Dipole Antennas and Wire Antennas

 

Dipole antennas or wire antennas are among the simplest and most common type of antennas. They typical configuration for a dipole antenna is a straight, center-fed, one-half wavelength antenna. Often, theya re used in conjunction with a dielectric coating to enhance radiation characteristics. Many variations of wire antennas or dipoles are available. These include straight wire or simple dipole; folded dipole; coil; magnetic dipole or loop (circular, square, ellipse, rhombus, fan, eggbeater, rabbit ear, etc.); inverted L, V, or F antennas; turnstiles or crossed dipoles, vertically-polarized dipoles, diversity dipoles, helical (volute and quadrifilar helix antennas) and sleeve dipoles. Other types of dipole antennas and wire antennas are also available.

Products & Services
Horn Antennas
Horn antennas are used for the transmission and reception of microwave signals. They are usually fed by waveguides.
Antenna Design Software
Antenna design software is used for the design and electromagnetic analysis of all types of antenna systems, including planar and microstrip antennas, hollow waveguide and horn antennas, and helical antennas.
Radomes
Radomes are weatherproof enclosures to protect an antenna from the elements.  Radomes are more typically used on satellite or microwave antennas, but can be used with any antenna.
Chip Antennas
Chip antennas are semiconductor ICs used to collect or radiate electromagnetic waves.
