摘要： When first and second housings are in an open state, first and second switches are electrically opened, and thus, a first antenna element and a ground conductor operate as a first dipole antenna, and a second antenna element and the ground conductor operate as a second dipole antenna with isolation from the first dipole antenna by the slit. When the first and second housings are in the closed state, the first and second switches are electrically closed, and thus, the first antenna element operates as a first inverted F antenna on the ground conductor, and the second antenna element operates as a second inverted F antenna on the ground conductor with isolation from the first inverted F antenna by the slit.

摘要： A computer measures amplitudes and phases respective received signals S60a relative to a transmitting signal when radio waves are radiated solely from each of the scatterer antennas and received by using a calibration receiving antenna, determines a target amplitude based on measured amplitudes, and determines a target phase based on measured phases. Reference attenuation amount control voltages for respective attenuators are set to attenuation amount control voltages for making the measured amplitudes coincidence with an identical target amplitude, and a reference phase shift amount control voltage for each phase shifter is set to phase shift amount control voltages for making the measured phases coincidence with an identical target phase.

摘要： An antenna evaluation apparatus includes receiving antennas to be evaluated, scatterer antennas provided around them, signal generators, delay circuits, dividers, phase-shift circuits, and attenuation circuits. A computer controls the delay circuits to add delay times to radio frequency signals, and controls the phase-shift circuits and attenuation circuits to change phases and amplitudes of the radio frequency signals to produce a first fading. The antenna evaluation apparatus radiates the radio frequency signals from the scatterer antennas, thus creating multipath waves including delay and fading around the receiving antenna.

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.

摘要： An antenna element has a slit including a first portion and a second portion, the first portion extending in a first direction so as to separate first and second feed points from each other, and the second portion extending in a second direction different from the first direction. The slit is configured to resonate at an isolation frequency to produce isolation between the first and second feed points, and configured to form a current path around the slit. A current distribution along the current path generated by exciting through the first feed point is different from a current distribution along the current path generated by exciting through the second feed point, thus providing different radiation characteristics by the different current distributions.
