“…Carrel, in 1961, introduced a mathematical model for the analysis of LPDA, the results of which agreed reasonably well with the experimental values [11]. A PLPDA with 12 dipoles suitable to operate in a frequency band between 0.8 GHz and 2.5 GHz was designed in [12]. The realized antenna presented a reflection coefficient lower than −12 dB and a gain ranging between 4.5 dBi and 6.3 dBi in the band of interest.…”

An antenna operating between 300 MHz and 700 MHz, designed to be used on a ground penetrating radar installed on an Unmanned Aerial Vehicle (UAV) for the exploration and characterization of the buried ice deposits on Mars, is presented. To this end, a lightweight, high-gain Vivaldi antenna having compact dimensions and high operating bandwidth has been taken into consideration. This antenna, equipped with circular-loaded rectangular slots etched on its radiating arms, exhibits improved performance in terms of size, return loss, gain, and fidelity factor with respect to a conventional antipodal Vivaldi antenna. Experimental measurements performed on a prototype of the Vivaldi antenna with slots showed a return loss lower than −12 dB with realized gains between 4 dBi and 6.5 dBi in the 300-700 MHz frequency band.

“…Data on the distribution and amount of emission of electromagnetic waves from all directions and various frequency ranges are required for the mitigation process. Measuring instruments that can measure electromagnetic interference, in general, are antennas that have specifications for a wide frequency range (wideband), high gain, compact size, and, where possible, low cost to manufacture [16]. Based on this, the discone antenna has the required specifications because it has a wideband (wide frequency range), compact size, high gain, and omnidirectional property (the ability to capture emission from all directions) needed for this measurement [17], [18].…”

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.

“…Ref. [31] offered PLPDA of (0.8-2.5) GHz bandwidth using 12 dipole elements with a small size. These 12 dipoles were arranged in a way so that the length of each one decreases gradually relative to the next one, and each dipole resonates at its center frequency to cover the overall EMC spectrum L-band.…”

This article presents the design, modeling, and fabrication of a printed log-periodic biconical dipole array antenna (PLPBDA) for electromagnetic compatibility (EMC) measurements. The proposed structure used bow tie-shaped dipoles instead of typical dipoles to achieve a size reduction of 50% and bandwidth enhancement of 170% with the help of PCB technology. Furthermore, the balanced feeding method and the modifications in bow tie-shaped dipole dimensions were utilized to obtain broad bandwidth of 5.5 GHz (from 0.5 GHz to 6 GHz). This structure comprises 12 dipole elements with a compact size of 170 × 160 × 1.6 mm, reflecting low fluctuations gain of about (4.6–7) dBi with the help of an extra dipole. Moreover, the achieved frequency and radiation characteristics (simulated and measured) agree with each other and are compatible with the results of classical EMC antennas. The achievements of this structure showed promising results compared to both literature reviews and reference antenna Hyper LOG® 7060 offered for sale.
