| Abstract: A loop antenna is described herein that is suitable for operation in free
space or in proximity to a ground plane. The loop antenna comprises a
looped conductive element with a gap formed therein and a tab extending
toward the gap. A length of the tab of the loop antenna is selected such
that a detuning loss of the loop antenna from operation in free space to
operation in proximity to a ground plane is low. In an exemplary
embodiment, the length of the tab is selected such that a reactance of
the loop antenna in free space is within a threshold level of a reactance
of the loop antenna when the antenna is in proximity to a ground plane. |
