Broadband planar circularly polarised antenna for ultra-high frequency applications
(2014)A broadband circularly polarised (CP) antenna employing a deformed square loop radiator in combination with two spiraled monopoles is presented, for use in multiple ultra-high frequency applications. This combination of ...

Compact cpw-fed planar monopole antenna with wide circular polarization bandwidth
(2013)The design and implementation of a coplanar waveguide-fed planar monopole antenna with circular polarization and broadband operation is presented. The antenna operates in the Industrial, Scientific, and Medical (ISM) and ...

Enabling electromagnetic applications of negative-refractive-index transmission-line metamaterials part II
(Institute of Electrical and Electronics Engineers Inc., 2004)The 1-Dimensional (1-D) metamaterial phase-shifting lines presented in [1] can be used to develop compact and broadband, non-radiating, metamaterial feed-networks for antenna arrays. These can be used to replace 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 ...

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 ...
