The characteristics of the Vivaldi antenna were understood through extensive simulations performed in Ansoft HFSS after which the Vivaldi antenna was built and tested at the RSL. The gain and the S11 of the single element were found to be quite poor. Subsequently, a 12-element array was built. A metal plate was fixed to the back of the

A half-wave dipole antenna has a power gain of 1.64 (or 2.15 dB) over an isotropic source. Antenna gain relative to a dipole antenna can be expressed in decibels as dBd. Thus, an antenna with a gain of 3 dBd would have a gain of 5.15 dBi (3 dB 2.15 dB) 10log (1.64) 2.15 dBi10 Actual Antenna Lengths

if an antenna has a gain of 3 dBd it also has a gain of 5.2 dBi. Note that when a single number is stated for the gain of an antenna, it is assumed that this is the maximum gain (the gain in the direction of the maximum radiation). It is important to state that an antenna with gain do

of the radiation also varies depending on the antenna design. Similar to Gain, the directivity of an antenna is expressed in dB and it can be also expressed in dBi if it is defined relative to an isotropic radiator. 2.4 Antenna gain Antenna gain is one of the important parameters used to describe antenna performance.

Antonio Lucio Vivaldi Antonio Lucio Vivaldi was buried on July 28th 1741 in a pauper's grave in Vienna. Although he had been a famous musician, receiving commissions from courts throughout Europe, and his music had been transcribed and copied far and wide, he died a poor man in a foreign country. Both Vivaldi and his music were soon forgotten.

While most of Vivaldi's instrumental music is particularly popular and well known, his ope-ra compositions (there are 45 of them!) are ra-rely performed. Vivaldi's FARNACE received its world premiere during the Carnival Season in February 1727 at the Teatro di Sant'Angelo in Venice. FARN-ACE became a kind of touchstone for Vivaldi's

Vivaldi - Gloria in D RV 589 Antonio Lucio Vivaldi composed this Gloria in Venice, probably in 1715, for the choir of the Ospedale della Pietà.

A small GND plane makes the antenna omni-directional, which gives more freedom to the placement of the antenna, but has smaller gain in all directions. Antenna size influences the gain as well.

An Antenna Analyzer is more then a SWR meter. An Antenna Analyzer can help maximize your antenna system's performance. An Antenna Analyzer can help you find problems in your antenna system. SWR is an indicator of how well the feed line is matched to the antenna. If the Impedance is 50 ohms but, the SWR is not 1.0:1.
