Design of Microstrip Antennes for Use in Digital Television Network Systems

The quality of television networks in Indonesia is still undergoing continuous development in order to provide the best quality of the television network, but what remains the problem is the decline in the quality of such television network that is still not covering the entire territory of Indonesia. This requires additional supporting devices to be able to overcome the problem. In this study, a microstrip antenna was created using the array method, to work at a frequency of 400-900 MHz for digital television networks. The microstrip antenna will be observed and analyzed on the return loss (S-11), VSWR (Voltage Standing Wave Ratio), bandwidth, and gain antenna parameters. The simulation results for some parameters such as returnloss which has a value of -13.33639 dB and the VSWR value is obtained as 1.5489645 at a working frequency of 650 MHz. It already meets the criteria of a good microstrip antenna and is ready for manufacture and implementation.
