A Compact Slot-Based Antenna with Pattern Diversity for FTTR Applications
Zetao Huang, Zhan Wang, Xin Yu Zhou, Yuandan Dong · 2025
In this paper, a compact pattern diversity antenna is proposed for application in Fiber-to-the-Room (FTTR). Derived from a conventional dual-port slot antenna, a new antenna with compact configuration and efficient radiation is presented, featuring a compact aperture of 0.63 λ0× 0.36 λ0(where λ0is the wavelength at 5.5 GHz) and radiation efficiency over 96%. Notably, the proposed design achieves pattern diversity through the modulation of phase differences between the feeding ports, enabling continuous beam scanning. The designed pattern diversities antenna has the merits of a compact dimension, simple structure, flexible beam-switching ability, and excellent radiation capacity, making it appropriate for intelligent communication applications.
