It is frequently stated that using the plural antennae for electrical aerials is incorrect. Those who say this believe that there is a grammatical rule that the plural in the context of radio is antennas and in the context of biology (insect feelers for example) the plural is antennae. This may have crystallised into a firm rule in the US, but ...
Antenna (radio), also known as an aerial, a transducer designed to transmit or receive electromagnetic (e.g., TV or radio) waves Antenna types, a list of the many different types of radio and microwave antennas
The antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface area) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna which radiates equal power in all directions.
Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
In radio and electronics, an antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver.
Earth station at the satellite communication facility Raisting Earth Station in Raisting, Bavaria, Germany. Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies.
A horn antenna has a flaring metal horn attached to a waveguide. It is a simple antenna with moderate gain of 15 to 25 dBi, used for applications such as radar guns, radiometers, and as feed antennas for parabolic dishes. Slot Consists of a waveguide with one or more slots cut in it to emit the microwaves. Linear slot antennas emit narrow fan ...
Although the everyday meaning of plural is "more than one", the grammatical term has a slightly different technical meaning. In the English system of grammatical number, singular means "one (or minus one)", and plural means "not singular". In other words, plural means not just "more than one" but also "less than one (except minus one)".
