The antenna was developed for the Romotar program, which is an electronic range measuring program. The antenna is physically small, having a maximum height of 2.3 in., a maximum width of 1.152 in.. and a maximum length of 8.09 in. The antenna is inherently matched and has a bandwidth, between 2 to 1 VSWR points, on a 50-ohm transmission line, of 15.6% about a mean frequency of 438 mc. (auth)
