Tunable periodic microstrip structure on GaAs wafer [PDF]

, 2009
A one dimensional tunable periodic structure in microstip technology on gallium arsenide (GaAs) substrate is numerically investigated. The unit cell contains a number of patches positioned between the ground plane and the microstrip line.

Wideband Circularly Polarised Metasurface Microstrip Patch Antenna Using Characteristic Mode Analysis

IET Microwaves, Antennas & Propagation
A double‐layer wideband circularly polarised (CP) metasurface (MTS) antenna is proposed. The MTS consists of a 4 × 4 L‐shaped patch array. The modal behaviours of the proposed MTS are investigated using the characteristic mode theory.

Left-Handed Metamaterial (LHM) Structure Stacked on a Two-Element Microstrip Antenna Array

International Journal of Technology, 2016
Antenna can be one of the largest components in a wireless device; therefore antenna miniaturization can reduce the overall size of wireless devices. One method used to reduce the element size of an antenna is by using meta material structures.
