我们通过控制介质加载偶极子天线的表面电抗，研制了一种外套天线。首先，设计了一种假设具有理想金属表面片的外套天线，并通过控制外套的表面电抗获得了带阻特性。通过改变表面电抗的值，明确了天线工作频率和阻带频率之间的频率间隔的可变范围。其次，设计了一种使用垂直带状导体的外套天线，阐明了该天线的特性和工作原理。确定了阻带频率为1130 MHz，设计的天线具有36.3%的带宽(竖条S-11竖条
We developed a mantle-cloak antenna by controlling the surface reactance of a dielectric-loaded dipole antenna. First, a mantle-cloak antenna with an assumed ideal metasurface sheet was designed, and band rejection characteristics were obtained by controlling the surface reactance of the mantle cloak. The variable range of the frequency spacing between the operating and stopband frequencies of the antenna was clarified by changing the value of the surface reactance. Next, a mantle-cloak antenna that uses vertical strip conductors was designed to clarify the characteristics and operating principle of the antenna. It was confirmed that the stopband frequency was 1130 MHz, and the proposed antenna had a 36.3% bandwidth (vertical bar S-11 vertical bar
