A Multiple Input Multiple Output (MIMO) antenna apparatus is provided. The apparatus includes antenna devices that operate in respective resonant frequency bands. The apparatus also includes a main board comprising a device region and a ground region. The antenna devices are disposed on the device region. The ground plate is disposed on the ground region for grounding the antenna devices. The apparatus also includes at least one isolation device having a negatively charged line that protrudes from the ground plate and extends between the antenna devices on the device region, and a positively charged line that extends around the negatively charged line and connects the antenna devices to each other. The isolation device induces an electromagnetic wave that is generated by the antenna devices between the negative and positively charged lines to isolate the antenna devices from each other.

MIMO antenna apparatus

An antenna apparatus allows for internal impedance matching by employing an internal matching device therein. The antenna apparatus includes a board body formed of a dielectric material and having a flat structure. The antenna apparatus also includes an antenna device disposed on an upper surface of the board body, and the internal matching device disposed on a lower surface of the board body. The antenna device extends from a feed point and has a first impedance. The internal matching device is connected to the antenna device and has a second impedance used for matching the first impedance with a reference impedance. The antenna device and the internal matching device resonate at the reference impedance in a specific frequency band when a voltage is supplied through the feed point.
