Digital video broadcasting terrestrial receiving device for mobile device, has high-frequency push-pull amplifier arranged in central region between foils of butterfly-antenna, where terminal of amplifier is connected with ground potential

摘要

The device has two conducting surfaces (3a, 3b), which form the foils of a butterfly-antenna. A feed-in point of a high frequency push-pull amplifier (6) is arranged in a central region between the foils of the butterfly-antenna such that the foils are connected directly with the inputs of the amplifier. The amplifier amplifies the signals received by the antenna, and a terminal of the amplifier is connected with a ground potential.
