本文提出了一种新型的单端馈电平面孔径天线（SPAA）采用低温共烧陶瓷（LTCC）工艺技术。首先提出了SPAA单元，它不仅继承了口径天线高增益、宽带宽的优点，而且具有低剖面、小尺寸的优点。该方法采用十字形贴片激励光阑，在贴片下方引入环形巴伦结构，将单端信号转换为差分信号驱动贴片。以这种方式，能量可以在贴片上以行进波形传播，并且以均匀的E场分布照射孔径。因此，天线实现了良好的电气和辐射性能，这是可比的平衡馈电的同行，同时处理一个简化的结构。测量结果表明，天线的阻抗带宽覆盖了60 GHz的免许可频段（57-64 GHz），最大增益可达11.5 dBi，腔体面积仅为27 mm 2。此外，利用基片集成波导馈电网络，该单元成功地扩展为4 × 4单元阵列，增益进一步提高到20.4dBi。测试结果表明，该阵列的阻抗带宽为57.5 ~ 65.7GHz，在工作频段内辐射性能稳定。
This paper presents new single-ended-fed planar aperture antennas (SPAAs) using low-temperature co-fired ceramics (LTCC) process technology. The SPAA element is proposed first, which not only inherits the merits of the aperture antennas including high gain and wide bandwidth but also exhibits advantages of low profile and compact size. The aperture is excited by a cross-shaped patch, and a loop-shaped balun structure placed below the patch is introduced to convert the single-ended signal into differential one to drive the patch. In this way, the energy can propagate on the patch in a traveling waveform and illuminate the aperture with uniform E-field distributions. Therefore, the antenna achieves good electrical and radiation performances, which are comparable to its balanced-fed counterparts, while processing a simplified structure. Measured results demonstrate that the impedance bandwidth of the antenna covers the 60 GHz license-free band (57–64 GHz), and the maximum gain can reach 11.5 dBi with a cavity area of only about 27 mm2. Furthermore, the element is successfully extended to a $4\,\,\times \,\,4$ element array using a substrate-integrated-waveguide based feeding network to further increase the gain up to 20.4 dBi. The measured results show that the impedance bandwidth of the array is from 57.5 to 65.7 GHz and the radiation performances are very stable over the operating frequency band.
