Полезная модель относится к антеннам приема цифрового телевизионного сигнала. Устройство выполнено в виде антенной конструкции, содержащей антенную структуру, печатную плату, схему антенного усилителя, схему обхода сигнала, корпус антенны, и характеризуется тем, что в корпусе антенны к антенной структуре непосредственно подключена печатная плата, на которой размещены схема антенного усилителя и непосредственно подключенная к ней схема обхода сигнала, таким образом, что антенная конструкция совмещает в себе и активную, и пассивную антенну, в зависимости от подачи на нее напряжения, так что при подаче питающего напряжения на печатную плату устройство переходит в активный режим работы, при котором принятый антенной структурой телевизионный сигнал поступает в схему усилителя, а при отключении питающего напряжения с печатной платы устройство переходит в пассивный режим, при котором принимаемый антенной структурой телевизионный сигнал поступает в схему обхода сигнала. Техническим результатом, обеспечиваемым приведенной совокупностью признаков, является возможность использования антенны в пассивном режиме (без подачи на схему антенного усилителя питающего напряжения), при котором повышается стабильность и уровень качества принимаемого цифрового телевизионного сигнала, поступающего на вход цифрового телевизионного приемника, и в активном режиме (с подачей питания на схему антенного усилителя), при котором увеличивается усиление принимаемого антенной цифрового телевизионного сигнала, повышается дальность приема и компенсируются потери в высокочастотных трактах передачи принимаемого цифрового телевизионного сигнала от антенны к цифровому телевизионному приемнику, в результате чего такая антенна благодаря поддержке двух режимов работы может улучшать те или иные параметры качества принимаемого цифрового телевизионного сигнала в зависимости от условий приема, что в целом позволяет добиться приемлемого для конкретной ситуации уровня приема сигнала. 1 ил.

Processes and systems for radiating electromagnetic energy from an open-ended coaxial cavity are described herein. An antenna assembly includes an open-ended coaxial radiator. The coaxial assembly includes an inner electrically conducting surface and an outer conductive surface spaced apart from and opposing the inner electrically surface. More than one radially aligned electromagnetic coupling modules are positioned at least partially within the coaxial waveguide along different rotation angles. Each of the different electromagnetic coupling modules samples a local electric field, amplifies the sampled field, and alters a phase of at least one of the amplified fields. The amplified, phase-adjusted coaxial fields are radiated from an open end of the coaxial cavity. Although described for transmission mode, the structure can be operated in receive mode by similarly detecting radiated electric fields, amplifying and applying a phase offset, and radiating the amplified, phase offset fields into an open-ended coaxial cavity.
