English Abstract

The classical Vivaldi antenna is recognized for its ultra-wideband property, however average gain and low directivity.

To enhance the directivity, a Double slot construction with 120×80×1 mm3 size has been proposed.

A T-junction power divider with a steady amplitude and phase is utilized to provide excitation for the two slots.

The Double slot construction has the ability to create standard-like waves in the E-plane of the antenna.

As an effect, the gain of the double slot Vivaldi antenna is greatly enhanced matched to the classical Vivaldi antenna.

The consequences present that the frequency domain of the antenna is (3 - 10) GHz.

also an elliptical lens has been added to furthermore improve the Gain of the designed antenna to 14.5 dB.
