1) Is Hertzian dipole linear polarization since theEfield is parallel with the orientation of the dipole and radiates out equally out in all Azimuth angle when placed vertically? 2) Same reason as above, a short dipole antenna is linear polarization? 3) Is a horizontally placed loop antenna li...
A novel polarization-reconfigurable aperture-coupled magnetoelectric (ME) dipole antenna is presented. By electronically controlling the state of switches between square patches and an additional strip of the ME dipole, the antenna is capable of switching the polarization among one linearly polarized (LP...
This letter proposes the development of a polarization-reconfigurable omnidirectional antenna combining a dipole and a loop radiators. The omnidirectional circular polarization (CP) waves can be generated in the azimuthal plane by adopting two metal probes act as the dipole and printed spoke-like metal...
It was found that some modifications of the traditional design lead to an essential improvement of the co-to-cross polarization ratio up to 40 dB. An improved design of a log-periodic dipole antenna with low cross-polarization level is described. Some recommendations regarding improvement of the ...

The proposed ME dipole is able to work in three different polarization states including one linear polarization and two orthogonal...
A new broadband circularly polarized quasi magnetic-electric dipole antenna with single feed is proposed. The electric dipole is a pair of metal strip while the magnetic dipole is a pair of vertical shorted metal plate. The currents on the electric and magnetic dipoles exhibits an inherent phase ...
To perform the measurement, we will use our test antenna as the source. Then we will use a linearly polarized antenna (typically ahalf-wave dipole antenna) as the receive antenna. The linearly polarized receive antenna will be rotated, and the received power recorded as a function of the an...
The conventional rectenna, composed of a receiving antenna and a rectifier circuit, usually operates at a pre-defined incidence angle, polarization, and frequency [1,2]. Therefore, they are not sufficient for harvesting ambient EM energy. The metasurface, a periodic array of metamaterial cells ...
The formation of dipole moments for two typical molecules: (a) molecule CO2 having no net permanent dipole moment and (b) molecule H2O having net permanent dipole moment. In the presence of an electric field F, the molecules carrying a permanent dipole moment will orient to align the ...
