Abstract
ANTENA ZA DEKAMETARSKE TALASE, koja ima najmanje jedan zastor postavljen vertikalno sa dipolima (d2, d3, d5-d16) rasporedjenim u grupama na različitim nivoima. Pravougaeni oblik zastora sa dipolima kod poznatih antena je napušten u korist jednog oblika koji je više sužen u gornjem delu zastora, zahvaljujući tome što je jedan broj dipola smanjen u gornjem delu (d2-d3) u odnosu na broj u grupama donjeg dela (d5-d8; d9-d12; d13-d16); reflektor (Rb) pridružen zastoru ima odgovarajuću površinu manje širine u gornjem delu u odnosu na donji deo. Performanse su samo malo izmenjene, a konstrukcija je znatno lakša. Primenjuje se naročito kod obrtnih antena.DECAMETER WAVES ANTENNA, which has at least one curtain mounted vertically with dipoles (d2, d3, d5-d16) arranged in groups at different levels. The rectangular shape of the dipole curtain at known antennas has been abandoned in favor of a single shape that is more tapered in the upper part of the curtain, due to the fact that one number of dipoles is reduced in the upper part (d2-d3) relative to the number in the lower part groups (d5- d8; d9-d12; d13-d16); the reflector (Rb) associated with the curtain has a corresponding surface of less width in the upper part relative to the lower part. The performance is only slightly altered, and the construction is much lighter. It is especially applicable for rotary antennas.
