介绍了一种60ghz开关波束片对片天线阵列。该阵列由四个带侧孔的中心馈电圆形贴片单元组成，以2x2网格排列形成平面阵列。该阵列设计适合于典型的多核芯片，用于可重构的片间无线通信。通过改变方位面上元间相移来切换阵列主波束。通过全波仿真对主波束的切换进行了分析和验证。所提出的设计是对先前设计的双元天线阵列的改进。采用考虑极化分量的弗里斯传输方程对片间无线链路进行建模。为了验证该模型，在一对相距10mm的双元阵列之间进行了透射系数测量。给出了双元阵列的模拟和实测辐射图，用于计算透射系数的Friis方程。对阵列对进行了全波仿真。由Friis模型得到的计算结果与实测和全波模拟结果吻合较好。Friis模型用于计算信号电平和干扰电平。
A 60 GHz switched beam chip-to-chip antenna array is introduced. The array consists of four center fed circular patch elements with side vias in a 2x2 grid arrangement forming a planar array. The array is designed to fit on a typical multicore chip for reconfigurable interchip wireless communication. The array main beam is switched by changing the interelement phase shifts in the azimuth plane. The switching of the main beam is analyzed and verified through full-wave simulation. The design presented is an improvement over a previous design of a two-element antenna array. The Friis transmission equation with polarization components taken into account is used to model the interchip wireless link. To verify the model, a transmission coefficient measurement is made between a pair of the two-element arrays separated by a 10 mm distance. Both simulated and measured radiation patterns of the two-element array are presented for use in the Friis equation to calculate the transmission coefficients. Full-wave simulation of the array pair is also performed. The calculated results obtained from the Friis model agree well with both the measured and full-wave simulation results. The Friis model is used to calculate both signal and interference levels.
