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; Antennae Galaxies, the name of two colliding galaxies NGC 4038 and NGC 4039
The optical antenna consists of three main parts: the ground plane, the optical resonance cavity, and the antenna. The antenna absorbs the electromagnetic wave, the ground plane acts to reflect the light back towards the antenna, and the optical resonance cavity bends and concentrates the light back towards the antenna via the ground plane.

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.

Dating experts say "sticky eyes" − which isn't actually all that new − is a great way to signal openness and interest to a stranger at a bar, party or other social setting.
The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
