An antenna is a metallic structure that captures and/or transmits radio electromagnetic waves. Antennas come in all shapes and sizes from little ones that can be found on your roof to watch TV to really big ones that capture signals from satellites millions of miles away. The antennas that Space Communications and Navigation (SCaN) uses are a special bowl shaped antenna that focuses signals at ...

Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional, or high-gain, or "beam" antennas).
Before we can design an antenna or discuss antenna types, we must understand the basics of antennas, which are the fundamental parameters that characterize an antenna.
That's more or less what an antenna (sometimes called an aerial) does: it's the metal rod or dish that catches radio waves and turns them into electrical signals feeding into something like a radio or television or a telephone system. Antennas like this are sometimes called receivers.

Antenna Info With cable and satellite subscriptions becoming ever more expensive, many households are considering using an antenna to receive television programming for free from their local broadcasters. AntennaWeb can help you become a more informed consumer before shopping for an antenna. This page provides information about over-the-air antennas, the CTA’s color-coded labeling standard ...
Learn the antenna definition, understand the function of an antenna, and discover how radio signals are transmitted. Explore the different types of antenna and their uses.
An umbrella antenna is an elaborated and expanded version of a 'T' antenna; it is a very large wire transmitting antenna used on VLF bands for VLF time signals or long-range submarine communications.
Slot antenna X-band slotted waveguide marine radar antenna on ship, 8–12 GHz. The antenna radiates a narrow vertical fan-shaped beam of microwaves, scanning the entire 360° water surface around the ship with each rotation. Cross section of similar marine radar antenna with part of plastic radome removed, showing slots in waveguide.

Martyn from “across the pond” writes that after wall-mounting their LG G-Series OLED, there was some kind of signal interruption between their antenna (or aerial) and their TV. After hooking up their ...
BGR on MSN: Do more antennas on a router mean better signal quality?
Some wi-fi routers have loads of external antennas, others seem to have none, so it's important to understand how the number of antennas impact signal quality.
If you want to cut the cord but keep live TV, you need the right antenna to tune into over-the-air broadcasts. Here's what you need to know, along with our top picks.
Get sharp pictures from your local stations with TV antennas from Best Buy. Shop indoor/outdoor digital TV antennas or an amplified HDTV antenna for indoor use.
We recommend researching beforehand to determine what range of antenna you need, and whether you want an indoor model or an antenna made for outdoor installation.

An antenna is a specialized transducer that converts electric current into electromagnetic (EM) waves or vice versa. Antennas are used to transmit and receive nonionizing EM fields, which include radio waves, microwaves, infrared radiation (IR) and visible light.
Antenna radiating radio waves: The transmitter applies an alternating current (red arrows) to the rods, which charges them alternately positive and negative, emitting loops of electric field. The arrows of the loops get reversed each time the current changes polarity.
Buying Guide: The Best Digital TV Antennas for 2026 Your Location Matters Before you start shopping for an antenna, you should check to see which channels are available near you.
Antenna, component of radio, television, and radar systems that directs incoming and outgoing radio waves. Antennas are usually metal and have a wide variety of configurations, from the mastlike devices employed for radio and television broadcasting to the large parabolic reflectors used to receive
Antenna Fundamentals Let's get right down to the study of antennas and Antenna Basics. Suppose one day you're walking down the street and a kind but impatient person runs up and asks you to design an antenna for them. "Sure", you quickly reply, adding "what is the desired frequency, gain, bandwidth, impedance, and polarization?" Or perhaps you have never heard of (or are a little rusty) on the ...
An easy-to-follow explanation of how antennas transmit or receive radio waves and the various different kinds of antennas.
A log-periodic antenna is a directional antenna composed of multiple elements that function across a wide range of frequencies. Log-periodic antennas are typically dipoles arranged along their axis. These aerial types are particularly useful in applications that require variable bandwidths, antenna directivity and gain are priorities.
