1Antenna (radio) — Whip antenna on car …
2Antenna measurement — techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. Typical parameters of antennas are gain, radiation pattern, beamwidth, polarization, and impedance.The antenna pattern is… …
3Antenna tuner — An antenna tuner, transmatch, or antenna tuning unit (ATU) matches a transceiver with a fixed impedance (typically 50 ohms for modern transceivers) to a load (feed line and antenna) impedance which is unknown, complex or otherwise does not match …
4Microstrip antenna — In telecommunication, there are several types of microstrip antennas (also known as printed antennas) the most common of which is the microstrip patch antenna or patch antenna. A patch antenna is a narrowband, wide beam antenna fabricated by… …
5Television antenna — A Winegard HD 7084P 68 element VHF/UHF aerial antenna A television antenna, or TV aerial, is an antenna specifically designed for the reception of over the air broadcast television signals, which are transmitted at frequencies from about 41 to… …
6Image antenna — In telecommunication, an image antenna is a theoretical mirror image of an antenna, an antenna element considered to extend below the ground plane as the actual antenna is above the ground plane. Note 1: The image antenna is helpful in… …
7Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
8Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with …
9Driven element — Active element redirects here. For the devices used in electronic circuits, see active component. A Yagi antenna with one driven element (A) called a folded dipole, and 5 parasitic elements (B and C). A feed line leading to the receiver (not… …
