FIELD: radio engineering; antenna engineering. SUBSTANCE: antenna for reception of signals in two considerably separated decimetric and metric wave bands has frame 1, conductor 2 connected to the midpoint of frame 1, and duplexer 3 having generally a switch and a balance converter. Two embodiments of the antenna are described: one with a common feeder for two subbands and the other with two feeders. Results of experimental investigations are presented. EFFECT: reduced dimensions of antenna which allows its use indoor or as a built-in antenna for portable TV sets. 2 cl, 6 dwg |
