In the case of a lumped gap port on a rectangle, this self inductance can be de-embedded, as the current and its H-field can be calculated on the port solution. The same is valid for circuit ports: they connect the conductor point with the return path point , inject a current, therefore have a H-field and a self inductance, but this can not be de-embedded as the self inductance of a circuit port can not be calculated. that&#8217;s why the recommendation is to keep it shorter than lambda\/20, what is issued as a warning by the solver, if the circuit port is too long, because than the self inductance which is part of the results could influence the result in a non tolerable way.<\/p>\n","protected":false},"template":"","class_list":["post-164286","topic","type-topic","status-publish","hentry","topic-tag-17-2","topic-tag-electromagnetics-electronics","topic-tag-excitations","topic-tag-hfss","topic-tag-lumped-port"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["1-24-2023  20:20:11"],"_bbp_forum_id":["27819"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["1155"],"siebel_km_number":["2043803"],"product_version":["17.2"],"km_published_date":["2016-10-11T13:19:09.000Z"],"family":["Electromagnetics & Electronics"],"application_name":["HFSS"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164286","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164286\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164286"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
