Abstract

A medium-gain Grid Array Antenna (GAA) is developed and manufactured in ESL41110, a low εr Low Temperature Co-fired Ceramics (LTCC) from ElectroScience Laboratory. The antenna dimensions are 12 mm × 12 mm × 0.3 mm and it has a measured impedance bandwidth from 135 to 142 GHz, with a boresight maximum gain of 7.96 dBi and vertical beams. In order to realize this antenna, new LTCC fabrication steps had to be developed and qualified in the in-house procedure, including laser ablation of gold in the green state as well as after sintering.

用于d波段应用的低介电常数LTCC的QFN封装网格阵列天线

采用电子科学实验室的低εr低温共烧陶瓷(LTCC) ESL41110研制了一种中增益栅极阵列天线(GAA)。天线尺寸为12mm × 12mm × 0.3 mm，测量阻抗带宽为135 ~ 142ghz，轴向最大增益为7.96 dBi，垂直波束。为了实现这种天线，必须开发新的LTCC制造步骤，并在内部程序中进行验证，包括在绿色状态和烧结后对金进行激光烧蚀。
