Advantages of Vivaldi antennas are their broadband. Chen, Transfer functions measurement for UWB antenna, in IEEE APS International Symposium, vol. Printed circuit technology makes this type antenna cost effective at microwave frequencies exceeding 1 GHz. Conventional Vivaldi antenna has the advantages of ultra wideband, but its backward radiation is too large and the the gain of the main radiation direct is low. Baum, Extending the definitions of antenna gain and radiation pattern into the time domain, Sensor and Simulation Notes, Note 350, 1992. This paper will discuss the design of a vivaldi microstrip antenna which has a wide bandwidth with directional radiation pattern works on 3.1 to 10.7 GHz and. Davis, Designing antennas for UWB systems, in Microwave & RF, 2003, pp. Wiesbeck, Transient responses of a Vivaldi antenna and a logarithmic periodic dipole array for ultra wideband communication, in IEEE APS International Symposium, vol. Gibson, The Vivaldi aerial, in Proceedings of the 9th EuMC, Brighton, UK, September 1979, pp. A wide beam Vivaldi antenna based on elliptical slot structure is proposed, and the size is 150 mm×150 mm×1.6 mm. In this paper, the traditional radiation structure of Vivaldi antenna is improved. However, as a transmitting antenna, the Vivaldi antenna beam width is insufficient. Wu, Wide-slot antenna for UWB applications, in IEEE AP-S International Symposium, vol. Vivaldi antenna has superior radiation performance and simple process, which can be used for common radar ranging. Fullerton, The diamond dipole: a Gaussian impulse antenna, in IEEEAP-S International Symposium, vol. The designed antenna is an antipodal Vivaldi antenna with 5.0-8.0-dB gain and half-power beamwidths of 79.0° and 76.0° in its E- and H-planes, respectively.
