Wideband Balanced Antipodal Vivaldi Antenna with Enhanced Radiation Parameters
نویسندگان
چکیده
A novel balanced antipodal Vivaldi antenna (BAVA) with high gain and enhanced radiation parameters is proposed in this paper. The outer edges of the flare are modified by a binomial curve to broaden the impedance bandwidth. A modified metal director is adopted to improve the antenna gain and beam-tilting. The measured results show that the proposed BAVA achieves a bandwidth from 2 to more than 40GHz with peak gain > 0 dBi and > 1 dBi over the 8–40GHz range. The squinting beam of E-plane is less than 5◦ from 4 to 40GHz and less than 3◦ from 22 to 40GHz.

A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...
