Abstract

This article reports the Modified Microstrip Feed Hybrid Rectangular Dielectric Resonator Antenna (RDRA). The proposed structure has a ground plane with a plus-shaped slot on an FR4 substrate with a height of 1.6 mm and dimensions of 38 mm x 35 mm. The proposed Dielectric resonator antenna is made of a material with 10 as its dielectric constant, and the dimensions of the DR are 19 x 20 x 18 mm3. The DR is connected to a modified microstrip feed with an octagonal ring through the plus-shaped slot in the ground. The proposed structure operates in frequencies from 2.60 GHz - 2.74 GHz, 3.12 GHz - 3.37 GHz, and 4.25 GHz - 4.37 GHz. The resonant frequency of the final proposed RDRA is 2.68 GHz, 3.26 GHz, and 4.31 GHz, which covers WLAN, WIMAX and Wireless Avionics Intra-Communications (WAIC) applications, respectively. The entire structure was simulated using the CST microwave studio. The simulated results agree with the measured results and both are presented. The compact size, stable radiation pattern and reasonable gain make this antenna suitable for the proposed applications.

用于无线三波段应用的改进微带馈电混合矩形介质谐振器天线

本文报道了一种改进型微带馈电混合矩形介质谐振器天线(RDRA)。该结构在FR4基板上具有一个加号型槽的接平面，高度为1.6 mm，尺寸为38 mm x 35 mm。所提出的介质谐振器天线采用介电常数为10的材料制成，DR的尺寸为19 × 20 × 18mm3。DR通过地面的加号槽连接到带有八角形环的改良微带馈电。所提出的结构工作在2.60 GHz - 2.74 GHz、3.12 GHz - 3.37 GHz和4.25 GHz - 4.37 GHz的频率范围内。最终提出的RDRA的谐振频率为2.68 GHz、3.26 GHz和4.31 GHz，分别适用于WLAN、WIMAX和无线航空电子内部通信(WAIC)应用。利用CST微波工作室对整个结构进行了模拟。模拟结果与实测结果吻合，并给出了两者的结果。该天线体积小，辐射方向图稳定，增益合理，适合上述应用。
