Terms starting with ‘P’
- Parabolic Antenna
- An antenna that uses a parabolic reflector (a curved surface with the cross-sectional shape of a parabola) to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. These…
- Parasitic Element
- A conductive element, typically a metal rod, which is not electrically connected to anything else. The purpose of the parasitic elements is to modify the radiation pattern of the radio waves emitted by the driven element, directing them in a beam…
- Pentaband Antenna
- An antenna that combines 4-band GSM and W-CDMA 2100 to receive and transmit signals in all cellular bands. These antennas can be used in mobile, machine-to-machine, laptop, automotive, and all portable device applications for devices operating on…
- Periscope Antenna
- An antenna configuration in which the transmitting antenna is oriented to produce a vertical radiation pattern. A flat or off-axis parabolic reflector, mounted above the transmitting antenna, is used to direct the beam in a horizontal path toward…
- Phased Array
- An antenna array is a group of multiple active antennas coupled to a common source or load to produce a directive radiation pattern. Usually, the spatial relationship of the individual antennas also contributes to the directivity of the antenna…
- Planar Array
- An antenna in which all of the elements, both active and parasitic, are in one plane. A planar array provides a large aperture and may be used for directional beam control by varying the relative phase of each element. A planar array may be used…
- A communications channel running from one point to several other points.
- A long-range wireless network between two points. Point-to-point wireless networks use directional antennas.
- In a specified direction from a wireless antenna and at a point in its far field, is the polarization of the (locally) plane wave which is used to represent the radiated wave at that point. At any point in the far-field of an antenna the radiated…
- Power Handling
- Is the ability of a Wireless LAN antenna to handle high power without failure. High power in antenna can cause voltage breakdown and excessive heat (due to conductor and dielectric antenna losses) which would result in an antenna failure.
- Printed Antenna
- All antennas made by means of a printed circuit process.
- Propagation Mode
- The manner in which radio signals travel from a transmitting antenna to a receiving antenna (such as ground wave, sky wave, direct wave, ground reflection, or scatter).
