摘要

介绍了一种在氧化铝陶瓷基板上印刷的准八木天线阵列的设计、仿真、制作和测量。天线可用于空间要求有限的x波段(8GHz-12GHz)雷达应用。在雷达应用中,封装结构天线的温度上升很快,因此使用陶瓷基板也具有在高温条件下使用天线的优势。该阵列在电压驻波比为14 dB的情况下实现了52%的测量频率带宽。后瓣具有低电平,因此对其他封装电路的影响的总干扰被抑制。天线的最小线宽约为25um,因此在天线的制造过程中采用薄膜技术。

Design of a Quasi-Yagi Antenna Array Printed on a Ceramic Substrate
Design, simulation, production and measurement of a Quasi-Yagi Antenna array printed on an alumina ceramic substrate is presented. Antenna may be used in radar applications operating at X-band (8GHz-12GHz) with limited space requirement. Antenna in Package structure's temperatures rising up rapidly in radar applications so the use of ceramic substrates also has the advantage of using the antenna in high temperature conditions. The array achieves a measured 52% frequency bandwidth for voltage standing-wave ratio<2, 4–5 dBi absolute gain and >14 dB front to back ratio. Back lobes have low levels therefore the total interference which effects to the other package circuits are suppressed. The minimum line widths on the antenna is about 25 um so thin film technology is used in the fabrication process of the antenna.
