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.

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： An antenna apparatus includes antenna elements, each made of a conductive plate. The antenna elements are provided along a reference axis passing through first and second positions of the antenna apparatus, and close to a section between the first and second positions. Each of the antenna elements has first and second portions along a circumference of the antenna element, the first portion is close to the reference axis and electromagnetically coupled to the other antenna element, and the second portion is remote from the reference axis. The first portions of the respective antenna elements are shaped so that the antenna elements are the closest to each other near the first position, and a distance between the antenna elements gradually increases from the first position to the second position. The antenna apparatus has feed points provided on the antenna elements, respectively, and near the first position.
