Improved design of the Vivaldi antenna

IEE Proceedings H Microwaves, Antennas and Propagation, 1988
The 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 design of phased array antenna based on the Vivaldi antenna

2010 2nd International Conference on Industrial and Information Systems, 2010
A new design process of a phased array antenna at 2GHz is presented by the simulation method. First a suitable antenna pattern for the radiator of Vivaldi is selected as a slot antenna with light weight, small volume, low cost and high gain. A kind of the analysis software of high frequency structure simulation CST MWS is optimized for the VSWR and ...

A Reconfigurable Vivaldi Antenna with bandwidth control

2019 15th International Conference on Electronics, Computer and Computation (ICECCO), 2019
This paper proposes a reconfigurable Vivaldi antenna with bandwidth control. The Vivaldi antenna is incorporated with two pairs of circular slot resonator for the purpose of switching. Pin diodes are used to switch ON/OFF the circular slot resonators one pair at a time. The bandwidth of the Vivaldi antenna can be controlled from a wideband (1. 08GHz to

Vivaldi antennas: wideband radar antennas simulation and reality

IET International Conference on Radar Systems 2007, 2007
Multiple applications sharing a single multiple-aperture array is a driver for research into wideband antenna design. Vivaldi antennas are inherently wideband and are known to have good RF characteristics, are inexpensive and easy to manufacture, and have a flat profile enabling construction of compact arrays.

Vivaldi antenna

2008
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 ...

A Broadband Millimeter-Wave Vivaldi Antenna on LTCC

2006
An exponentially-tapered slot antenna on low-temperature co-fired ceramic (LTCC) substrate is presented. It is designed to be used over a broad frequency range in the millimetre-wave band. LTCC technology is used for its low-cost and high-tolerance performances.
