FIELD: electric engineering. ^ SUBSTANCE: invention is related to the field of electric engineering, in particular to antenna design. Combined wideband antenna may be used in transceiver systems of short waves or ultrashort waves bands. Combined wideband antenna comprises log-periodic antenna, cable for supply of log-periodic antenna, wideband dipole with matching transformer, which is installed behind reflector, and also mast, top of which is located higher than log-periodic antenna, besides mast is mechanically connected to wideband dipole of log-periodic antenna, conductors of which are fixed to reflector ends and upper part of mast, from where they turn in direction to ends of shortest directors of log-periodic antenna, and then towards to each other and are connected to each other via active resistance. Wideband dipole is installed above log-periodic antenna practically in projection of log-periodic antenna curtain area. ^ EFFECT: antenna structure is small-sized, light in weight, is detachable, convenient in transportation, has low windage, with sufficient rigidity, has high electrotechnical characteristics. ^ 9 cl, 2 dwg |
