhance an antenna's radiated power. [15] [87] Materials that can attain negative permeability allow for properties such as small antenna size, high directivity and tunable frequency ...
A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the effective length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic radiation within a given total surface area or volume.
Metamaterial Surface Antenna Technology (MSAT) by Kymeta offers a unique perspective on addressing challenges in satellite communications. By incorporating high-birefringence liquid crystals, metasurfaces, and holographic beamforming , MSAT enables the development of electronically-scanned antennas that effectively address bandwidth, efficiency ...
The EM metamaterial as an artificially designed transmission medium, has so far delivered desired responses at frequencies from the microwave through to the near visible. [6] The introduction of a natural semiconductor material within or as part of each metamaterial cell results in a new design flexibility.
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
