Because the helical antenna will be soldered to the pcb. Please help.&lt;\/div&gt;&lt;p&gt;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Especially when extracting the S11 parameters from the IC feed point, I need to define in the program that the copper helical antenna touches the PCB from the through hole point.<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/10-11-2024-1731253307-mceclip1.png\" \/>&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-393472","topic","type-topic","status-publish","hentry","topic-tag-helicalantenna-1","topic-tag-hfss"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["212.125.26.84"],"_btv_view_count":["561"],"_bbp_topic_status":["unanswered"],"_edit_last":["283652"],"_bbp_revision_log":["a:1:{i:393474;a:2:{s:6:\"author\";i:283652;s:6:\"reason\";s:0:\"\";}}"],"_bbp_subscription":["17993"],"_bbp_topic_id":["393472"],"_bbp_forum_id":["27793"],"_bbp_engagement":["17993","283652"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["393509"],"_bbp_last_active_id":["393509"],"_bbp_last_active_time":["2024-11-11 03:40:00"]},"test":"kagankarakusxgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393472","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393472\/revisions"}],"predecessor-version":[{"id":393474,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393472\/revisions\/393474"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=393472"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
