“…In [6] Shandal et al proposed a pentagon slot [7] inside fractal circular patch microstrip resonator to design compact antenna over partial ground plane that is introduced using the third iteration of adopted fractal geometry. Similar works are proposed in the papers such as in [8] a miniaturized ultra-wideband (UWB) antenna based on Sierpinski square slots is reported [9]. Antenna miniaturization is achieved by etching Sierpinski square slots in the radiating decagonalshaped monopole, and UWB operations are accomplished by utilizing double truncations in the ground plane.…”

In this paper, miniaturization of fractal geometry with defected ground structure (DGC) concept has been experimentally verified at S-band (2–4) GHz. The design starts with a self-symmetry structure using conventional Vicsek snowflake-box fractal antenna. The same has been used in third iteration to achieve miniaturization. This proposed microstrip patch antenna (MPA) is resonating at 2.12 GHz with acceptable gain and broadside radiation. The miniaturization of about 87.26% when compared to conventional fractal MPA is achieved. The fractal unit cell is optimized for miniaturization and bandwidth by carrying out parametric study and applying the DGS shapes like rectangular and U-shaped slot etched in the ground plane of Vicsek snowflake-box fractal microstrip antenna. A fractal microstrip antenna is designed for wireless applications at 3.95 GHz. The fractal microstrip antenna is simulated using HFSS-V15 simulator. It is observed that the maximum size reduction of 87.26% is achieved in the third iteration of the Vicsek snowflake-box fractal radiating patch. The proposed fractal patch antenna is designed and fabricated using epoxy substrate of FR-4 with dielectric constant of 4.4 and thickness of 1.6 mm. The simulated results are compared with the measured results.

The Sierpinski gasket fractal concept is used on a microstrip antenna in this paper. A self-similar property of fractal geometry is used, which is based on an iteration algorithm that reaches up to third iterations. It is simulated using the HFSS (High-Frequency Structure Simulator) software package version.15. A designed antenna is used to improve antenna performance, such as increasing bandwidth to 980 MHz and reducing the return loss from − 31.97 to − 23.4 dB. To excite the proposed antenna, a microstrip line feed is used. Up to 27% fractional bandwidth has been achieved in the antenna. This antenna can be used for a variety of wireless applications, including Marine radar and some communication satellites such as (Wireless LAN, Bluetooth, microwave devices/communications, and cell phone), as well as the lower portion of C-band.

The paper proposes the use of MATLAB simulations as a first step in identifying proper antennas to be used in specific ultra-high frequency (UHF) communication links. Giving that fractal antennas provide interesting features, we aimed at comparing a few of their significant parameters with those of a monopole antenna so as to ensure signal coverage between two real sites situated at 5.82 km distance in a mixture of urban and flat – open terrain conditions. We started from the requirements imposed to the return loss of the antenna and to the link margin, we established their desired thresholds and then computed solutions regarding which antenna type in the set provide the highest received power and on which frequency sub-bands can be successfully used. The studied fractal antenna set were from the series Koch, Koch loop and Sierpinski. The chosen radio link refers to a real situation on the map. Generally, different narrow bands were provided by each antenna regardless of its type, but still, comparing them with the monopole, better solutions could be identified.
