The proposed antenna array consists of 8 elements with 8 ports in 2×4 square configuration. Dual-band characteristic was produced using slotted patch method. At these frequencies, we also compared the antenna gain between waveguide and SMA port feed techniques. It shows that the gain of antenna array with SMA port reaches 15.8 dBi at 28 GHz and 13.9 dBi at 38 GHz, respectively. There was a slight decrease of antenna gain with SMA port compared to that of the waveguide feed. All the 8 antenna-elements shows a very consistent return-loss (S11) characteristics, in that they have almost identical bandwidth to cover 28 GHz and 38 GHz. Also, each element has a very good isolation between each other, i.e the protection between their feeding point is more than 28.692 dB at 28 GHz and 38.779 dB for 38 GHz, which can meet the inter-element protection requirements.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antenna element,array,Dual Band,Fifth generation (5g),Millimeter-wave antennas,Protection requirements,Return losses (S11),slotted-patch[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antenna,array,dual-band,fifth generation (5G),millimeter-wave,slotted-patch[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/IWAT.2018.8379210[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
