Compound Metacurl Antenna With C- and N-Type Metaatoms
TL;DR: A novel metacurl antenna composed of C-type metaatoms and N-typeMetaatoms is analyzed, which reveals that replacement with an appropriate number of N- typemetaatoms increases the maximum LHCP gain, resulting in a balancing of LH CP gain and RHCP gain.

Unified particle swarm optimization with random ternary variables and its application to antenna array synthesis
Guolong He,Bin Wu +1 more
TL;DR: In this paper, a modified particle swam optimization (PSO) algorithm is proposed in order to deal with real and integer variables in a unified manner, which can accelerate the speed of convergence and lead to improved topology exploration capability.
Journal ArticleDOI
Multiband–multislot planar antenna based on small loop-radiator
TL;DR: In this article, a multiband-multislot planar antenna is proposed based on the small loop-and slot radiators, showing multiple resonances, which can be shifted to lower or higher frequencies depending on the slots length and width, as well as the magnetic coupling among them.
