“…However, if the parameter setting is not reasonable, the optimal solution cannot be obtained. Compared with the traditional optimization method, this algorithm is characterized by high accuracy, high efficiency, and high flexibility [ 41 ]. Therefore, the GA is the best choice to obtain the optimal solution for the sole objective.…”

5G mmWave broadcasting is considered to be the main method of future broadcasting. However, the mmWave transmission has a large space loss, especially in tunnels. In order to compensate for the attenuation of the broadcast signal, a directional horn antenna is designed in this paper. Substrate integrated waveguide (SIW) technology, dual-element arrays and extension structures are used to improve the antenna structure and achieve good directional characteristics. The multi-objective genetic algorithm (MOGA) is used to optimize the antenna parameters and improve optimization efficiency. Ultimately, the whole antenna was 28.2 mm in length and 28.6 mm in width, and the FR4 material, with a relative permittivity of 4.4, was used as a dielectric plate. The maximum gain of the antenna is 8.06 dB, and the bandwidth with gain greater than 6.5 dB is nearly 2 GHz. Antenna performance simulation and test results show that the extended semicircular structure is beneficial in enhancing the directional radiation of the antenna. This provides a reference method for directional antennas applied to 5G millimeter wave bands to increase gain and narrow beams.

“…A multiple band frequency antenna is proposed with the elliptical and fractal structure in [6] which not the UWB antenna. Various algorithms, structures, methods to improve the antenna performance are proposed and discussed in [7][8][9][10][11][12][13][14] all are having modification in the patch. One of the simple approaches is etching the ground can give ultra-wideband operation without altering the parch shape.…”

Now a day the requirement of wireless communication increased rapidly with the demand for applications. This leads to the requirement of the design of compact wireless transceiver units. The antenna is one of the major blocks in the design which defines the compactness and efficiency of the unit. In this work, an elliptical patch antenna is designed on the FR4 substrate with εr= 4.2. Again the effect of etching the ground is studied. Also, the effect of inset feeding length studied. In the work, the author discussed various methods to convert a narrow band (NB) antenna into the ultra-wideband (UWB) antenna and wise versa. The proposed antenna can work in ultra band operation from 1 GHz to 12GHz. The same proposed structure can work a wide band of 5.8 GHz bandwidth from 2 GHz to 7.8 GHz with inset feed.
