Abstract :
High directivity antennas are often used in communication systems to meet specific coverage requirements. This paper presents a unidirectional, high gain UWB antenna. A reference UWB antenna is considered and a metallic cavity is built around it, this arrangement along with a stacked parasitic patch shows a maximum increase of 8.5 dB in the gain of the UWB antenna. A maximum increase of 8.43 dB in the gain is seen for the UWB antenna having band rejection feature.
