RADIO FREQUENCY MODULE AND WIRELESS DEVICE

The present invention provides a radio frequency module including: an interposer; a plurality of antenna element groups that include first electrodes and a second electrode and are configured such that the first electrodes are aligned in line shapes in at least a first direction on a first surface of the interposer; and meta material portions that are provided at the interposer and affect electromagnetic properties of the plurality of antenna elements. The meta material portions include electromagnetic band gap structures provided by forming predetermined geometric patterns near both sides of the first electrodes along at least the first direction. The radio frequency module can thus have a reduced size and a broad band/a high gain.
