Abstract
This paper proposes a dual-mode CPW-fed antenna array composed of stub-loaded slot antennas, which can be applied in the fifth generation (5G) millimeter-wave (mm-wave) applications. Each slot antenna element is fed by the coplanar waveguide (CPW). By loading a stub on a half-wavelength slot antenna, two different resonant modes can be obtained. In addition, a 6-element antenna array is presented. The distance between any two adjacent antenna elements is about one wavelength at 28GHz. The simulated results show that the designed mm-wave antenna array can realize a 29.3% impedance bandwidth with a return loss larger than 10dB and an inter-element isolation higher than 18dB from 24GHz to 32GHz. Moreover, the realized gains of the 6-element antenna array are greater than 11.5dB over the operating frequency band with maximum value of 13.9dB at 28GHz.
