摘要： According to one embodiment, an antenna apparatus includes an antenna, a duplexer, a reception circuit, a phase controller, a combining unit, a thermally insulating container and a cooling unit. A reception circuit configured to separate a frequency of a signal received by the antenna into a plurality of reception pathways via BPFs (Band Pass Filters) corresponding to the number of transmittable frequencies, extract the reception signals, amplify with low noise the extracted reception signals by an LNA (Low Noise Filter) for the separated reception pathways, select a reception pathway corresponding to the transmission frequency from the separated reception pathways, and output the reception signal amplified with low noise to the selected reception pathway.
