A variety of antennas have been engineered with metamaterials (MTMs) and metamaterial-
inspired constructs to improve their performance characteristics. Examples include …

Several metamaterial-inspired, electrically small, near-field resonant parasitic antennas are
presented. Both electric and magnetic couplings to the parasitic are compared and …

Both 300-and 570-MHz versions of an electrically small, coaxially fed Z antenna were
designed and tested. These two cases demonstrate the ability to change the resonance …

Non‐Foster networks are those whose reactance has a negative slope with frequency, and
can thus overcome bandwidth limitations of many passive systems using their unique …

Summary Anytime‐wireless‐everywhere (AWE) aspirations for Internet‐of‐things (IoT)
applications to be enabled through current 5G and evolving 6G and beyond ecosystems …

Traditional impedance-matching methods typically employ matching networks at the
antenna input terminals. Alternatively, the antenna may be embedded with a non-Foster …

The demand for miniaturized, broadband communication systems has created a need for
electrically small, broadband antennas. However, all passive electrically small antennas …

Several electrically small antenna systems that utilize the magnetic couplings between a
coaxially-fed semi-loop antenna and capacitively-loaded loop (CLL)-based near-field …

Metamaterial (MTM)-inspired antennas leverage techniques that have been developed over
the past decade for designing artificial materials whose electromagnetic properties can be …

Variations of the electrically small, resonant near-field parasitic Z antenna are investigated.
By introducing multiple near-field resonant parasitic elements, multiband systems are …
