介绍了一种为PicoSat和其他通信小卫星提供圆极化(CP)辐射的紧凑型天线阵的设计和运行。所提出的阵列结合了折叠短路贴片(FSP)和曲折天线小型化。CP的实现是由一个由90度和180度弯曲形混合耦合器网络组成的紧凑的平面馈电电路实现的，它可以提供FSP元件的正交馈电，并可以集成到仅为5×5 cm(2)的天线接地面的背面上。在1.065 GHz下，实现的增益值大于3dBic，天线尺寸为0.17lambda(0)x 0.17lambda(0)。
The design and operation of a compact antenna array offering circularly polarized (CP) radiation for picosat and other small satellites for communication applications is presented. The proposed array combines the folded-shorted patches (FSPs) and meandering for antenna miniaturization. Realization of CP is achieved by a compact and planar feed circuit consisting of a network of meander-shaped 90 degrees and 180 degrees hybrid couplers, which can provide quadrature feeding of the FSP elements and can be integrated onto the backside of the antenna ground plane, which is only 5 x 5 cm(2). Agreement in terms of the simulations and measurements is observed with realized gain values of more than 3 dBic at 1.065 GHz and with an antenna size of 0.17 lambda(0) x 0.17 lambda(0).
