“…In addition, the planar structure further exhibited a wide band at a low gain of 2.8 dBi. Planar antenna such as Vivaldi antenna has been widely utilized in a range of application due to their low cross polarization, excessive directivity, and wide band characteristics . For instance, two adjacent Vivaldi taper slots excited by two ports generated end‐fire radiation along their slot direction with approximately ( α = 29°) between the two main beams to cover most of cellular and LTE bands.…”

A miniature broadband Vivaldi antenna with beam tilt characteristics suitable for lower 5G bands is presented in this article. This study is rationalized by adding two symmetric taper slots rotated 90° from the original single slot planar tapered antenna and by means of positive‐intrinsic‐negative diode as the switching component. The extended design with a cloverleaf shape is developed using computer simulation technology microwave studio and fabricated by integrating active MA4AGP907 diodes. The experimental results are validated using PNA network analyzer and an echoic chamber. A wide operating bandwidth (S11 ≤ |−10| dB) from 2 to 5 GHz is exhibited during the simulation of antenna performance as well as during the experimental process. Furthermore, the proposed design achieved beam tilt in three different orientations with the maximum at ϕ equals 0°; 90° and 180° in the XY coordinates at the peak gain of 5.19 dBi. An additional feature of the proposed design is the directivity control when two or three modes are switched simultaneously. With this beam tilt ability, the antenna can be used in the development of fifth generation communication systems where multibeam and directive beam are required.

“…The flaring angle decides the endfire pattern and subsequently, the endfire gain. Standard Vivaldi‐based designs usually incorporate a wideband balun, but the pattern integrity is deteriorated at higher end of the spectrum . Base station antennas usually operate with low insertion loss and high aperture efficiency mode.…”

In this article, a tapered slot antenna (TSA) operating from 27 to 29.8 GHz with an endfire gain of 9 dBi and high pattern integrity is presented. The gain specifications for path loss compensation on ground for a ceiling mounted millimeter wave base station is computed and the gain of the antenna elements with beam angled at ±45° was found to be 12 dBi. To enhance gain with minimal physical footprint, a combination of dielectric loading and electrical resonator metamaterial unit cells were integrated to the proposed TSA to achieve the expected gain enhancement of 3 dB across the band, operating in the same frequency band with aperture efficiency greater than 73% and a 1 dB gain bandwidth of 20.7%. A compact stacking topology for pattern diversity of all three antenna elements for path loss compensation is also investigated. The base station has a coverage of ±60° with uniform illumination and mutual coupling lesser than 35 dB. The detailed simulated and measured results are presented.

“…The 5G systems use mmWave, which has a problem with higher propagation loss than the conventional systems. For this reason, the antenna used in the 5G systems requires miniaturization, high gains, wide bandwidth, and high‐speed data transmission technology . Many studies have been done on antennas to satisfy these requirements.…”

This article presents a millimeter‐wave (mmWave) microstrip patch antenna (MPA) with a vertically coupled split ring metaplate (VCSRM). The narrow bandwidth and low gain of MPA are improved using VCSRM by periodically arranging split rings on the front and backsides of a dielectric slab. Numerical and experimental results show that the proposed antenna attains good radiation pattern, a high gain of 11.94 dBi, and a measured fractional bandwidth covering 26.58 to 29.31 GHz (9.77%). The gain of the antenna is increased by 5.35 dBi and the bandwidth is improved by 3.87% when compared to MPA without VCSRM. Thus, the proposed antenna with a small size of 18 × 22 mm2 is suitable for mmWave applications.
