They are not necessarily mem- bers of the Institute. The standards developed within IEEE represent a cons

Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that ther

Furthermore, the view- point expressed at the time a standard is approved and issued is subject to change brought about through developments in the stat

When a document is more than five years old, and has not been reaffirmed, it is reasonable to conclude that its contents, although
9、 still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. S
10、ug- gestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations : Occasionally questions may arise regarding the mean- ing of portions of standards as they relate to specific applications. When the need for inte
11、rpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the con- currence of a balance of interests
12、. For this reason IEEE and the mem- bers of its technical committees are not able to provide an instant re- sponse to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be ad- dres

14、tandard Definitions of Terms for Antennas.) This standard is a major revision of IEEE Std 145-1973 which it supersedes. It is the second revi- sion of the standard since it was first issued in 1969. A substantive change included in this revision is the deprecation of the term directive gain and its
15、replacement by the term directivity. This change brings this standard in line with common usage among antenna engineers and with other international standards, notably those of the International Electrotechnical Commission (IEC). The 1973 revision was notable in that the interrelationship of gain, i
16、mpedance, and polarization upon the performance of antennas was recognized. That point of view has been further developed for this revision. The terms partial gain, partial directivity, partial effective area and partial realized gain (for a given polarization) have been added. The basic terms, gain
17、, impedance and polarization are left as independent fundamental properties of antennas as before. For the previous revision, the terms on polarization and array antennas were expanded. Addi- tional terms have been added for this revision making it even more comprehensive in these areas. The standar
18、d also includes terms reflecting the advances in antenna technology that have trans- pired since 1973. New terms include microstrip antenna, printed circuit antenna, periscope anten- na, active array antenna system, contoured beam antenna, conformal antenna and null-steering antenna. The previous re
19、vision contained several terms which apply to antennas in physical media. In al- most every case it meant that there were two terms with only minor differences in language, one for free space and one for physical media. For this revision, where possible the two terms were com- bined into a single en
20、try. The terms pertaining to antenna patterns have been expanded in this revision. New terms include axial ratio pattern, beam solid angle, co-polar and cross-polar pattern, difference pattern, directional null, far-field pattern, Fresnel zone, mean side lobe level, near-field pattern, null steering
21、, phase pat- tern, polarization pattern, principal half-power beamwidths, radiation pattern cut, radiation sphere, solid beam efficiency and shoulder lobe. In addition to many new terms, an attempt has been made to improve the language of many of the remaining terms. The Antenna Standards Committee
22、recognizes that further improvements can be made, therefore, suggestions for improvement of this standard will be welcome. They should be sent to: Secretary IEEE Standards Board The Institute of Electrical and Electronics Engineers, Inc 345 East 47th Street New York, NY 10017 This revision of IEEE S
