New types of antennas such as Substrate Integrated Waveguide (SIW) antennas are being used for high frequency applications. In this paper, the development of an array of novel slotted SIW epsilon near zero (ENZ) antenna is presented. Due to the limited fabrication facilities, the study is conducted in the 5 GHz band. The effective permittivity falls to zero at the cut off frequency of the waveguide. This impact is utilized to make an effective ENZ material in an ENZ super tunnelling waveguide. The design of 1 × 2, 1 × 4 antenna array is presented. The design of microstrip power dividers for feeding the array element is discussed. The presented antenna array achieve higher gain than the previously designed antennas. The prototype of the 1 × 4 SIW ENZ antenna array is fabricated and the measurement results are compared with the simulated studies. This work pertains to investigation on the array of SIW antennas for millimetre wave applications.

5 GHz高增益缝隙SIW epsilon接近零天线阵列，用于无线通信

新型天线，例如衬底集成波导（SIW）天线，正在用于高频应用。在本文中，提出了一种新型的缝隙式SIW epsilon近零（ENZ）天线阵列的开发。由于制造设备有限，该研究在5 GHz频段内进行。有效介电常数在波导的截止频率处降至零。利用这种影响，可以在ENZ超隧穿波导中制成有效的ENZ材料。介绍了1 ×  2、1  ×  4天线阵列的设计 。讨论了用于馈送阵列元件的微带功率分配器的设计。提出的天线阵列比以前设计的天线获得更高的增益。1 ×的原型  制作了4个SIW ENZ天线阵列，并将测量结果与仿真研究进行了比较。这项工作涉及对毫米波应用的SIW天线阵列的研究。
