The Vivaldi antenna is a special type of tapered slot antenna belongs to the family of end-fire travelling wave antennas and consists of a tapered slot etched onto a thin film of metal. The MWEE collection of EM simulation benchmarks includes a Vivaldi antenna. This inexpensive Vivaldi antenna is etched upon a printed circuit board and fed with a soldered-on coaxial cable and SMA connector.Īdvantages of Vivaldi antennas are their broadband characteristics (suitable for ultra-wideband signals ), their easy manufacturing process using common methods for PCB production, and their easy impedance matching to the feeding line using microstrip line modeling methods. Printed circuit technology makes this type antenna cost effective at microwave frequencies exceeding 1 GHz. Vivaldi antennas are useful for any frequency, as all antennas are scalable in size for use at any frequency. If fed with 90-degree phase-shifted signals, orthogonal devices can transmit/receive circular-oriented electromagnetic waves. Vivaldi antennas can be made for linear polarized waves or – using two devices arranged in orthogonal direction – for transmitting / receiving both polarization orientations. From the open space area the energy reaches an exponentially tapered pattern via a symmetrical slot line.Ī one-piece sheet metal vivaldi antenna undergoing testing in an anechoic chamber The feeding line excites an open space via a microstrip line or coaxial cable, and may be terminated with a sector-shaped area or a direct coaxial connection. ![]() Pattern of a Vivaldi antenna, made from double-sided printed circuit board material A Vivaldi antenna or Vivaldi aerial or tapered slot antenna is a co-planar broadband- antenna, which can be made from a solid piece of sheet metal, a printed circuit board, or from a dielectric plate metalized on one or both sides.
