Abstract:A low-profile wideband unidirectional dipole antenna is presented for the 5G operation. Parasitic strips are utilized for broadband impedance matching at a relatively small height of 4.9 mm (0.067λ 0 , where λ 0 is the free-space wavelength at the center frequency). The measured results show that an impedance bandwidth of 55.4% is realized, ranged from 2.96 GHz to 5.23 GHz. The proposed antenna is with the merits of stable and symmetric unidirectional radiation patterns, low back-lobes and an average antenna gain of 7 dBi over the operating band, making it very promising for 5G system.

“…More recently, electromagnetic band-gap (EBG) structures have been incorporated into the design to improve the performance of patch antennas. [5][6][7][8][9][10][11][12][13][14][15] As a kind of high impedance surface, the EBGs could be applied to suppress the propagation of the surface wave within the bandgap frequency range. 5,16 Accordingly, the configurations of the antennas do not need to be redesigned.…”

Generally, the surface wave of an antenna can be suppressed by integrating the electromagnetic band‐gap (EBG) structures. However, to achieve this effect, the EBG cells must be reasonably designed, otherwise it may lead to performance degradation instead. In this article, a dual‐band pinwheel‐shaped slot EBG structure is proposed. When applied to a patch antenna, defects are introduced into 3 rows of the EBG unit cells. The proposed antenna, incorporating EBGs designed with structural defects, to radiate at 4.9 and 5.4 GHz is simulated and tested. The measured results show that the −10‐dB bandwidth of the proposed EBG antenna is extended by 41% and 25.4% at low frequency and high frequency, respectively. In addition, the peak gain of the proposed EBG antenna is increased by 2.44 dB at 4.9 GHz and 2.86 dB at 5.4 GHz with >40% efficiency. When compared with the periodic EBG antenna, this antenna is more effective. Thus, these experimental results show that the performance of the EBG antenna can be improved by interrupting the periodicity of the EBGs structures.

Summary In this paper, a compact bend triangular resonator (CBTR) structure is proposed as artificial magnetic conductor (AMC) to enhance antenna gain for wide frequency bandwidth. This paper presents the metamaterial properties of the CBTR structure like absorbance and reflection phase. The CBTR unit cell gives in‐phase reflection (0° ± 90°) for 55.2% bandwidth. The CBTR unit‐cell reflection phase analysis is presented for the different height of normal incident wave. The CBTR AMC performance is validated using a wideband dipole antenna. For −6‐dB impedance bandwidth, the standalone dipole antenna covers ultrawide frequency range 3.1–12 GHz and for −10‐dB impedance bandwidth, antenna has dual band frequency response 3.4–4.4 GHz and 8.3–11 GHz. The antenna shows good impedance matching and radiation characteristics for frequency range, where the unit‐cell reflection phase is 135° to 45° for frequency range 2.5–6.5 GHz (bandwidth of 88.8%). The broadside directivity of 7 dBi is achieved for the dipole antenna with CBTR AMC in the frequency range of 2.5–6.5 GHz and broadside gain of >5 dBi in the frequency range of 3.2–6.7 GHz (bandwidth of 70.7%). The antenna efficiency of 60% (minimum) is achieved for the frequency range of 3.68.0 GHz (75.8%). The proposed CBTR design is orthogonally symmetric and is useful for dual‐polarized wideband frequency applications like wireless local area network (WLAN) (2.4–2.5 and 5.15–5.85 GHz) and new radio (NR) 5G sub‐6‐GHz (3.3–5.0 GHz).
