“…Implementing the mmWave front-ends of the large antenna array may be complicated and expensive when the antenna array is excessively large. Thus, in order to meet the requirements of equivalent isotropic radiated power (EIRP) and reduce the system complexity, antenna elements can be combined to form a subarray [13]- [14], as shown in Fig. 1.…”

In this paper, millimeter wave (mmWave) filtenna arrays for 5G applications are proposed. Two kinds of 2-element subarrays are designed for horizontal and vertical polarizations. Each subarray consists of three substrate integrated waveguide (SIW) cavities and two sets of stacked patches. Fully-shielded combined eighth-mode SIW (FSD-CEMSIW) cavities are used in the filtenna design. This cavity not only works as the first-stage resonator but also as the power divider for the subarray. As a result, a four-order bandpass filtering response is achieved. Filtenna arrays were fabricated and measured for demonstration. The impedance bandwidths of these subarrays cover 24 -30 GHz, including the 5G mmWave bands (n257, n258, and n261) with measured average gains of 8.2 dBi and more than 22 dB out-of-band suppression. The proposed antennas can be good candidates for 5G mmWave communication to reduce the system complexity and potential cost of the mmWave front-ends.

Synthesizing antenna arrays for fifth-generation communication technology is the most significant issue in the electromagnetic industry and academia. This paper focused on a comprehensive algorithm to design an antenna array used as a 5G base station antenna. The proposed algorithm's goal has an array antenna with high gain, continuous wide scan angle without grating lobe, compact size, minimum cost, and simplicity of construction, particularly in the array feeding network's system. For this purpose, several factors, such as subarray topology, complex weighting function, the minimum number of RF elements, and the optimum number of microstrip layers will be intended. The desired topology is specified with the grating lobe's minimum level by comparing the array factor of different subarray combinations. We consider some limitations in our algorithm that improve the specification than before research and reduce the runtime algorithm. Moreover, the number of phase shifters is decreased to more than 53%, substantially improved than previous works. The GAPSO technique is then used to determine the excitation coefficients' optimal value to control SLL and beam scanning. Amplitude accuracy and phase are considered 0.1 and 1 degree, respectively, to avoid tolerance construction. The proposed method is also applied to design a linear array antenna using a 5G base station antenna in 28 GH. This aperiodic linear array's electromagnetic parameter consists of HPBW of 2.8◦, a gain of 20 dB, scanning up to ±50◦ in one direction, and SLL is below -15 dB.

“…For example, the datalink of Unmanned Aerial Vehicles (UAVs) requires the phased array to not only be compact in size, but also process at high performance levels to establish long distance network. In order to avoid the drawbacks of CMOS, some scholars have applied both GaAs and CMOS technology in array design [20]- [22], which significantly increases the complexity and cost of the array design. In this paper,…”

This paper presents a 36-element low-profile half-duplex K-band T/R phased array as a solution for the platform with limited aperture and space for the phased array. With the solution of micro-assembly presented in this paper, the height of the array is only 12.3 mm. To improve the phased array's performance in ultra-small aperture, multi-channel GaAs MMICs have been applied in this work. The array's scan angle could achieve ±50 • in both azimuth (H-plane) and elevation (E-plane). The EIRP and G/T of the array are 51dBm and-12.5dB/K respectively at the bandwidth from 21.5 GHz to 22 GHz.
