摘要：
在任何无线通信网络和系统中，天线是沿着电信号的传播路径的重要元件。天线模块是自动驾驶系统的重要组成部分，它应该在dGPS，高清地图校正服务以及无线电和导航系统中发挥作用。本工程研究工作的主要范围包括评估和确定GPS/GLONASS贴片与RF GPS L1（1.57542 GHz）贴片天线特性的性能参数和特性。FEKO仿真研究进行了广泛的比较，作出评估和评估的特性和性能参数，如平均/无源增益的建议天线在存在背景噪声。在FEKO模拟研究开始之前，通过数字仪器对以下内容进行物理机械尺寸测量：辐射元件尺寸：实际长度（L）和宽度（W），衬底材料尺寸：衬底长度（Lsub）、宽度（Wsub）和高度（h）。提出了工作在1.57542 GHz的GPS贴片天线和谐振在1.5925 GHz的双频贴片天线的天线模型。具体来说，这项工作提出了设计，建模，确定无源增益的RF GPS L1贴片与双频贴片天线与汽车系统和空间内的预期目标应用。仿真分别生成RF GPS L1贴片和双频贴片天线结构，以评估所提出的双频天线的性能。进行模拟而不是数学建模。本文的重点是如何获得GPS与双频天线的等效总无源增益。
英文摘要：
In any wireless communication network and system an antenna is an important element along the propagation path of an electrical signals. Antenna module is a vital component of automated driving systems, it should function as needed in dGPS, HD map correction services, and radio and navigation systems. The main scope of this engineering research work involves the evaluation and determining the performance parameter and characteristic of the GPS/GLONASS patch vs RF GPS L1(1.57542 GHz) patch antenna characteristic. FEKO simulation studies are carried out to extensively compare, make an assessment and evaluate the characteristic and performance parameter, such as the average/passive gain of the proposed antenna in the presence of background noise. Prior to the start of the FEKO simulation studies, a physical mechanical dimension measurements via a Digital instrumentation were conducted for the following: Radiating Element Size: The actual length (L), and width (W), Substrate Material Size: The substrate length (Lsub), width (Wsub), and height (h). The proposed antenna model for GPS only patch antenna operating at 1.57542 GHz and the dual band patch antenna resonating at 1.5925 GHz are developed. To be specific, this work presents the design, modeling, determining passive gain of the RF GPS L1 patch vs. dual band patch antenna with intended targeted applications within the automotive system and space. Simulation are undertaken to generate the RF GPS L1 patch and dual band patch antenna structure respectively for the sole purpose of evaluating the performance of the proposed dual band antenna. Simulation are performed rather than mathematical modelling. The emphasis of this paper is how to obtain the equivalent amount of total passive gain in a GPS vs. that of dual band antenna.
