1. Title of Invention: ULTRAWIDE BAND RRDA WITH A BEVEL-SHAPED PATCH AND A METHOD

OF DEVELOPMENT THEREOF

1. An ultrawideband RRDA with a bevel-shaped patch and the method of development thereof offers a UWB ranging from 2.5 - 16 GHz (measured value) i.e. fractional bandwidth of 142%; wherein the peak gain of 6.2 dBi at 6.3 GHz and radiation efficiency of 90% utmost value at 4.6 GHz is provided by the RRDA.

2. The method of development of ultrawideband RRDA with a bevel-shaped patch comprising steps of a)the isolated RRDRA is designed using alumina ceramic in combination with a rectangular air cavity and vertical asymmetric conducting strips introduced on sidewalls of the RRDRA to stabilize the gain above0dBi across the entire bandwidth.

3. A slot is introduced in the partial ground plane to optimize the impedance bandwidth.
