ABSTRACT The modified ends-fed dipole-like antenna that is fed by a hybrid ring is dwelt upon in this paper. The two energized ports of the hybrid ring provide simultaneous sum and difference radiation patterns. A printed circuit board prototype was simulated through the full-wave solver “CST Studio Suite” and successfully implemented. The measured results confirm the proposed approach. The input reflection coefficient for both the ports and isolation between them are better than (−15) dB. The proposed antennas can easily be integrated with monolithic electronic circuits and may find applications in high-frequency devices including wireless communication systems, radars, and so on.

具有同步和差辐射模式的新型双端口混合环形偶极子天线

摘要 本文研究了一种由混合环馈电的改进型端馈电偶极子天线。混合环的两个通电端口同时提供和和差辐射模式。通过全波求解器“CST Studio Suite”模拟印刷电路板原型并成功实现。测量结果证实了所提出的方法。两个端口的输入反射系数和它们之间的隔离度都优于 (-15) dB。所提出的天线可以很容易地与单片电子电路集成，并且可以在包括无线通信系统、雷达等在内的高频设备中找到应用。
