A broadband Wilkinson balun using microstrip metamaterial lines
(2005)A metamaterial balun that converts a single-ended input to a differential output over a large bandwidth is presented. The device also exhibits excellent return loss, isolation, and through characteristics over the same ...

A Compact Multiband Printed Dipole Antenna Loaded with Two Unequal Parallel NRI-TL Metamaterial Unit Cells
(2015)A negative-refractive-index transmission-line (NRI-TL) metamaterial-loaded dipole antenna is proposed, which has a fully printed configuration and exhibits multiband performance. The antenna consists of a conventional ...

An investigation of printed Franklin antennas at X-band using artificial (metamaterial) phase-shifting lines
(2008)Non-radiating artificial phase-shifting lines are constructed using conventional positive-refractive-index (PRI) transmission lines (TL) and the recently developed negative-refractive-index (NRI) transmission lines. The ...

Method of decoupling and independently tuning the second mode of a microstrip-fed slot antenna using series inductive loading
(2013)In this letter, a systematic method of decoupling and tuning the second mode of a half-wavelength microstrip-fed slot antenna is presented. This is achieved by introducing a series lumped inductive load at the center of ...

Method of isolating and tuning the two dominant modes of a printed inverted-f antenna
(2013)A systematic method for decoupling and increasing the tunability of the first and third-order resonant modes of a compact, printed inverted-F antenna is presented. By identifying and utilizing surface-current symmetry in ...

Miniaturized Planar Yagi Antenna Utilizing Capacitively Coupled Folded Reflector
(2017)The analysis and design of a unidirectional and wideband printed Yagi antenna with miniaturized size using a capacitively coupled reflector is presented. Reflectors have been widely used for canceling back radiation of ...

A multiband printed inverted-F antenna using current symmetry
(Institute of Electrical and Electronics Engineers Inc., 2014)A compact multiband antenna is presented, which consists of a planar inverted-F structure with two branches placed at key locations along the main radiating arm, and a microstrip-coupled slot in the ground plane. A systematic ...

Planar antennas for compact multiband transceivers using a microstrip feedline and multiple open-ended ground slots
(2015)Two planar antennas for compact multiband transceivers are presented, that employ an open-ended microstrip feedline that couples to multiple open-ended ground slots. The effect of separately introducing each of the slots ...
