Abstract

A 5G broadband antenna is disclosed herein. The 5G broadband antenna comprises a first antenna element and a second antenna element. Each of the first antenna element and the second antenna element has a main branch with a slot therein. The antenna apparatus covers a first frequency band of 617-960 MegaHertz, a second frequency band of 1.4-1.6 GigaHertz (GHZ), a third frequency band of 1.71-2.7 GHz, a fourth frequency band of 3.3 to 4.2 GHz, and a fifth frequency band of 4.3 to 6.0 GHz.

First claim

We claim as our invention:

1. A 5G broadband antenna apparatus, the antenna apparatus comprising:
a first antenna element comprising a first body with a first main branch having a first internal slot therein, a first mid-branch, and a first lower branch shorter in length than the first mid-branch and the first mid-branch between the first main branch and the first lower branch;
a second antenna element comprising a second body with a second main branch having a second internal slot therein, a second mid-branch, and a second lower branch shorter in length than the second mid-branch and the second mid-branch between the second main branch and the second lower branch;
wherein the antenna apparatus covers a first frequency band of 617-960 MegaHertz, a second frequency band of 1.4-1.6 GigaHertz (GHz), a third frequency band of 1.71-2.7 GHz, a fourth frequency band of 3.3 to 4.2 GHz, and a fifth frequency band of 4.3 to 6.0 GHz;
wherein the first lower branch and the second lower branch cover the high band bandwidth ranging 3.3 to 4.2 GHz and the high band bandwidth ranging 4.3 to 6.0 GHz.

2. The antenna apparatus according to claim 1 further comprising a base, wherein the first antenna element and the second antenna element are disposed on a surface of the base.

3. The antenna apparatus according to claim 2 further comprising a feed coaxial cable with an inner conductor connected to a feed point on the first antenna element and with an outer conductor connected to a grounding point on the second antenna element.

4. The antenna apparatus according to claim 1 wherein the antenna apparatus has a length ranging from 150 millimeters (mm) to 175 mm, and a width ranging from 25 mm to 40 mm.

5. The antenna apparatus according to claim 2 wherein the base is a PCB.

6. A 5G broadband antenna apparatus, the antenna apparatus comprising:
a base;
a first antenna element comprising a first body with a first main branch having a first internal slot therein, a first mid-branch, and a first lower branch shorter in length than the first mid-branch;
a second antenna element comprising a second body with a second main branch having a second internal slot therein, a second mid-branch, and a second lower branch shorter in length than the second mid-branch;
wherein the antenna apparatus covers a first frequency band of 617-960 MegaHertz, a second frequency band of 1.4-1.6 GigaHertz (GHZ), a third frequency band of 1.71-2.7 GHz, a fourth frequency band of 3.3 to 4.2 GHz, and a fifth frequency band of 4.3 to 6.0 GHz;
wherein the first lower branch and the second lower branch cover the high band bandwidth ranging 3.3 to 4.2 GHz and the high band bandwidth ranging 4.3 to 6.0 GHz.

7. The antenna apparatus according to claim 6 wherein the first main branch and the second main branch cover the low band bandwidth ranging 617 MHz to 960 MHz.

8. The antenna apparatus according to claim 6 wherein the antenna apparatus has a length ranging from 150 millimeters (mm) to 175 mm, and a width ranging from 25 mm to 40 mm.

9. The antenna apparatus according to claim 6 further comprising a feed coaxial cable with an inner conductor connected to a feed point on the first antenna element and with an outer conductor connected to a grounding point on the second antenna element.

10. The antenna apparatus according to claim 6 wherein the first main branch has a first vertical section and the second main branch has a second vertical section.

11. The antenna apparatus according to claim 6 wherein the first mid-branch and the second mid-branch cover the wide bandwidth for the middle bands ranging 1.4 GHz to 1.6 GHz and 1.71 GHz to 2.7 GHz.
