This paper presents a dual-band printed phased array antenna fed by microstrip lines operated in 5G millimeter wave band. The reflection coefficients are less than −10 dB for lower band (25.5GHz to 28.5 GHz) and upper band (38.5 GHz to 42.5 GHz) band, respectively and the port isolation is better than 12.8 dB. The proposed design is integrated with parasitic elements, shorting pins and copper frame. The dual-band response is achieved by introducing the I-shaped slot from each patch antenna in the array. The simulated directivity of the array antenna is 14.6 dBi and 14.3 dBi at 27GHz and 39GHz, respectively. The proposed phased array is a suitable candidate for 5G millimeter wave mobile communications due to its merits of broadband, good radiation pattern, low profile, and etc. |
