PROBLEM TO BE SOLVED: To provide radio communication equipment which can operate in different frequency bands, and which has a small volume.SOLUTION: Radio communication equipment includes: a circuit board; and a metallic area and a filter disposed on the circuit board. A slot is disposed in the metallic area, and the filter is connected to the side of the slot, and the slot is divided into a first slot part and a second slot part. When the filter is in a communication state, the slot generates a first resonant mode, and transmits and receives a radio signal having a first center frequency, and when the filter is in a short-circuit state, the first slot part generates a second resonant mode, and transmits and receives a radio signal having a second center frequency. |
