摘要： An antenna apparatus includes a slit provided on an antenna element between first and second feed ports; and a series resonant circuit provided at a location along the slit, with a distance from an opening of the slit. When the antenna apparatus operates at a first isolation frequency identical to a resonance frequency of the series resonant circuit, the series resonant circuit is short-circuited, and only a section of the slit from its opening to the series resonant circuit resonates, thus providing isolation between the feed ports at the first isolation frequency. When the antenna apparatus operates at a second isolation frequency lower than the first isolation frequency, the series resonant circuit is open, and the entire slit resonates, thus providing isolation between the feed ports at the second isolation frequency.

摘要： A transmitting signal from a signal generator is divided in seven transmitting signals in a divider, and the phase and the amplitude of each of divided transmitting signals are changed in a phase shifter circuit and an attenuator circuit. The respective transmitting signals from the attenuator circuit are radiated from scatterer antennas. A receiver receives a multiple wave of radiated radio waves by using a receiving antenna. A computer substantially simultaneously starts operations of a D/A converter, the signal generator, and the receiver by using a trigger generator circuit.
