Circularly polarized strips integrated microstrip antenna for energy harvesting applications," Microwave and Optical Technology Letters, vol.
The obtained frequency (impedance) bandwidth is found to be wider than the mentioned single
circularly polarized structures [2, 3] having 1.4% bandwidth at most.
Figure 1 illustrates the basic configuration of the shared-aperture dual
circularly polarised microstrip antenna.
A novel compact
circularly polarized square-ring microstrip antenna with vertical slotted ground for UHF RFID has been successfully implemented, which is designed as Z-shaped and capacitive coupled structure.
Excited by the
circularly polarized beam, the transmitted left-circularly polarized (LCP) and right
circularly polarized (RCP) components of the second harmonics are shown in Fig.
Caption: Image displayed using
circularly right-polarised light.
Figure 1(a) shows the geometric layout of a proposed single-feed
circularly polarized slotted rectangular microstrip patch antenna.
To design and manufacture
circularly polarized isotropic antennas, the signals of readers were divided into two signals of the same magnitude and an incidence difference of 90[degrees].
However, most of the proposed dual-band dual-sense
circularly polarized slot antennas in present literatures have relatively complex structures with several optimized parameters in order to achieve orthogonally circular polarization at two different working frequencies.
In Section 3, based on the equivalent circuit model, we describe the optimization of the metal grating for application to the 2 x 2
circularly polarized sub-array considered in our work.
Hodara proposed the external magnetic field can slow down attenuation of the right-hand
circularly polarized electromagnetic wave in plasma [12].
Microstrip antennas have enjoyed proliferate use in many
circularly polarized applications due to their low-profile light weight and useful radiation characteristics (Bao & Ammann, 2007).
