Abstract

In this work, an OFF-Centered fed dipole slot antenna with a reduced ground plane for multiband wireless communication is discussed. The proposed design works at GPS/Galileo (1.13- 1.32) GHz, LTE band 3 (1.6 – 1.88) GHz, LTE (2.60 – 3.0) GHz and WLAN (4.92 – 5.50) GHz for −10 dB reference value of the return loss (Reflection coefficient). The design has microstrip feedline followed by a quarter wave transformer. Slots were introduced in both the poles for size miniaturization and also to improve impedance bandwidth, gain and efficiencies. The antenna performance is evaluated in terms of impedance bandwidth, gain and radiation pattern. Moreover, introduction of the slots helps to get an additional resonance frequency. The design is fabricated, and results are measured for the fabricated design. Simulated results show close resemblance with measured results.

用于多波段无线应用的小型化偏心馈电偶极子槽天线

本文讨论了一种适用于多波段无线通信的离心馈电偶极子槽天线。所提出的设计工作在GPS/Galileo (1.13 ~ 1.32) GHz、LTE频段3 (1.6 ~ 1.88)GHz、LTE (2.60 ~ 3.0) GHz和WLAN (4.92 ~ 5.50) GHz，回波损耗(反射系数)参考值为- 10 dB。该设计采用微带馈线接四分之一波变压器。在两极中引入槽是为了尺寸小型化，也为了提高阻抗带宽、增益和效率。从阻抗带宽、增益和辐射方向图等方面对天线性能进行了评价。此外，引入槽有助于获得额外的谐振频率。对设计进行了加工，并对加工后的设计结果进行了测量。模拟结果与实测结果接近。
