Abstract

In this research paper, a pentagonal patch antenna has been designed on the 1.6 mm thick FR4 substrate material with a dielectric constant of 4.4 and a size of 66 x 55 mm2. To achieve the wideband characteristics, the rectangular slots are introduced along the 4 sides of the pentagon and the partial ground plane is used of size 20 x 55 mm2. The antenna is designed and simulated in the CADFEKO software using a line feed technique. The proposed antenna has an impedance bandwidth of 1.875 GHz with 3 resonant frequencies 1.7 GHz, 2.74 GHz & 3.259 GHz. The maximum gain for the proposed antenna is 8 dBi, reflection coefficient less than -10 dB and VSWR values are in the standard range. The proposed antenna design can be used for Digital Communication System (DCS 1800), Personal Communication System (PCS 1900), Wireless Broadband (WiBro 2300), Long Term Evolution (LTE 2300, LTE 2500), Bluetooth, Wireless Local Area Network (WLAN IEEE 802.1 b/g), Radio Frequency Identification (RFID), Worldwide Interoperability for Microwave Access (WiMAX) and Industrial Scientific Medical (ISM 2.4) applications.

一种用于无线应用的矩形槽宽带五边形贴片天线

本研究在1.6 mm厚、介电常数为4.4、尺寸为66 × 55 mm2的FR4衬底材料上设计了五边形贴片天线。为了实现宽带特性，在五边形的4边引入矩形槽，部分接地面的尺寸为20 x 55mm2。采用馈线技术在CADFEKO软件中对天线进行了设计和仿真。该天线阻抗带宽为1.875 GHz，谐振频率为1.7 GHz、2.74 GHz和3.259 GHz。该天线的最大增益为8dbi，反射系数小于- 10db，驻波比在标准范围内。所提出的天线设计可用于数字通信系统(DCS 1800)、个人通信系统(PCS 1900)、无线宽带(WiBro 2300)、长期演进(LTE 2300、LTE 2500)、蓝牙、无线局域网(WLAN IEEE 802.1 b/g)、射频识别(RFID)、微波接入全球互操作性(WiMAX)和工业科学医疗(ISM 2.4)应用。
