Antenna dimension: Dipoles of a dual-polarized antenna in different polarization directions are sufficiently isolated even if the dipoles are overlapped. Therefore, a dual-polarized antenna is no larger than a single-polarized antenna.翻訳 コレクション ドキュメントのダ...
To learn more about RFID Antenna Polarization, read our article - Circular Polarization vs. Linear Polarization: Which is the Right RFID Antenna?Circularly-Polarized AntennasA circularly-polarized antenna transmits RF waves that continually rotate between horizontal and vertical planes in order to give ...
There are some exotic propagation modes that operate differently, but for a terrestrial LOS path, the signal polarization tends to stay relatively constant. [...] for this case, it is fairly important to be able to respond to the appropriate polarization. [...] the dipole requires two ...
A helical antenna is considered as an excellent feed for circular polarization. It can particularly serve as a good feed for small offset dishes in the case of satellite applications. Helical antennas operating in normal mode are used for mobile radios as well as in broadcasting antennas. Helical...
reception. The optimal antenna size is one-half or one-quarter of a wavelength, so an audio frequency of 3000 Hz needs a wavelength of 100 km and a 25-kilometer antenna. Instead, with an FM carrier of 100 MHz with a wavelength of 3 meters, the antenna only needs to be 80 cm long....
Antenna effective aperture, however, is not always directly related to how big or small an antenna is. Shape, antenna type, polarization, power, and other design elements have enabled small antennas with apertures similar in size to physically bigger systems. Aperture size is just one important ...

One side expands outward, and the other side is parallel to the plane of the original waveguide. It can be divided into E-plane sector horn antenna and H-plane sector horn antenna. [conical horn] Conical horn antenna has a circular section, which is usually used with circular waveguide and...
What is a carrier wave?Question:What is a carrier wave?Wave:Wave is a manifestation of disturbance or oscillation that propagates through space and time and is accompanied by an energy transfer without the transfer particles. Some practical applications of waves include sound and light waves.Answer...
