Abstract
In this paper, a dual-band endfire antenna is proposed for promising 5G NR mmWave frequency (FR2) bands applications. The antenna design introduces a novel radiating aperture array analogy based on open-end substrate integrated waveguide (SIW) feeding technology to achieve vertically polarized dual-band operation. The simulated -10 dB impedance bandwidth achieves 11.5 % (26.3-29.5 GHz) lower band and 9.6 % (36.8-40.5 GHz) higher band. The peak realized gain is 8.78 dBi and 11.5 dBi in the lower and higher bands, respectively. The mmWave array delivers a scanning angle of ± 40° and ± 32° for a realized endfire gain higher than 5.5 dBi and 8.2 dBi at 28 GHz and 39 GHz, respectively.
