摘要： An antenna apparatus in which a combination of rectangular waveguides 9a and 10a and a combination of rectangular waveguides 9b and 10b are disposed bilateral symmetrically to each other, and a waveguide orthomode transducer 13 is disposed above a waveguide orthomode transducer 8 is provided. Therefore, the profile of the antenna apparatus can be reduced and the stability of installation of the antenna apparatus can be improved without impairing the electric characteristics of the antenna apparatus. Since the antenna apparatus has a bilateral symmetric structure, it excels in weight balance and offers stable performance from the viewpoint of mechanism.

摘要： In a variable power divider including a first 90° phase combiner (30), a second 90° phase combiner (40), and a phase-amplitude adjustment block (50), the phase-amplitude adjustment block (50) includes, correspondingly to two-channel polarized signals, variable phase shifters (51, 52) for adjusting their phase amounts and variable attenuators (55, 56) for adjusting amplitudes (attenuation amounts), and the phase amounts and the amplitudes of the two-channel polarized signals can be adjusted by an antenna control unit (60). Further, there are included a phase shifter (53) and an attenuator (57) provided on two-channel signal lines between an orthomode transducer (20) and a first 90° phase combiner (30) and for equalizing the amplitudes and phases of the two-channel polarized signals. By this, an antenna apparatus can be inexpensively provided which uses a reflector antenna (10) to perform transmission/reception of a signal to/from a satellite at high accuracy, and is miniaturized to be suitable for mounting on an aircraft or the like.

摘要： In a moving body satellite communication apparatus for performing communication with a satellite by an antenna with a radome mounted on a moving body such as an aircraft, loss due to transmission through the radome, and distortion of polarization characteristics are compensated in the inside of the antenna. Variable phase shifters 9a and 9b and variable attenuators 19a and 19b, and variable phase shifters 10a and 10b and variable attenuators 20a and 20b are respectively controlled as one body in each channel, and the whole power EIRP radiated from the antenna is also optimally controlled by a common variable attenuator 21 inserted independently from the variable attenuators 19a and 19b, and therefore, radome correction and EIRP control can be simultaneously realized by a relatively simple circuit.
摘要翻译：在通过具有安装在诸如飞机的移动体上的天线罩的天线进行与卫星的通信的移动体卫星通信装置中，在天线的内部补偿由于通过天线罩的传输引起的损耗和极化特性的失真。可变移相器9a和9b以及可变衰减器19a和19b以及可变移相器10a和10b以及可变衰减器20a和20b分别被控制在每个通道中的一个主体，并且整个功率EIRP辐射也可以通过独立于可变衰减器19a和19b插入的公共可变衰减器21来最佳地控制天线，因此可以通过相对简单的电路同时实现天线罩校正和EIRP控制。
