我们描述了一种天线，它将在大约1225 MHz到1630 MHz的频段内工作，从而覆盖GPS和Iridium频率。该天线在仰角约为5/spl deg/时辐射标称的右侧圆极化，并采用遗传算法(GA)和电磁代码相结合的工艺进行设计。在该方法中，指定了波束宽度、驻波比和频带，并综合了与这些特性最接近的天线配置。
We describe an antenna that will operate over the band from about 1225 MHz to 1630 MHz and thus cover both GPS and Iridium frequencies. This antenna radiates nominal right hand circular polarization at elevation angles above about 5/spl deg/ and was designed with a process that uses a genetic algorithm (GA) in conjunction with an electromagnetic code. In this method the beamwidth, VSWR and frequency band are specified and the antenna configuration that most closely produces these characteristics is synthesized.
