Tri-band antenna array with defected ground structure for mm-wave 5G applications

• This work presents a tri-band planar antenna array envisioned for assimilation into future 5G mm-wave wireless communication applications. The proposed assembly comprises of four antenna elements excited by a 1×4 T-junction power divider/Combiner and Defected Ground Structure (DGS). The antenna array presented in this work is modeled on Rogers RT/Duroid 5880 substrate with an overall size of 14 × 60 × 0.787 mm3. The frequency bands covered by the antenna system are centered at 29, 37.37 and 41 GHz with 10 dB bandwidths of 1.25, 1.3 and 2.14 GHz respectively. The peak gain attained by the antenna array is 11.8 dB. The proposed design with compact, simple and low profile assembly along with good radiation characteristics ascertains to be appropriate for mobile terminals and handheld wireless devices.
