1. An apparatus for detection of electromagnetic tags of surgical articles in an operating room, the apparatus comprising:
a housing comprising a handle configured to be grasped by a user; and
an antenna assembly coupled to the housing and comprising a loop assembly, wherein the loop assembly comprises a conductor and a structural member, wherein the antenna assembly is configured to move from a collapsed configuration to a deployed configuration in which the antenna assembly forms an antenna loop configured to detect the electromagnetic tags; and
a tuning board coupled to the conductor and configured to generate a detection field to match a frequency range of the electromagnetic tags of the surgical articles, wherein the structural member comprises a first end and a second end each coupled to the tuning board; and
connectors coupling the first and second ends to the tuning board, wherein the connectors each comprise angled clamping surfaces configured to bias the structural member.
