摘要： A controller of a MIMO antenna apparatus calculates a current transmission capacity based on signal levels detected by a signal level detector circuit. The controller calculates an estimated transmission capacity assuming that at least one of antenna elements currently connected to a MIMO modulator and demodulator circuit is changed to a further antenna element not connected to the MIMO modulator and demodulator circuit, based on the detected signal levels and degrees of electromagnetic coupling stored in a degree-of-coupling memory. The controller controls a switch circuit to connect the further antenna element to the MIMO modulator and demodulator circuit when the current transmission capacity becomes lower than the estimated transmission capacity.

摘要： An array antenna apparatus includes a first feeding element having a first feed point, a second feeding element having a second feed point, and a first parasitic element electrically connected to the respective first and second feeding elements. In a first frequency band, respective resonances in the feeding elements occur independent of each other, by eliminating electromagnetic mutual coupling between the feeding elements, and exciting the first feeding element through the first feed point as well as exciting the second feeding element through the second feed point. In a second frequency band lower than the first frequency band, a loop antenna having a certain electrical length is formed by the first and second feeding elements and the first parasitic element, and a resonance of the loop antenna substantially occurs by exciting the first feeding element through the first feed point.

摘要： A MIMO antenna apparatus includes a plurality of feeding antenna elements, a parasitic element electromagnetically coupled to each feeding antenna element, and a variable impedance load element connected to the parasitic element. A signal level comparator circuit detects received signal levels of received wireless signals and compares the received signal levels with each other, and thus detects the minimum received signal level. A controller controls an impedance value of the variable impedance load element based on the received signal levels detected by the signal level comparator circuit, such that the received signal level of the wireless signal having the minimum received signal level is substantially maximized.
