Its an antenna that can operate in vertical as well as horizontal polarization. Dual polarized antennas are often used in 802.11n devices to enable multi-thread communication. This enables the device to transmit data on one polarization and receive data on the other simultaniously. The advantage of this is that multi-thread communication can be achieved with the use of one antenna instead of using two independent (and opposite polarized) antennas for the same result. Obviously all the networking equipment in the wireless network must be multi-thread complaint for this to work.

Are cross-element Yagi antennas always circularly polarized?
No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna. No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna.
Is a wave length horizontal or vertical?
If you can visualize whipping a length of rope tied to a fixed spot back and forth, you can then perfectly visualize radio frequency waves. If you whip the rope up and down the wave is vertically polarized. If you whip it back and forth horizontally, it is horizontally polarized. If you use a set of "rabbit ears" (dipole) to transmit a signal and hold it so the antenna points up and down, the radiated waves will be vertically polarized. To receive vertically polarized waves best, you need to use a vertically polarized antenna. The same holds true for horizontally polarized systems. This is a very simple but applicable explanation. There are other kinds of polarization such as "circular" as used in FM broadcasting and space communications. Just remember that the transmitting antenna's design determines the polarization of a radiated wave. See the ARRL Handbook 621.384 in your library for more detail.
What is the purpose of the ortho-mode-transducer in a SHF antenna?
The ortho-mode transducer (OMT) in a super high frequency (SHF) antenna serves to separate and combine signals propagating in different polarization modes, typically vertical and horizontal. This allows for efficient handling of dual-polarized signals, improving antenna performance by reducing cross-polarization interference. By enabling the simultaneous transmission and reception of signals with different polarizations, the OMT enhances bandwidth utilization and overall communication efficiency in satellite and radar applications.
Are phospholipids polarized molecules?
Yes, phospholipids are polarized molecules because they contain both a hydrophilic (polar) head and hydrophobic (nonpolar) tails. This dual nature allows them to form the lipid bilayer structure in cell membranes.
Why vertical polarized wave is preferred over horizontal polarized wave in mobile radio communication?
1). Reflection of vertically polarized waves is less efficient, so vertical polarization is less susceptible to multipath fading due to ground-based reflection. 2). In order to avoid directional effects due to the radiation pattern of the receiving antenna (losing the mobile signal when the car turns a corner), the antenna wants to be vertical. That generally means vertical electrical polarization.
What are the features of helical antenna?
the features are :-1.It has a wide bandwidth2.Easily constructed3.Has real i/p impedence.4.Can produce circularly polarized field.
What is single polarized antenna means?
A single polarized antenna is designed to transmit or receive electromagnetic waves with a specific polarization, either horizontal or vertical. This means that the electric field of the emitted or received signal oscillates in only one plane. Single polarization is often used in communication systems to enhance signal quality and reduce interference, as both the transmitting and receiving antennas need to match in polarization for optimal performance.

What Dual Band Antenna is used for?
A dual-band antenna is designed to operate on two distinct frequency bands, making it versatile for various communication applications. Commonly used in wireless networks, such as Wi-Fi and cellular systems, it enables devices to connect to multiple frequency ranges, improving signal quality and reliability. Additionally, dual-band antennas are often utilized in smartphones, routers, and other wireless devices to enhance connectivity and performance.
