Abstract: A broadband transceiver includes at least one layer structure that is substantially impermeable to RF radiation. The layer structure includes a first face surface substantially opposite a second face surface. A receive antenna is located proximate the first face surface and configured to receive RF transmissions. A transmit antenna is located proximate the second surface and configured to transmit RF transmissions. At least one of the receive and transmit antennas generates a generally toroidal radiation pattern that is stronger in a direction substantially parallel to the respective layer structure face surface compared to a direction substantially perpendicular to the face surface.

Abstract: One embodiment discloses an antenna structure. An antenna structure comprises: a ground plane; a transmit balanced to unbalanced (BALUN) circuit comprising a first transmit connector coupled to a combined transmit port, and a second transmit connector coupled to the combined transit port; a receive BALUN circuit comprising a first receive connector coupled to a combined receive port, and a second receive connector coupled to the combined receive port; a transmit antenna element comprising a first transmit antenna sub-element coupled to the first transmit connector and a second transmit antenna sub-element coupled to the second transmit connector; a receive antenna element independent from the transmit antenna element and comprising a first receive antenna sub-element coupled to the first receive connector and a second receive antenna sub-element coupled to the second receive connector, wherein the transmit antenna element and the receive antenna element are orthogonally-polarized with respect to each other.

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.
