Multi-mode wideband antenna

摘要

Methods and systems for extending a bandwidth of a multi-mode wideband antenna of a user device are described. A multi-mode wideband antenna includes a single radio frequency (RF) feed coupled to a first element, and a second element coupled to the first element and a ground plane. The first element is to operate as a feeding structure to a parasitic grounding element that is coupled to the ground plane, but is not conductively connected to the RF feed. The multi-mode wideband antenna is configured to provide multiple resonant modes.

1. An electronic device comprising:
a single radio frequency (RF) feed; a ground plane; and a multi-mode monopole antenna coupled to the single RF feed, wherein the multi-mode monopole antenna comprises:
a first element conductively coupled to the single RF feed at a feeding point, wherein the first element comprises a first sub-element and a second sub-element;a second element conductively coupled to the ground plane at a first grounding point and conductively coupled to the first element at a distal point from the first grounding point, wherein the second element comprises:
a first arm coupled to the first grounding point;a middle portion coupled to a distal end of the first arm, the distal end being a farthest end of the first arm from the first grounding point, wherein the distal point is located at a first side of the middle portion; anda plurality of parallel traces that extend out from the middle portion at an opposite side from the first side where the first sub-element conductively connects to the first sub-element; anda first monopole element coupled to the ground plane at a second grounding point, wherein the second sub-element is a second monopole element and is disposed to form a first coupling section between the second monopole element and the first monopole element.
