Introduction

In the field of atmospheric science, collecting data such as air pressure, temperature, humidity, wind speed, and direction is crucial for understanding the behavior of the atmosphere. One effective method for collecting this data is by flying radiosondes at a certain height above sea level. To ensure continuous data transmission between the radiosonde and receiving stations, an antenna with high gain and an appropriate beamwidth is required. The Yagi-Uda Stacking Antenna, made of aluminum, is a suitable choice for the work frequency of 433 MHz. This study aims to design and compare two types of Yagi-Uda antennas with different stacking configurations, namely vertical and horizontal, to achieve the desired specifications while reducing the weight of the antenna at the receiving station.

Background

Antenna design is a critical aspect of wireless communication systems, and the choice of antenna configuration can significantly impact the performance of the system. The Yagi-Uda antenna is a popular choice for wireless communication systems due to its high gain and directional beamwidth. However, the stacking configuration of the antenna can affect its performance, and vertical and horizontal stacking are two common configurations used in antenna design. In this study, we aim to compare the performance of vertical and horizontal stacking Yagi-Uda antennas for application at 433 MHz.

Methodology

The antenna design was carried out using MMANA-GAL software, a popular antenna design software that allows users to design and simulate various types of antennas. The simulation results were used to compare the performance of the two antenna configurations, namely vertical and horizontal stacking. The comparison was based on several important parameters, including Voltage Standing Wave Ratio (VSWR), Gain, Return Loss, and Bandwidth.

Simulation Results

The simulation results showed that the vertical stacking configuration achieved a higher gain value of 18.76 dB compared to the horizontal stacking configuration, which reached 18.67 dB. The VSWR parameter also showed a significant difference between the two configurations, with vertical stacking recording a value of 1.2, while horizontal stacking showed a slightly higher value of 1.24.

Direct Measurement

Direct measurement of the two antennas using a VNA meter (Anritsu MS2034B) gave attractive results. The antenna with vertical stacking showed the best performance, with a VSWR value of 1.45 and Return Loss reaching -19.17 dB. Conversely, the horizontal stacking configuration had a VSWR value of 1.64 and Return Loss of -8.2 dB. Although both configurations showed good performance, the vertical stacking configuration showed excellence in terms of more optimal efficiency and signal reception.

Comparison of Bandwidth

Both types of antenna stacking had the same bandwidth, which was 10.184 MHz. This shows that although there were differences in gain performance, VSWR, and Return Loss, both configurations still had the same ability in terms of acceptable frequency ranges.

Conclusion

From this analysis, it can be concluded that vertical stacking is superior in several important aspects needed in the antenna application for the radiosonde receiving station. These advantages make vertical stacking more recommended for use in systems that require stable and reliable data transmission. This study not only provides new insights in antenna design but can also make a significant contribution in the development of communication technology for atmospheric applications.

Recommendations

Based on the results of this study, the following recommendations can be made:

  • Vertical stacking is recommended for use in systems that require stable and reliable data transmission.
  • Further studies can be conducted to investigate the performance of other antenna configurations, such as diagonal and triangular stacking.
  • The use of MMANA-GAL software can be explored for designing and simulating other types of antennas.

Future Work

This study provides a foundation for further research in the field of antenna design and communication technology for atmospheric applications. Future studies can be conducted to investigate the performance of other antenna configurations, such as diagonal and triangular stacking, and to explore the use of MMANA-GAL software for designing and simulating other types of antennas.

Limitations

This study has several limitations, including:

  • The study only compared the performance of vertical and horizontal stacking configurations.
  • The study only used MMANA-GAL software for designing and simulating the antennas.
