“…The table shows that in spite of the antenna compact size, it makes good balance between the BW, ARBW, and gain as well as its perfect coverage for the 5G mid-band standards. Additional single element CP antennas [27][28][29][30] are also listed in the below table. It is worth to mention that some of the references used in the comparison are MIMO antennas.…”

This study presents a compact broadband wide-slot antenna with broadband left-hand circular polarization compatible with both LTE 42 and LTE 43 standards of 5G mid-band applications. The proposed antenna is fabricated on an FR4 dielectric substrate with overall dimensions of 0.41𝜆 𝑜 × 0.36𝜆 𝑜 × 0.02𝜆 𝑜 , where 𝜆 𝑜 is the free space wavelength at the resonant frequency of the antenna. The antenna ground plane is etched to form a square radiating slot with a pair of rectangular ground stubs that are diagonally placed inside the slot. On the other side of the antenna, the feed line is loaded by horizontal and vertical stubs to improve the coupling between the feed line and the square slot. To generate a circular polarization, the feeding stubs cooperate with the pair of rectangular ground stubs to excite the radiating slot of the antenna at two different feeding points whose currents have approximately equal amplitude and 90 o phase shift. The measured impedance bandwidth (BW) of the proposed wide-slot antenna is 16.2% (580 MHz along the band 3.3-3.88 GHz), while the observed axial ratio bandwidth (ARBW) is 12.2% (440 MHz in the 3.4-3.84 GHz band). The measured gain values are found to be larger than 2.5 dB along both standards of the 5G mid-band applications.INDEX TERMS Axial Ratio, circular polarization, wide-slot antenna, reflection coefficient, broadband.

“…However, they interact with the radiating part to increase the antenna power [30]. When parasitic elements are exposed to the radiated field generated by the patch antenna, they become excited and generate currents [31]. These induced currents have a mutual counteracting effect on each other, which helps reduce cross-coupling effects.…”

This paper presents a novel, compact, and high gain metasurface (MS) patch antenna. The antenna structure consists of a slotted square patch in a fractal shape, integrated with a metasurface layer stacked on Taconic RF-30 dielectric material. The individual cells are arranged periodically, creating a 5 x 5-layer configuration. The proposed antenna is designed with physical dimensions of 290 x 290 mm² and achieves a maximum gain of 13.3 dBi at a frequency of 2.2 GHz. Moreover, it achieves a satisfactory minimum reflection coefficient of -10.9 dB. The design process and analysis were performed using the CST MWS simulation software. Based on the performance results obtained from this study, the suggested antenna can be considered suitable for applications in 5G communication.
