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.
