摘要

本研究最终将为菲律宾从模拟电视向数字电视的转型提供很大的帮助。通过这项研究，在全面适应数字电视传输之前，一种新的室内数字微带电视天线将可供室内使用。设计的天线特定于677 MHz，目标特性:增益在-5 dB至-2 dB范围内，驻波比约为1.5，回波损耗为-10 dB，带宽为400 MHz。利用高频结构模拟器(HFSS)仿真工具，对677 MHz的天线进行了设计和优化。在PTV站服务覆盖区域附近最远2000 m的实际现场测量和测试，验证了矩形设计的最大增益为2.1623 dB，驻波比为1.595，回波损耗为-14.0905 dB，带宽为421.9 MHz。根据这些发现，设计的天线使用玻璃纤维印刷电路板作为材料，尺寸限制在17厘米× 17厘米。

Design of indoor microstrip TV antenna for integrated services digital broadcast — Terrestrial (ISDB-T) signal reception at 677 MHz

This study will eventually provide a great help to the Philippines in its transition from analog TV to digital TV. Through this study, just before the full adaptation of digital TV transmission, a new indoor digital microstrip TV antenna will be made available for indoor use. The antenna designed is specific to 677 MHz with target characteristics: gain in the range of -5 dB to -2 dB, VSWR of around 1.5, return loss of -10 dB and a bandwidth of 400 MHz. Through the use of simulation tool, High Frequency Structure Simulator (HFSS), the antenna was designed and optimized at 677 MHz. The actual field measurements and testing at the farthest distance of 2000 m around the service coverage area of PTV station helped in validating that the rectangular design has a maximum gain of-2.1623 dB, VSWR of 1.595, return loss of -14.0905 dB, and a bandwidth of 421.9 MHz. With these findings, the antenna designed was limited to a size of 17 cm by 17 cm using a fiber glass printed circuit board as the material.
