It is promised that the lobe pattern and impedance of a antenna are kept common in a wider frequency field (as bandwidth is 10 or more).
通常希望一个天线的波瓣图和阻抗能在一个较宽的频率范围内(例如频带宽度为10或更高)保持不变。
Through a new feeding construction with phase-shifter, the main lobe of the pattern of the microstrip leaky-wave antenna can scan at a fixed frequency.
通过控制微带漏波天线中部馈电端口移相器,成功实现了工作频率固定下微带漏波天线主波束扫描,并使用电子开关实现微带漏波天线主波束双向扫描。
This paper analyses the pattern function of DBF in subarray. The designing method for directivity pattern is given and the condition of producing the grating lobe is discussed.
