Exponentially Tapered Slot Fig. 1 shows the antenna model. The antenna is 0.64 λ0 × 1.6 λ0 and 14.7 λ0 × 35.5 λ0 at 2.5 GHz and 57 GHz, respectively, where λ0 is the free space wavelength. The time domain solver (CST Microwave Studio) is used for all simulations as it lends itself better to electrically large and UWB structures.

Crossed exponentially tapered slot antenna. Planar elliptical dipole for UWB. CPW-fed annular monopole antenna. The crossed exponentially tapered slot antenna may find application in the FCC (and ETSI) defined ultra-wideband (UWB) radio band of 3.1 - 10.6 GHz. The antenna combines two crossed exponentially tapered slots with a star-shaped slot to produce a stable radiation pattern.

A Vivaldi antenna or Vivaldi aerial^[1] or tapered slot antenna^[2] 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.

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. From the open space area the energy reaches an exponentially tapered pattern via a symmetrical slot line.

Vivaldi antennas can be made for linear polarized waves or – using two devices arranged in orthogonal direction – for transmitting / receiving both polarization orientations.

If fed with 90-degree phase-shifted signals, orthogonal devices can transmit/receive circular-oriented electromagnetic waves.

Vivaldi antennas are useful for any frequency, as all antennas are scalable in size for use at any frequency. Printed circuit technology makes this type antenna cost effective at microwave frequencies exceeding 1 GHz.

Advantages of Vivaldi antennas are their broadband characteristics (suitable for ultra-wideband signals ^[3]), their easy manufacturing process using common methods for PCB production, and their easy impedance matching to the feeding line using microstrip line modeling methods.

The MWEE collection of EM simulation benchmarks includes a Vivaldi antenna.^{[4][5][6][7][8][9]}
