提出了一种适用于下一代无线系统的片上毫米波相控阵天线。目前的硅基毫米波天线由于衬底有损耗，辐射效率较低(~5-10%)。所提出的片上天线阵列采用微电子机械系统(MEMS)工艺可以达到80%的辐射效率。通过悬挂辐射天线，形成了低ε的空气衬底，而不是有损耗的硅衬底。所设计的5×5(单元)阵列在60 GHz范围内匹配良好，带宽为2 GHz，回波损耗至少为-10dB。该阵列的峰值实现增益为19.7dBI，旁瓣电平为-13db。所设计天线的最大扫描体积在H面上为±45°，在E面上为±48°。作为一种片上天线，所提出的阵列可以单片集成在硅衬底上。此外，与其他阵列不同的是，它在E面和H面都能满足较高的实现增益和适中的扫描体积，是下一代通信系统的理想选择。
This paper presents an on-chip millimeter-wave (mmW) phased array antenna for the next-generation wireless systems. Current silicon-based mmW antennas exhibit low radiation efficiency (~5-10%) due to lossy substrate. The proposed on-chip antenna array can achieve radiation efficiency >80% using micro-electro-mechanical systems (MEMS) processes. By suspending the radiating antennas, a low-εrsubstrate of air is formed instead of a lossy silicon substrate. The designed 5×5 (element) array is well matched at 60 GHz covering a bandwidth of 2 GHz with at least -10 dB return loss. The peak realized gain for this array is 19.7 dBi with the side-lobe level of -13 dB. Moreover, the maximum scanning volume of the designed antenna is ±45° in H plane and ±48° in E plane. As an on-chip antenna, the proposed array can be monolithically integrated on a silicon substrate. Moreover, unlike other arrays, it satisfies high realized gain and moderate scanning volume in both E and H planes, making it desirable for the next-generation communication systems.
