提出了一种适用于60 GHz频段多Gb/S数据传输的紧凑型无线接入系统。接入点中的大型阵列天线产生准平面波，并形成与天线大小成正比的稳定通信区。在该紧凑距离通信系统中，基于Friis传输方程的链路预算不再适用。高达10米的信号覆盖范围仍在大型阵列天线的菲涅尔区内。覆盖范围内任何地方的移动用户都会收到几乎恒定的场强，没有多径干扰。为了验证其可行性，设计并制作了不同尺寸的圆极化波导缝隙阵列。在对传统天线射频性能进行评估的基础上，通过误码率和信噪比测试对千兆比特紧凑型无线接入系统原型进行评估。
A novel compact-range wireless access system is proposed for multi-Gb/s data transfer in the 60-GHz band. Large-array antennas in the access point generate a quasi-plane wave and form a stable communication zone proportional to the antenna size. The link budget based upon the Friis transmission equation is not applicable as ever in this compact-range communication system. The signal coverage up to 10 m still falls within the Fresnel region of the large-array antenna. Mobile users everywhere within the coverage receive almost constant field strength free of multipath interference. To demonstrate the viability, circularly polarized waveguide slot arrays of various sizes are designed and fabricated. After the evaluation of conventional antenna radio frequency (RF) performance, bit-error rate (BER) and signal-to-noise ratio (SNR) measurements are conducted to evaluate the prototype of a compact-range Gigabit wireless access system.
