“…The small deviation between the simulated and measured gain value was due to the presence of electrical wires; moreover, the practical model diode also affected the performance since lumped ports were used in the simulations. The presented antenna design can further be investigated for arrays and MIMO configurations [39][40][41][42].…”

A simple and compact antenna with a switchable beam for millimeter-wave communication is proposed in this paper. The antenna has a planar structure, and the design evolution is discussed. The beam switching functionality was achieved by incorporating two PIN diodes in the ground plane of the antenna. By switching ON either of the PIN diodes, the inverted L-shaped stub becomes connected to the ground plane and behaves as a cavity, which causes the dispersion of the radiation pattern. Therefore, a wide-angle (±18∘) beam-switching property can be achieved using a simple and low-cost technique, without the necessity to implement additional conventional circuits. The proposed antenna is characterized by a good performance in terms of return loss, bandwidth, measured gain up to 7.95 dB, and radiation efficiency up to 84%, making it a proper candidate for IoT technology and millimeter-wave 5G devices.

“…These sections allow for frequency changes from 28 to 24.8 GHz with gains of 16.02 and 15.07 dB, as well as a bandwidth of 2.1 and 1.9 GHz, respectively. Zahra et al [19] presented the design of a free planar single-hole helical antenna for broadband applications at 28 GHz. This antenna provides a wide impedance bandwidth from 26.25 to 30.14 GHz, gain measured up to 5.83 dB, and radiation efficiency measured up to 85%.…”

<span lang="EN-US">This paper presents a study and an array design consisting of two microstrip patch antennas connected in series in a 2×1 form. This antenna provides better performance for the fifth-generation (5G) wireless communication system. The microstrip line feeding technique realizes the design of this antenna. This feed offers the best bandwidth, is easy to model, and has low spurious radiation. The distance between the feed line and the patch can adapt to the antenna’s impedance. In addition, the antenna array proposed in this paper is designed and simulated using the high frequency structure simulator (HFSS) simulation software at the operating frequency of 28 GHz for the 5G band. The support material used is Rogers RT/duroid® 5880, with relative permittivity of 2.2, a thickness of h=0.5 mm, and a loss tangent of 0.0009. The simulation results obtained in this research paper are as: reflection coefficient: -35.91 dB, standing wave ratio (SWR): 1.032, bandwidth: 1.43 GHz, gain: 9.42 dB, directivity: 9.47 dB, radiated power: 29.94 dBm, accepted the power: 29.99 dBm, radiation efficiency: 29.95, efficiency: 99.83%. This proposed antenna array has achieved better performance than other antenna arrays recently published in scientific journals regarding bandwidth, beam gain, reflection coefficient, SWR, radiated power, accepted power, and efficiency. Therefore, this antenna array will likely become an important competitor for many uses within the 5G wireless applications.</span>

“…In practical communication applications [4], the phased array antennas should have characteristics such as broadband, circular polarization, and wide angular domain scanning. Thus, the circular polarized antennas are well suited to address the challenges associated with the mobility, severe weather conditions, and non-line-of-sight applications [5,6]. However, as the scanning angle of the main beam increases, the beam gain decreases sharply and other factors lead to the deterioration of the active reflection coefficient and other far-field performance such as the axis ratio.…”

As an important part of phased array system, the research on phased array antenna is very necessary. The phased array antenna achieves the scanning beam adaptively by regulating the phase difference between each array element. In this paper, a dual K-band circularly polarized antenna with high broadband, broadband beam, wide axial ratio bandwidth and high radiation efficiency is designed. We combine with the advantages of slot antenna and aperture antenna, use multimode waveguide cavity structure to design an aperture antenna, which is fed to waveguide circular polarizer by slot coupling in order to realize circular polarization radiation. Meanwhile, it has the characteristics of broadband, broadband beam, wide axial ratio bandwidth and high radiation efficiency. A slit antenna is designed by using a multimode waveguide cavity structure and a slit coupling feed to a waveguide circular polarizer is used to achieve circularly polarized radiation. The designed antenna consists of two K-band circularly polarized antenna units, and the spacing between the two units is 9.5 mm, which is fed by a K-band T/R module (Transmitter/Receiver module). In order to study the performance of the pattern in the case of the research group, the 2-unit structure is established. The simulation results of frequency-axial ratio bandwidth are given, and the simulation result of the antenna array is shown. The practical results of antenna design and test are also given.
