Antenna miniaturization has been the subject of numerous studies for almost 70 years [1]-[4].
Early studies showed that a decrease in the size of an antenna results in a direct reduction …

Nonlinear transmission lines (NLTLs) have been increasingly studied to produce high power
microwaves (HPM) at higher repetition rates than conventional HPM devices without …

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

A compact tri-band planar monopole antenna is proposed that employs reactive loading and
a¿ defected¿ ground-plane structure. The reactive loading of the monopole is inspired by …

A wideband and compact planar antenna is proposed using a doubly resonant transmission-
line metamaterial (TL-MTM) structure. The antenna consists of two TL-MTM arms that …

This paper presents the design and analysis of compact coplanar waveguide (CPW)-fed
zeroth-order resonant (ZOR) antennas. They are designed on a CPW single layer where …

A novel compact, planar, and coplanar waveguide (CPW)-fed dual-band antenna is
designed and proposed using composite metamaterial. Such composite metamaterial …

We studied electrically small resonant antennas composed of split ring resonators (SRR)
and monopoles. The antennas considered have the same ring radius, but slightly different …

A novel reconfigurable microstrip antenna with radiation pattern selectivity and polarization
diversity is presented in this letter. A four-way power divider made by three Wilkinson power …

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