“…This feature is valuable in the following design steps to obtain the optimum dimensions of the PLPDA antenna. It can be concluded that keeping the starting points of the electromagnetic waves close to each other directly impacts broadening the bandwidth [1], which is why the biconical dipole has wider bandwidth than the conventional one.…”

“…With the rapid growth of wireless communications, the need to use Ultra-wideband antennas in such systems has appeared in various applications. Furthermore, the antenna design is the key to every wireless system since it can control its radiation characteristic according to the application's specifications [1]. Ultra-wideband antennas are used in different applications, e.g., in radio systems for communications and in electromagnetic compatibility (EMC) for measurement applications.…”

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 various advantages of reconfigurable antennas, however, come with a couple of drawbacks, such as the need for additional antenna modification, which necessitates a more complex regulation. Full usage can necessitate sophisticated signal processing and feedback circuits, and more components and more complex manufacturing processes would almost certainly be required than in traditional antenna system embodiments [10]. For example, the authors in [11] antenna performance-based 7 PIN diodes that limit their use in many portable and handheld devices.…”

a reconfigurable antenna design for 5G applications is presented. It is based on monopole antenna and fractal structure. The design structure is consisted of (monopole) feedline, ground plane, L-shape reflector, fractal structure and PIN diodes. The antenna is printed on (25×29×1.6 mm3) FR-4 substrate of εr=4.3 and tanδ =0.001. The antenna shows a resonant frequency at 4.1 GHz with S11=-11.4 dB and Omni-direction pattern of 1.21 dB gain. The L-shaped reflector is used to maintain the radiation pattern in a specific direction. Moreover, the proposed fractal structure is found to operate as a circuit to give another resonant frequency and enhance the antenna performance. Where it is used to give more manipulation in the antenna performance including: frequency resonance and radiation patterns. The PIN-diodes are used to give many cases for more current manipulation. moreover, the authors used RF (50 SMA port) between monopole antenna and right side of ground plane to optimize directing radiation pattern and to eliminate the problems of interference between AC and DC current that produced from using PIN diode. This manipulation leads to change the resonant frequency and radiation pattern to the desired direction.So all parts are printed on a single side of FR4 substrate
