摘要： PROBLEM TO BE SOLVED: To provide a reflection mirror antenna capable of correctly measuring intercoupling between radiation elements and an excitation coefficient containing the distortion of the surface of the reflection mirror, and reducing deterioration in radiation pattern. SOLUTION: The antenna has a plurality of minute antennas 44 arranged on the backside of the reflection surface 40, for reflecting radio waves of the reflection mirror and receiving radio waves having transmitted the reflection mirror 40.

摘要： PROBLEM TO BE SOLVED: To provide an automatic tracking antenna device capable of automati cally tracking by means of a simple circuit without feedback control. SOLUTION: A pair of tracking antenna elements 1(-1), 1(1) are disposed in a point symmetrical relationship with respect to a reference antenna element 1(0). Signals received by respective antenna elements 1 are frequency-converted to IF signals by a frequency converter 2. The IF signal of the reference antenna element 1(0) is tripled in its frequency by a multiplier 3, mixed with the IF signal of the tracking antenna element 1(1) by a mixer 4(1), and high frequency components of the mixed signal is removed by an LPF 5(1) to produce a local signal by a carrier reproducing circuit 6(1). The local signal is mixed with the IF signal of the antenna elements 1(-1) disposed at the position having a point symmetrical relationship with respect to the reference antenna element 1(0) by a mixer 7(-1), filtered by an LPF 8(-1), and synthesized in phase by a synthesizer 9.
