    A dual-band endfire antenna phased array suitable for 5G NR mmWave bands applications is presented in this paper. The antenna introduces a novel radiating aperture array analogy based on open-end substrate integrated waveguide (SIW) technology to achieve wide dual-band operation and vertical polarization radiation. The simulated -10 dB impedance bandwidth achieves 17.4 % (25.2-30 GHz) lower band and 12.4 % (36.4-41.2 GHz) higher band covering mmWave 5G NR bands; n257, n260, and n261 with isolation levels higher than 15 dB over the operating bands. The peak realized gain is 8.8 dBi and 11.8 dBi in the lower and higher bands, respectively. The mmWave array delivers a scanning angle of ±50° and ±33° for a realized endfire gain higher than 6.5 dBi and 8.5 dBi at 28 GHz and 39 GHz, respectively.
