Multiband planar antennas are used as an efficient radiator in the field of mobile communication. In order to achieve excellent multiband characteristic of the antenna, a new type of multiband planar antenna fed by L-prove is developed and tested in this study. Several samples of the multiband planar antenna were fabricated, and various experiments were carried out in the C-band to estimate the performance of the antenna. The experimental results showed that this type of multiband planar antenna has excellent performances in terms of return-loss characteristic. The measured radiation patterns of the test antenna show also excellent performances in both on E-and H-planes. The computed results obtained from moment method were agreed well with the experimental results. By reason of described above, the basic design technique and radiation properties of this new type of antenna are obtained in this study. Therefore, this type of planar antenna is considered to be an effective model for a multiband planar antenna.

多频带平面天线在移动的通信领域中被用作高效辐射器。为了使天线具有良好的多频特性，本文研制了一种新型的L-prove馈电的多频平面天线。制作了多频段平面天线的几个样品，并在C波段进行了各种实验，以估计天线的性能。实验结果表明，这种多频带平面天线具有良好的回波损耗特性。测试天线的辐射方向图在E平面和H平面上都表现出良好的性能。矩量法计算结果与实验结果吻合较好。基于上述原因，本研究获得了这种新型天线的基本设计技术和辐射特性。因此，这种类型的平面天线被认为是一种有效的多频带平面天线的模型。
