摘要

本文提出了一种将未来毫米波系统的振荡器电路和天线统一起来的方法。在这里,存在于振荡器电路中晶体管两侧的无源电路被天线取代。该原型由两个天线组成,以线性阵列排列,晶体管放置在它们之间的间隔。报告了一般建模程序,然后在5 GHz频率上进行了概念验证演示。从测量结果来看,频率调谐可达70mhz,约为5ghz;从模拟结果来看,在波束转向角度相对于舷侧为- 20°时,最大辐射可被观测到。为了减少初始分析和优化的时间,本文建立了相同的传输线模型

A Novel Approach for Modelling Oscillator Circuit with Antennas
This paper presents an approach to unify oscillator circuit and antenna for future mm wave systems. Here, the passive circuitry present on both sides of transistor in an oscillator circuit are replaced by antennas. The prototype consists of two antennas arranged in a linear array with transistor placed in the spacing between them. General modelling procedure is reported followed by proof of concept demonstration at frequency of 5 GHz. Frequency tuning up to 70 MHz is also achieved around 5 GHz from measurements and maximum radiation is observed at beam steered angle of −20° with respect to broadside, from simulation. Transmission line model of the same is developed to reduce the time for initial analysis and optimization, and presented here
