August 2008 [Test & Measurement] Design An X-Band Vivaldi Antenna, Part 2 Vivaldi antennas can provide excellent directional propagation at microwave frequencies. As introduced in Part 1 of this article (July Microwaves & RF), the Vivaldi antenna can be a simple design based on a tapered-slot-antenna (TSA) architecture. This concluding installment in this two-part article will compare measurements of a designed and fabricated X-band antenna with simulations from the Advanced Design System (ADS) software from Agilent ... July 2008 [Communications] Design An X-Band Vivaldi Antenna Antennas are essential to highfrequency communications and electronic systems for radiating or receiving electromagnetic (EM) energy. Although there are many types of antennas, they all operate according to the same basic EM principles. The basic behavior of an antenna can be described by its wave field strength, polarization, and direction of propagation.1 Key requirements in applications such as airborne radar and communications systems... |
