Vivaldi antenna arrays for SKA
IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002We present several broad band arrays of tapered slot antennas for use in a new generation phased array telescope. In specific, a four element linearly polarized 3-12 GHz array, a 3 element 0.8-2.5 GHz coupled array and a four element dual polarized 0.8-2.5 GHz array are discussed. Integration with LNAs and coupling between elements is examined.

Characteristics of pulsed Vivaldi antenna
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004Experimental and theoretical results of investigation of the Vivaldi antenna in the pulsed mode of operation are presented. Antenna power directive gain and efficiency of feeder system are calculated as a function of Gaussian pulse duration exciting the system. Experimental results on registration of received pulse time dependences in the communication

Improved design of the Vivaldi antenna
IEE Proceedings H Microwaves, Antennas and Propagation, 1988The Vivaldi antenna and its feeding transition is investigated. A tapered transition from microstrip to symmetric double sided slot line, fabricated on a low dielectric constant substrate, exhibits a very wide operating frequency range, with no need for a shorting hole.

A tuneable Antipodal Vivaldi antenna for UWB application
10th International Multi-Conferences on Systems, Signals & Devices 2013 (SSD13), 2013This paper presents a tuneable Antipodal Vivaldi antenna by employing symmetrically corrugated ripples on the frontier of the antenna in order to improve the radiation performance. This configuration is able to produce good input match, low dispersion, high gain, small sidelobe level and constant radiation pattern of 10±1.5 dB over the frequency band.

Antipodal Vivaldi antenna for phased array antenna applications
Proceedings of 2012 5th Global Symposium on Millimeter-Waves, 2012This paper describes an antipodal Vivaldi antenna on Rogers4350B substrate at the operating frequency band of 6∼18GHz. Both simulation and measurement results show superior performance with high gain of 6–10dB and symmetrical H-plane characteristics. In addition, a 1×8 H-plane phased array with alterable spacing between adjacent elements is constructed

Microstrip antenna has received a lot of attentions due to its advantages such as low profile, light weight and easily reproducible. However, the inherent characteristic of microstrip antenna is narrow band. Many techniques had been developed to make the microstrip antenna broadband such as shaping the physical shape of the radiating element or using ...
