Fifth generation (5G) cellular networks have evolved rapidly to address the demand for faster, reliable and scalable connectivity in today's digital era. One of the key aspects in this evolution is the utilization of multiple-input multiple-output (MIMO) to increase network capacity and performance. In this research, we focus on developing and evaluating the performance of triangular array MIMO antennas especially for applications in 5G networks. In this paper, we propose a triangular array MIMO antenna design approach that combines the advantages of triangular geometry with MIMO technology. We describe a design methodology involving antenna element selection, array configuration, and spatial arrangement. The influence of these parameters on system performance is explored through simulation and field-based testing. Our experimental results reveal that this triangular array MIMO antenna shows potential in increasing network capacity and reducing inter- channel interference. We analyze antenna performance in terms of signal gain, throughput capacity, connection stability and spectral enhancement. Compared to traditional MIMO antennas, this triangular approach provides a significant increase in terms of network capacity and carrying capacity. We also discuss the challenges and opportunities associated with the practical implementation of triangular array MIMO antennas in a 5G network environment. Factors such as physical size, energy efficiency and circuit complexity are studied to provide insight into optimal deployment scenarios. Overall, this study illustrates the potential of triangular array MIMO antennas as a promising solution to improve 5G network performance. Our results and findings can provide guidance for further developments in dealing with connectivity challenges in the modern wireless communications environment.

VHF Air to Ground (VHF A/G) is a radio communication equipment used as a means of communication between the Air Traffic Controller (ATC) and the pilot. If communication is lost between the controller and the pilot, it will be fatal and can endanger flight safety. Therefore, the authors designed a monitoring in order to minimize the risk of this incident.

VHF A/G radio operating at the Banjarmasin branch company of Airnav already has a monitoring system. However, currently the radio monitoring used can only display the status of the equipment. So that a design is carried out that can display the status, parameters, changeover, alarm and alarm sound when a fault occurs on the radio. The existence of this monitoring control can help technicians to see a more detailed status with the help of parameter readings according to the radio, and can immediately make changeovers if there are parameters that are close to the alarm tolerance limit. So that technicians can anticipate radio communication interruptions (shutdowns) caused by alarms and this allows the equipment to continue operating normally.

The results of the design show that testing status, parameters, alarms and setting the value of parameter types can also be displayed at the same time equipped with a sound system when the alarm sounds. Switching between TX1 and TX2 is possible. And then, there are delay when the user change the setting and changeover between 1,5 second until 3.7 second
