“…In [4][5][6][7][8][9][10] dipole antenna arrays are identified. For operating frequencies up to 6 GHz, planar structures with several dipoles printed on a dielectric substrate are proposed [4][5][6], typically with one of the dipole arms printed on the top of dielectric surface and the other on the bottom. Variants of this structure, allowing greater bandwidth and operating up to 18 GHz, are proposed in [7,8].…”

Modern communication systems require high bandwidth to meet the needs of the huge number of sensors and the growing amount of data consumed, and an exponential growth is expected in the future with the integration of internet of things networks. Spectrum regions in the millimeter waves have aroused new interests, mainly because of the contiguous bands available to meet these needs. In return, and to combat the high losses of propagation in these frequencies, higher gain antennas are needed. This paper describes the use of a logarithmic architecture in the design of microstrip antenna arrays, creating structures with high gain and ultra-wide bandwidth. Three different solutions are presented with five, seven, and nine elements, reaching about 25%, 30%, and 44% of bandwidth, achieving ultra-wideband behavior, efficient and with a compact structure operating at frequencies in around 28 GHz.

“…A toothed bow tie‐shaped slot with two arms log‐periodic substrate integrated wave guide antenna is proposed at 28 GHz but in this article, there is no fabricated prototype is shown and corresponding measured results also were not discussed 13 . A printed LPDA antenna for 3.4 to 3.8 GHz is designed, simulated, and compared with measured results are also performed but in this article lower end of millimeter‐wave frequency bands are considered and the gain attained is also very less 14 . A 10 dipole log periodic antenna which is capable of rejecting 4G‐LTE mobile services is designed and simulated at the frequency band ranging from 450 to 1000 MHz whichever is not suitable for the millimeter‐wave frequency band but the concept of carrel's model can be considered from this article 15 .…”

A wide band log periodic millimeter‐wave antenna is proposed for 5G femtocells applications. This log periodic antenna consists of circular patches with radius kept up at a proportion of scaling factor τ=1.05. The proposed antenna prototype is designed and simulated at a frequency range of 25 to 35.5 GHz with a fractional bandwidth of 34.73%. This proposed antenna exhibits low return loss at all frequency bands such as 26, 27.5, 29, 30, 32, 33, 35, and 38.1 GHz with reflection coefficient values such as −13.41,−29.07,−30.9,−23.11,−11.29,−11.44,−12.47, and −10.01 dB including almost 101% radiation efficiency and attained maximum gain values such as 11.36,10.86,10.83,11.31,9.88,9.19,11.5, and 12.36 dBi. Over the entire frequency band, the proposed antenna exhibits right‐hand circular polarization with an axial ratio of under 3 dB. Furthermore, the antenna is fabricated and measured the results where there is a better agreement with simulated results. This type of low‐profile antenna can be applicable for femto base stations for 5G communications.

This paper implies a prototype for a broad-band log periodic dipole antenna (LPDA) with dimensions of 20 × 40 × 0.508 mm3 equipped with directors. The LPDA is based on Roger’s RT5880 with εr = 2.2. The 4-arms with alternative stubs constitute the LPDA, which is evenly spaced on both lines. At the substrate’s back, the 50Ω main feeder line is placed on partial ground. The directors are also incorporated and studied in a regular matrix at a predetermined distance to improve gain, further reduce side lobes, and widen the frequency band. The performance of the antenna covers a wide spectrum of millimeter waves ranging from 26 up to 44 GHz. The realized gain for the antenna is 8.97, 11.96, 13.96, and 14.29 dB at 28 GHz, 35 GHz, 38 GHz, and 43 GHz, respectively. The total gain is 14.29 dB as a peak gain. The antenna was designed and tested for 5G communication applications in autonomous vehicles, and the design cost for the antenna is low in comparison to dielectric lenses. The model exhibits symmetrical radiation patterns for the antenna range. The results of the simulations and the testing of the implemented antenna elements coincide quite well. The proposed design outperforms earlier work in this field.
