When I excite the antenna through a lumped port and I check the deembeing option box for lumped port, my reflection coefficient (S11) is well below -10 dB. But, when I leave the deembeding box unchecked, it violates -10 dB in some frequencies over this wide frequency range. Based on what I read in Ansys forum, removing inductance effect of a lumped port doesn&#8217;t have that much effect on the frequency response. However, in my case, I observe such a significant effect. Could you please guide me about this issue? Which response is reliable? Deembeding or undeembeding results?<\/p>\n<p>Kind regards,<\/p>\n<p>Nooshin<\/p>\n","protected":false},"template":"","class_list":["post-285861","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["72789","172290"],"_bbp_author_ip":["23.39.172.6"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1447"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["285861"],"_bbp_forum_id":["27793"],"_bbp_engagement":["72789","172290"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["286646"],"_bbp_last_active_id":["286646"],"_bbp_last_active_time":["2023-06-01 03:00:52"]},"test":"valizadnmcmaster-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/285861","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/285861\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=285861"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
