In this paper, a compact dual-band Dolly-shaped antenna (DBDSA), resonating at 23.52 GHz and 28.39 GHz, is proposed for automotive radar, 5G, and Industrial, Scientific, and Medical (ISM) applications. The antenna is designed on a 7 Â 7 Â 1.28 mm 3 which is 0.541λ 0 Â0.541λ 0 Â0.099λ 0 in electric size, where λ 0 represents the free space wavelength at 23.16 GHz. Rogers RO3010 substrate with a dielectric constant of 10.2 and a loss tangent is about 0.0022 has been used. Two F-shaped parasitic elements and a rectangular slot have been used to achieve the desired electromagnetic antenna performances. After modeling and optimizing the proposed antenna configuration through High-Frequency Structure Simulator (HFSS) software, its prototype was manufactured and measured to validate the simulated results. The DBDSA achieves an overall radiation efficiency of 80% within the two operating frequency bands. The radar band exhibits a stable gain of 5.51 dBi, while the 5G band has a gain of 4.55 dBi. Furthermore, the experimental results show that the |S 11 | -10 dB bandwidths are 1.16 GHz (23.16 GHz-24.32 GHz) in the lower band and 634 MHz (28.078 GHz-28.712 GHz), respectively. A good agreement is found between the simulated and measured results.

“…The second approach is to operate simultaneously or consecutively different cavity or characteristics modes, and the last method is inserting multiple radiating elements [8], [12], [17]. Respectively, in the first approach, the primary purpose of including a parasitic element in the design leads to having the ability to control the beam where the direction of the steering is determined by the relative dimension and orientation of the parasitic elements [8]- [11]. Apart from the first approach, cavity modeling of the patch antenna types reveals the radiation mechanism of the antenna structure from a different perspective [12]- [15].…”

This study investigates a multi-mode pattern diverse microstrip patch antenna operating at 2.45 GHz. The study aims to have a flat top gain covering more than 900 in the elevation plane to provide equal service quality to everyone in the region of interest. In order to achieve such a crucial goal, the cavity model approach for the rectangular patches is employed. TM01 and TM02 modes are selected for the design since their corresponding radiation patterns are suitable for scanning a wide range. The superposition of boreside and conical (monopole-like) beams form a wide beam radiation pattern in elevation. Coupling between different modes is reduced by placing two radiators perpendicular to each other. In addition, the design aims to reduce both initial dimensions of the antenna by using fractalization, slotting, and perpendicular positioning techniques. These techniques reduce the original dimension of the design to less than its 60%. The simulation and experimental results reveal many similarities regarding the scattering parameters, radiation patterns, and gain. The scattering parameters, |S11| and |S22| at the operating frequency, are less than -10 dB, and the wide beam radiation pattern (more than 900) is obtained in the elevation plane.
