The experimental and simulation study of microstrip antenna with rectangular patch etched with L and inverted L slot is presented with band-notch nature for wireless frequency band operation. Designed antenna is housed in volume of 5 cm × 5 cm × 0.16 cm and operates between 4 and 18 GHz. The incorporating of L and inverted L slots results in split of resonating modes to exhibit the notch band property. The antenna shows the broadside nature of radiation characteristics with 3.76 dB gain at its operating frequency. The various antenna design parameters with specifications of the antennas are given and simulation, practical results are discussed in detail. The simulated, experimental results nearly match each other. Such a designed antenna may be used in SAR, X-band wireless systems applications.

提出了具有带缺口特性的矩形带L形和倒L形缝隙刻蚀微带天线的实验和仿真研究。设计的天线的体积为5厘米×5厘米×0.16厘米，工作频率为4至18 GHz。L槽和倒L槽的结合导致谐振模式的分裂，以展现出陷波带特性。该天线具有辐射特性的宽泛特性，其工作频率增益为3.76 dB。给出了具有天线规格的各种天线设计参数，并进行了仿真，详细讨论了实际结果。模拟的实验结果几乎彼此匹配。这样设计的天线可以用于SAR，X波段无线系统应用中。
