摘要： An electrically small supergain endfire transmitting and receiving array antenna comprising at least one first resonant element with a first input terminal. The first resonant element driven by a power supply voltage supplied at the first input terminal. The electrically small supergain endfire transmitting and receiving array antenna further includes at least one second resonant parasitic element with a second input terminal. The second input terminal shorted and the second resonant element spaced less than about 0.25λ from the first resonant element at any corresponding point. The antenna has a gain of at least 6 db and ka

摘要： A computerized process can design antennas using a completely deductive approach, that is, the desired electromagnetic properties are specified and the wire configuration that most closely produces the optimum result is synthesized. This new process uses a genetic algorithm in conjunction with an electromagnetic code. The genetic algorithm randomly selects a sample set of possible wire configurations from among all possible wire configurations. The performance of each configuration is computed using the electromagnetic code and ranked in order of quality. Partial solutions to this problem are obtained by "mating" the best wire configurations with one another. This evolutionary process is continued until an optimal wire configuration is obtained. Although this new process has only been tested on wire antennas, it can be used to design printed antennas, microstrip antennas, patch antennas and any other type of antenna that can be analyzed using an electromagnetic code.
摘要翻译：计算机化过程可以使用完全演绎的方法来设计天线，即指定期望的电磁特性，并且合成最接近产生最佳结果的导线配置。这个新过程使用遗传算法与电磁代码相结合。遗传算法从所有可能的线配置中随机选择可能的线配置的样本集。使用电磁代码计算每个配置的性能，并按质量顺序排列。通过将最佳导线配置彼此“交配”，可以获得对此问题的部分解决方案。这个进化过程一直持续到获得最佳的配线。虽然这种新工艺仅在有线天线上进行了测试，但它可用于设计印刷天线，微带天线，贴片天线和任何其他类型的可以使用电磁码分析的天线。

摘要： A double-folded monopole is used on a linear antenna to produce a traveling-wave distribution of current. The double fold is positioned one-quarter wavelength from the end of the antenna. The resultant antenna has three radiating elements that are orthogonal with respect to each other. The orthogonal folded dipoles each consist of five segments designed so that the currents have comparable magnitudes and are in phase to provide near hemispherical coverage.
摘要翻译：在线性天线上使用双折叠单极子以产生电流的行波分布。双折叠位置距离天线端部四分之一波长。所得到的天线具有相对于彼此正交的三个辐射元件。正交折叠偶极子每个由五个片段组成，这些片段被设计成使得电流具有可比的大小并且同相以提供近半球形的覆盖。
