Introduction

In recent years, the demand for digital television broadcasts has increased significantly, especially in urban areas. However, the availability of digital television broadcasts is still limited in many areas, including the city of Medan. One of the main challenges in receiving digital television broadcasts is the lack of effective antennas that can receive signals efficiently. In this article, we will discuss the design of a flower pot antenna that is intended to be used as an antenna receiving digital television broadcasts in the city of Medan.

Background

The city of Medan is a major urban center in Indonesia, with a population of over 2 million people. However, the availability of digital television broadcasts in the city is still limited, with many areas experiencing poor signal reception. One of the main reasons for this is the lack of effective antennas that can receive signals efficiently. In this study, we aimed to design an antenna that can receive digital television broadcasts in the city of Medan, with a focus on improving signal reception performance.

Design of the Flower Pot Antenna

The flower pot antenna is a type of antenna that is designed to resemble a flower pot. The antenna operates in the Ultra High Frequency (UHF) frequency range between 530 to 650 MHz. The basic structure of the antenna consists of the upper radiator (λ/4), the lower radiator (λ/4), and the length of the choke resonant. The upper radiator component has a tolerance of 11%, the radiator lower 13%, and the length of the choke resonant is 7.5%.

Measurement of Antenna Parameters

In this study, the antenna parameter was measured using a vector network analysis (VNA) which included Return Loss, Voltage Standing Wave Ratio (VSWR), and Bandwidth. There are two designs produced, namely the initial design and optimal design. In the initial design, the return loss value only reaches -4.11 dB and VSWR of 2.70 at a frequency of 530 - 650 MHz. Conversely, in the optimal design, the value of the Return Loss parameter increased to -12.85 dB and VSWR dropped to 1.59.

Additional Analysis and Explanation

Success in designing a flower pot antenna shows the potential for innovative in creating antennas that not only function properly but also aesthetically. With the placement of antenna in a 3 meter high flower pot and connected to the port cable on a digital television, the test results show that the average signal level received reaches 52.14%, with signal quality reaching excellent numbers of 99%.

Increased design from the beginning to optimal provides a deeper understanding of the effect of antenna parameters on signal reception performance. A better return loss shows that the antenna is more efficient in receiving signals and reducing the reflected waves, while the decrease in VSWR shows that the antenna is able to transmit more effective power.

Importance of Antennas that can be Integrated with the Surrounding Environment

The importance of antennas that can be integrated with the surrounding environment is also an added value of this design, especially for users who want devices that are not only functional but are also able to integrate with their home garden aesthetics. In the context of the development of digital technology, the presence of antennas like this is very relevant, especially in areas that may still have challenges in signal reception.

Conclusion

In conclusion, the design of this flower pot antenna not only prioritizes technical aspects, but also provides practical solutions for the people of Medan in obtaining high-quality digital TV broadcasts. With the application of the right design, this antenna can be an attractive choice for users who crave broadcast quality without sacrificing the aesthetics of their homes.

Future Work

Future work can focus on improving the design of the flower pot antenna, with a focus on increasing the signal reception performance and reducing the size of the antenna. Additionally, the design of the antenna can be modified to accommodate different types of digital television broadcasts, such as satellite TV or cable TV.

Limitations of the Study

One of the limitations of this study is the use of a vector network analysis (VNA) to measure the antenna parameters. While the VNA is a widely used tool for measuring antenna parameters, it may not provide accurate results in certain situations. Additionally, the study only focused on the design of the flower pot antenna, and did not consider other types of antennas that may be available for digital television broadcasts.

Recommendations for Future Research

Based on the results of this study, we recommend that future research focus on improving the design of the flower pot antenna, with a focus on increasing the signal reception performance and reducing the size of the antenna. Additionally, the design of the antenna can be modified to accommodate different types of digital television broadcasts, such as satellite TV or cable TV.

Conclusion

In conclusion, the design of the flower pot antenna is a promising solution for improving signal reception performance in digital television broadcasts. With its unique design and ability to integrate with the surrounding environment, this antenna can be an attractive choice for users who crave broadcast quality without sacrificing the aesthetics of their homes.
