Abstract
One embodiment discloses an antenna structure. The antenna structure may comprise a transmit antenna element comprising a first transmit antenna sub-element and a second transmit antenna sub-element. The antenna structure can comprise a receive antenna element comprising a first receive antenna sub-element and a second receive antenna sub-element. At least one electronic component of the antenna structure may be coupled with a ground plane. The first transmit antenna sub-element, the second transmit antenna sub-element, the first receive antenna sub-element, and the second receive antenna sub-element may each comprise a first portion and a second portion. The second portion may be larger than the first portion. The first portion can be closer to a center position of an arrangement of the sub-elements than the second portion. In one embodiment, the arrangement of the sub-elements about the center position forms a four-leaf clover-like arrangement.
