“…The discone antenna was designed according to [23] in the 0.7-6 GHz frequency range following the wireless frequency range of medical equipment: 0.915 GHz for RFID, 2.4 GHz for WLAN/Bluetooth, and 5.2 and 5.8 GHz for WLAN. Using minimum frequency (𝑓 𝑚𝑖𝑛 ), the wavelength (λ) was found to be 428.6 mm through a calculation using (2).…”

“…As the antenna was made manually, the level of precision was not good. The comparison of S11 measurement between the discone antenna designed in the previous study [23] and the Design B discone antenna is shown in Figure 9. At the frequency of 0.915 and 2.4 GHz, the S11 values of the Design B discone antenna were higher, but the Design B discone antenna still had good performance because the S11 values remained below -10 dB.…”

“…In [22], a discone antenna was designed for use in radio frequency interference measurements, in which case, based on its S11 value, it works in the 1.42-2.14 GHz frequency range. In [23], a discone antenna was designed for interference measurements in medical devices with a copper sheet as its material, in which case it works across a wide frequency range, 0.7-6 GHz. Based on previous studies, the discone antenna design, when viewed from its S11 value, has a wider working frequency coverage, but at the 5.2 GHz frequency, it does not have an optimal S11 value.…”

“…It requires optimization [23] so that the designed discone antenna can be used for wireless electromagnetic interference measurements in all medical device frequency ranges. If the discone antenna can operate well in these frequency ranges, then measurements of electromagnetic field radiation emissions can be carried out and the results of these measurements can later be used to mitigate potential interference.…”

The wide spread of the Internet of Things creates the possibility of electromagnetic interference in medical devices. Therefore, it is necessary to perform risk mitigation by finding the value of electromagnetic interference through measurements using wideband and omnidirectional antennas, e.g., the discone antenna. In this research, the optimization of the S11 value of a designed discone antenna was obtained using simulation from the effect of dimensional variations in discone parameters like disc diameter, cone bottom diameter, gap, and cone height on S11 characteristics. The parameters were combined for optimization. The design was fabricated, and the S11, radiation pattern, gain value and antenna factor, and the ability to measure interference through modeling were measured. Gain value and antenna factor were obtained using the gain-comparison method, which compared the antenna of interest against another antenna with a standard gain. The optimization was successfully performed with a better S11 value. At 5.2 GHz, the value of S11 was below -10 dB. The realization of the design showed similar results to the simulation, and it was found to be able to operate in the medical device frequency range (wideband). The ability of the discone antenna improved in terms of S11 value, especially at 5.2 GHz, where the value was below -17.443 dB. The radiation pattern of the designed antenna is omnidirectional. Additionally, validation was carried out by providing gain value and antenna factor. It has been proved that the designed discone antenna could measure interference successfully by modeling interference sources as electric field sources from all directions.
