摘要：
PROBLEM TO BE SOLVED: To provide a method for simply determining delay time of an antenna for calculating the electrical length of an antenna.
SOLUTION: Two models of patch antennas 10 and 20 are prepared and disposed opposite to each other. Transmission characteristics S21 between input and output ports 14 and 24 of the two antennas 10 and 20 are found by means of electromagnetic field simulation. Delay time between the input and output ports 14 and 24 is found from the transmission characteristics S21. The delay time t2 of the antenna is found by multiplying by 1/2 a value obtained by subtracting propagation delay time t0 in free space with the two antenna models opposite standing therein from the obtained delay time t1.

要解决的问题：提供一种用于简单地确定用于计算天线的电长度的天线的延迟时间的方法。
解决方案：两个型号的贴片天线10和20被准备并彼此相对设置。 通过电磁场模拟，找到两个天线10和20的输入和输出端口14和24之间的传输特性S21。 根据传输特性S21找到输入端口14和输出端口24之间的延迟时间。 通过将自由空间中的传播延迟时间t0与从其获得的延迟时间t1相反的两个天线模型相减而获得的值乘以1/2 a来找到天线的延迟时间t2。 版权所有（C）2007，JPO＆INPIT
