Dual antenna device
A dual antenna device includes a first antenna of a first polarization, a second antenna of a second polarization, and a conducting wall. The first antenna includes a grounding unit, a first substrate positioned on the grounding unit, a first radiating unit positioned on the first substrate, and a first feeding unit coupled to the first radiating unit. The conducting wall is coupled to the grounding unit and the first radiating unit, and forms a space above the grounding unit. The second antenna includes a second radiating unit and a second feeding unit coupled to the second radiating unit and placed through the space.
1. A dual antenna device comprising:
a first antenna of a first polarization comprising:
a grounding unit;
a first substrate positioned on the grounding unit;
a first radiating unit positioned on the first substrate; and
a first feeding unit coupled to the first radiating unit;
a conducting wall coupled to the grounding unit and the first radiating unit for forming a space above the grounding unit; and
a second antenna of a second polarization comprising:
a second radiating unit; and
a second feeding unit coupled to the second radiating unit and placed through the space.
2. The dual antenna device of claim 1 , wherein the first polarization is opposite to the second polarization.
3. The dual antenna device of claim 1 , wherein the second antenna utilizes the first radiating unit as a ground.
