Linearly polarized antenna
NettetLinearly polarized antenna An antenna that radiates linearly polarized waves, which are waves in which the electric field vector stays parallel to a line in space as the waves travel. Low frequency (LF) The frequency band of 30-300 KHz. RFID systems in this band typically operate at 125 KHz or 134 KHz. NettetNormalized Radiation Pattern for Microstrip (Patch) Antenna. The directivity of patch antennas is approximately 5-7 dB. The fields are linearly polarized, and in the horizontal direction when viewing the microstrip antenna as in Figure 1a (we'll see why in the next section). Next we'll consider more aspects involved in Patch (Microstrip) antennas.

Nettet11. apr. 2024 · A novel dual linearly-polarized magnetoelectric (ME) dipole antenna with wide bandwidth is presented in this letter, where two orthogonally placed Г probes are utilized to realize dual polarizations. In particular, four heptagonal patches are first adopted in lieu of the four conventional rectangular patches to obtain a wider bandwidth. In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. The term linear polarization (French: polarisation rectiligne) was coined by Augustin-Jean Fresnel in 1822. See polarization and plane of polarization for more information. The orientation of a linearly polarized electromagnetic wave is defined by the direction of the ele…
For a linearly-polarized antenna, this is the plane containing the electric field vector (sometimes called the E aperture) and the direction of maximum radiation. The electric field or "E" plane determines the polarization or orientation of the radio wave. For a vertically polarized antenna, the E-plane usually coincides with the vertical/elevation plane. For a horizontally polarized antenna, the E-Plane usually coincides with the horizontal/azimuth plane. E- plane and H-plane should b… NettetThis paper presents two designs of high-efficiency polarizer reflectarray antennas able to generate a collimated beam in dual-circular polarization using a linearly polarized …
