a device that is used to send and receive signals
An antenna is a device used to receive or transmit radio, television, or other signals. It works by capturing electromagnetic waves, such as those sent by TV stations, radio stations, or cell towers, and converting them into electrical signals that can be processed by a television, radio, or other equipment. Antennas can be external, like a rooftop antenna for television, or built into devices, such as a smartphone. They are essential for receiving over-the-air broadcasts, wireless communications, and other forms of signal transmission.

one of a pair of jointed sensory appendages on the head of insects, crustaceans, or similar organisms, often used to detect touch, taste, or movement
An antenna is an appendage attached to the head of some animals, including insects, crustaceans, and some mollusks. They are primarily sensory structures used for detecting touch, smell, and taste. The antennae are composed of a series of segments called antennomeres, which are connected by flexible joints. The shape and size of antennae can vary widely between different species, with some being thin and elongated while others are short and stout. Antennae can also be modified for specific purposes, such as for use as weapons, or for attracting mates through pheromones. In insects, the antennae are also important for flight, as they help to stabilize the insect's orientation and sense changes in wind speed and direction. Overall, the structure and function of antennae vary greatly across different animal groups, but they are an important sensory organ for many organisms.
- The ant waved its antenna as it explored the ground.
