现有的用于60-GHz无线个人区域网络通信的天线和阵列系统在掠射角处遭受固有的不良辐射。在这项工作中，这种限制是克服了高度集成的天线模块，结合了宽边和端射辐射器在一个单一的多层有机封装。液晶聚合物和Rogers RO 3003被用来实现小形状因子（12.5 mm × 10 mm × 1.3 mm）天线架构。共同设计的宽边和端射天线的特点和测量工作在57-66-GHz的频率范围。测得的8.7和10.9 dBi的宽边和端射天线，同时保持35-45-dB的两个天线之间的隔离度的增益。计算结果表明，侧射和端射单元的辐射效率分别为92.5%和78.5%。这些天线是正交极化的，适合频率复用。集成电路安装在凹腔内部，以实现具有波束切换或同时辐射的全有源天线模块。据我们所知，这是第一次出版的一个单一的封装多层集成的毫米波有源天线与方位角和仰角覆盖。
Existing antenna and array systems for 60-GHz wireless personal area network communications suffer from inherent poor radiation at grazing angles. This limitation is overcome in this work with a highly integrated antenna module that combines both broadside and end-fire radiators in a single multilayer organic package. Liquid crystal polymer and Rogers RO3003 are used to implement a small form factor (12.5 mm × 10 mm × 1.3 mm) antenna architecture. The co-designed broadside and end-fire antennas are characterized and measured for operation in the 57-66-GHz frequency range. Measured boresight gains of 8.7 and 10.9 dBi are achieved for the broadside and end-fire antennas while maintaining 35-45-dB isolation between both antennas. The numerically estimated radiation efficiency is found to be 92.5% and 78.5% for the broadside and end-fire elements. These antennas are orthogonally polarized and suitable for frequency reuse. Integrated circuits are mounted inside recessed cavities to realize a fully active antenna module with beam switching or simultaneous radiation. To the best of our knowledge, this is the first publication of a single package multilayer integration of millimeter-wave active antennas with both azimuth and elevation coverage.
