A miniaturised multiband directional dipole antenna for mobile communication applications is proposed. The proposed antenna consists of electromagnetically coupled two‐dipoles with a folded reflector and inverted L‐shape stubs on the edge of the folded reflector. The stubs are used to obtain a reduction of the antenna size. The occupied volume of the proposed antenna is 0.34 λ 0 × 0.29 λ 0 × 0.10 λ 0 . ( λ 0 is the wavelength at 900 MHz) To provide multiband characteristics, the radiator designed electromagnetically coupled two‐dipoles with dual resonance frequencies. The performance of the proposed structure successfully covers the frequency bands of 700–1000 MHz and 1700–2700 MHz.
