“…Calculating the antenna factor and comparing it with the standard result of the conventional LPDA antenna is a trusted investigation method to show the validity of the proposed design. For instance, an antenna factor (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41) dB/m for the proposed design is compared to the antenna factor (26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41) dB/m for a commercial (0.7-6) GHz LPDA antenna (HyperLOG ® 7060). Moreover, more investigations could be performed on this antenna for future work, such as the calibration and modeling of an equivalent circuit.…”

“…In PLPDA, all the parameters of the conventional LPDA antenna are divided by the square root of the effective dielectric substrate ( √ ε e f f ). The majority of EMC reference antennas are dedicated to serving in the band starting from 700 MHz to 2.4 GHz since this band is occupied by different applications such as GSM 850-900 MHz, mobile 1800 MHz, 3G 2100 MHz, and Wi-fi 2400 MHz and has a high probability to interference [24]. On the other hand, the band from 2.5 GHz to 6 GHz must be taken into account due to the fact it is occupied with another set of critical applications such as WiMAX 3.5 GHz and 5.3 GHz, mid bandwidth for 5G 2.5-3.8 GHz, PAN 4.8 GHz, and WLAN 5.8 GHz [25].…”

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.

“…The antenna system (AS) of this direction finder is based on two orthogonal [22] direction-finding pairs (DF) [23], oriented in the north-south and east-west directions. Each pair consists of two biconical antennas with [24] and spaced apart from each other by a distance of 2𝑑 as shown in Figure 3. This configuration is designed to solve the problem of detection and disambiguation in determining the direction of a UAV [25].…”

This scientific article presents a block diagram of a two-channel radio direction finder that effectively uses the phase method to determine the direction of the signal source. The main attention is paid to the mathematical model of the formation of the cardioid radiation pattern of biconical antennas, which have unique directivity characteristics. These features significantly affect the accuracy and reliability of the bearing determination process. The developed algorithm aims to accurately determine the direction of motion of an unmanned aerial vehicle, especially in the context of a two-channel radio receiver and a five-element antenna system. This antenna system provides unique capabilities for increased resolution and directional accuracy. The article also touches on the issue of software implementation of the developed algorithm, which is aimed at increasing the number of generated bearing estimates in conditions of limited time for observing an unmanned aerial vehicle. Thus, the proposed method is of interest in the field of precision direction finding in the context of small unmanned vehicles.

“…The United Kingdom (UK) government adopted laws in 1992 to force the manufacturers of all electronic devices or appliances to submit their products to the EMC test before releasing them to the markets. One of the mandatory parts of the EMC test is the electromagnetic sensors (reference antenna and electric/magnetic probe) [ 8 , 9 , 10 ]. The EMC measurement consists of two methods; the far-field method uses the reference antenna to estimate/radiate the electrical field strength (E max ) and it is recommended when the level of source interference is significantly high [ 11 ].…”

This paper presents a printed magnetic probe that can switch from broadband to tunable narrowband for near-field measurement. In the early design stage, we created a printed loop gap resonator as a magnetic reference sensor for the pre-compliance test in a band up to 6 GHz. Consequently, the results showed a good response in terms of the S11 and S21 parameters of the proposed probe compared with the commercial magnetic sensor XF-R 3-1. The source noise might spread among different frequency bands, making the broadband magnetic probe the closest choice for estimating the magnetic field in the near-field region. Unfortunately, broadband magnetic probes have lower sensitivity than narrowband ones. One of the solutions to get high sensitivity is to connect the LNA to the output of the passive magnetic sensor. This work proposes a novel method to solve this issue using a PIN diode to change the broadband status into a high sensitivity narrowband status and then tune this narrowband across the most critical applications such as 3.5° GHz, 3.75° GHz, 4.8° GHz, and 5.2° GHz with the help of a varactor diode. Compared to the broadband status, an improvement of more than 10 dB has been obtained across all these wireless bands. Furthermore, the proposed structure’s isolation between the electrical and magnetic fields is about 13 dB.
