Abstract

In Fibre-Wireless (Fi-Wi) links, conversion devices between wireless microwave/ millimetre-wave and lightwave signals are required. In this paper, we propose a wireless millimetre-wave-lightwave signal converter using an electro-optic (EO) modulator with Quasi-Phase-Matching (QPM) array of orthogonal-gap-embedded patch-antennas on a low-k dielectric material. Wireless millimetre-wave signals can be received and converted directly to lightwave signals using the proposed device. It can be operated with no external power supply and extremely-low millimetre-wave losses. The orthogonal-gap-embedded patch-antennas can be used for receiving dual-linearized or circular polarizations of wireless millimetre-wave signals. The QPM array structure can be adopted for enhancing modulation efficiency by transit-time effects consideration. Structure, analysis, and experimental of the proposed device are discussed for 40GHz operational millimetre-wave bands.

基于低k介电材料的正交隙嵌入贴片天线准相位匹配阵列毫米波电光调制器

在光纤无线(Fi-Wi)链路中，需要无线微波/毫米波和光波信号之间的转换设备。在本文中，我们提出了一种无线毫米波-光波信号转换器，该转换器使用电光(EO)调制器，并在低k介电材料上嵌入准相位匹配(QPM)正交缝隙贴片天线阵列。无线毫米波信号可以被接收并使用所提议的装置直接转换为光波信号。它可以在没有外部电源的情况下运行，毫米波损耗极低。正交缝隙嵌入贴片天线可用于接收双线性或圆极化的无线毫米波信号。考虑到传输时间效应，可以采用QPM阵列结构来提高调制效率。讨论了该器件在40GHz毫米波工作频段的结构、分析和实验。
