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 ...
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 tunable metamaterial is a metamaterial with a variable response to an incident electromagnetic ... It has applications for microwave circuits and antennas. [18] [19
The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
The Tonal 2 is an in-home, all-in-one gym focused on resistance training. The device itself is like a thick mirror, with adjustable metal arms that unfold for use and then tuck away for storage.
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 ...
