Claim:
1. An antenna module for wireless communication comprising: an antenna element comprising a first resonance frequency and a second resonance frequency; a first port configured to receive or provide a first radio frequency signal with a first frequency range; a second port configured to receive or provide a second radio frequency signal with a second frequency range, wherein the first frequency range and the second frequency range are different from each other, wherein the first resonance frequency is located in the first frequency range and the second resonance frequency is located in the second frequency range, wherein the antenna element is configured to transmit or receive the first radio frequency signal and the second radio frequency signal simultaneously; and further comprising a coupler element connected to the first port and arranged in the proximity of the antenna element to couple the coupler element capacitively or inductively to the antenna element for transmitting or receiving the first radio frequency signal through the antenna element; wherein the coupler element is connected to the first port through a matching element configured to adapt an impedance of the first signal path from the first port to the coupler element to the first resonance frequency of the antenna element to obtain a reflection coefficient of less than −6 decibels (dB) for the first radio frequency signal.
