Abstract: 
A compact ultra-wideband crossed-dipole antenna is proposed for 2G/3G/4G/IMT/5G customer premise equipment (CPE) applications. The arms of the crossed-dipole antenna are formed by step-shaped patches, and a wideband operation can be realized by properly selecting the order of the step-shaped patches; its bandwidth can be further enhanced by extending the end of crossed dipole downward. Each dipole is excited by a microstrip stub that is directly connected to a coaxial cable. Furthermore, a slotted rectangular parasitic patch is added beneath the crossed dipoles to further support a 5G sub-6-GHz band without additional space cost. The test results for the prototype of the proposed antenna show that the crossed-dipole antenna has a bandwidth of 147.3% (0.77–5.07 GHz) for return loss lower than 10 dB and an isolation higher than 20 dB between two ports.
