A loop‐type ground radiation antenna is proposed for a discontinuous square ring‐shaped ground plane. The antenna shows strong coupling with the ground mode if it is located at the maximum current density location. The location of the antenna has been evaluated using characteristic mode analysis of the currents on the ground plane. The size of the loop‐type ground radiation antenna is 10 × 4.5 mm and it is fabricated on a square ring‐shaped ground plane of size 50 × 50 mm having a gap of 2 mm. The design is intended for mobile device applications operating at 2.45 GHz.
