Slot antennas are low profile antennas used in places where antenna installation space is limited. These antennas operate at ultra-high frequency (UHF) and are widely used as radar antennas and sector antennas used in cell-phone base stations. Vivaldi is a type pf slot antenna. It is a directive antenna used in ultra-wide band (UWB) applications due to the simple structure and small size. Antipodal Vivaldi comes under the group of end fire tapered slot antennas. This type of antennas is expected to provide medium gain with less side lobes and wide bandwidth.

Featured Examples

Design and Analyze Parabolic-Reflector-Backed Wideband Eggcrate Array

Create an eggcrate array of vivaldiOffsetCavity antenna elements backed by a parabolic reflector. The Vivaldi antenna is widely used in radar and electronic countermeasures because of its simple structure and wide operating bandwidth. The eggcrate array consists of Vivaldi antenna elements oriented in a grid. The eggcrate array in Antenna Toolbox™ is a fully metallic array, which is capable of handling a high average power. Vivaldi phased arrays are used for a wide range of applications at various frequencies and bandwidths. The eggcrate array of vivaldi antenna elements provides a wide bandwidth. You can back the array with any Antenna Toolbox backing structure. In this example, you analyze the Vivaldi element, eggcrate array, and eggcrate array backed with a parabolic reflector over 5G frequency bands.
