Proximity coupling technique is applied to feed each patch through a microstrip line to improve the radiation pattern of array antenna. The feature of switchable polarization is achieved using a uniform arrangement of switch-controlled patch by alternately grounding unused patches into the groundplane. The array configuration is designed on 2 layers of FR4 epoxy dielectric substrate with 1.6 mm thickness of each layer. The characterization result proves the polarization switchability of array antenna in eight directions with 45° steps in the azimuth plane. The -10 dB working bandwidth of array antenna with the center frequency of 2.35 GHz is 142 MHz ranges from the frequency of 2.281 GHz-2.423 GHz with gain achievement of 2.01 dBi at its center frequency.[/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]Arrangement of switches,Array configurations,Dielectric substrates,Proximity coupled patches,Proximity couplings,Switchable polarization,Wireless local area network applications,WLAN applications[/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][/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]This work is partially supported by the postgraduate team research program (Penelitian Tim Pasca Sarjana) from the Ministry of Research, Technology and Higher Education, the Republic of Indonesia FY2017-FY2018.
