Abstract: Vivaldi antenna arrays can be designed for operation over 10:1 bandwidths. Simulated results for an infinite array of stripline-fed Vivaldi elements on ε r =6 substrate performs well for ...

This paper describes an antipodal Vivaldi antenna on Rogers4350B substrate at the operating frequency band of 6~18GHz. Both simulation and measurement results show superior performance with high gain ...

Antenna arrays and wideband technologies are at the forefront of modern wireless communication, radar, and electronic warfare systems. Recent advances have focused on optimising beam steering ...

Spatial resolution in the cross-range dimension is accomplished by using a MIMO antenna array made of overall six broadband Vivaldi antennas, two transmit and four receive antennas. A calibration ...

In FIGURE 1, the Vivaldi antennas are shown with blue dots and are placed on the top of the robotic support 2 meters above the ground. The antenna array covers a scanning area with a radius of 2 ...

The antenna array elements consist of two Vivaldi antennas placed orthogonally on the substrate, with each antenna having vertical and horizontal polarization modes. The patent also describes an ...

Another important aspect is the use of four antennas in a phased array configuration. Existing solutions for 300 GHz CMOS transmitters use a single radiating element, which limits the antenna gain ...
