Abstract

In this paper, we propose a dual-band rectangular DRA using the strip-fed method for 2.4 GHz ISM and 4 GHz bands applications. The proposed antenna is composed of small ceramic dielectric (21.65 mm × 15 mm × 26.1 mm, alumina). In order to achieve our goals, we made a cylindrical perforation through the DRA. The measured bandwidth and maximum radiation gain are 2.35 – 2.48 GHz (VSWR ≪ 1.05, 8.54 dBi at 2.4 GHz) and 3.5– 4.52 GHz (VSWR ≪ 1.02, 8.29 dBi at 4.25 GHz), respectively. From these results, it is demonstrated that our proposed antenna can be applicable to the ISM and 4 GHz bands applications.

用于ISM和4ghz频段应用的双频矩形介电谐振器天线
在本文中,我们提出了一种用于2.4 GHz ISM和4 GHz频段应用的双频矩形DRA。该天线由小型陶瓷电介质(21.65 mm × 15 mm × 26.1 mm,氧化铝)组成。为了实现我们的目标,我们在DRA上做了一个圆柱形穿孔。测得的带宽和最大辐射增益分别为2.35 - 2.48 GHz (VSWR≪1.05,8.54 dBi, 2.4 GHz)和3.5 - 4.52 GHz (VSWR≪1.02,8.29 dBi, 4.25 GHz)。结果表明,所设计的天线可以适用于ISM和4ghz频段。
