Antenna arrangement

摘要

The embodiments herein relate to an antenna arrangement comprising a ground element, and a first branch comprising a first inductor loading (L1) and a second inductor loading (L2). The antenna arrangement further comprises a second branch connected to the ground element via a feeding point, a third branch comprising a third inductor loading (L3) and a first grounding pin connected to the first branch. A first conductor loading (C1) is arranged between the first branch and the second branch. A second conductor loading (C2) is arranged between the second branch and the third branch. And the second branch is connected to the first branch via the first conductor loading (C1) and the second branch is connected to the third branch via the second conductor loading (C2).

主权项

1. An inductor capacitor (LC)-loading antenna arrangement comprising:
a ground element; a first branch comprising a first inductor loading and a second inductor loading; a second branch connected to the ground element via a feeding point; a third branch comprising a third inductor loading; and a first grounding pin connected to the first branch;wherein a first conductor loading is arranged between the first branch and the second branch and arranged to control coupling between the second branch and the first branch, and wherein the first conductor loading and the first inductor loading are connected in series;
wherein a second conductor loading is arranged between the second branch and the third branch and arranged to control the coupling between the second branch and the third branch, and wherein the second conductor loading and the third inductor loading are connected in series; wherein the second branch is connected to the first branch via the first conductor loading and the second branch is connected to the third branch via the second conductor loading, wherein the first conductor loading and the second inductor loading create a loop which excites a first high band resonance in the LC-loading antenna arrangement, wherein the second branch creates a second high band resonance in the LC-loading antenna arrangement, and wherein the third inductor loading creates a third high band resonance in the LC-loading antenna arrangement.
