Antenna mast detection methods and systems
View Patent ↗An antenna is provided. The antenna includes an antenna base; and a detection mechanism removably coupled to the antenna base that generates a detection signal for detecting whether an antenna mast is coupled to the antenna base.
1. An antenna, comprising: an antenna base; and a detection mechanism that removably couples to the antenna base in place of an antenna mast, the detection mechanism configured to generate a detection signal for detecting whether the antenna mast is coupled to the antenna base.
2. The antenna of claim 1 , wherein the detection mechanism is a radio frequency (RF) device.
3. The antenna of claim 2 , wherein the RF device includes a plunger that is partially disposed within a plunger body, and that is movable within the plunger body between a first position and a second position.
4. The antenna of claim 3 , wherein the RF device further includes shunt mechanism that couples to the plunger body and to a ground element and that is movable with the plunger.
5. The antenna of claim 4 , wherein the ground element is of the antenna base.
6. The antenna of claim 5 , wherein the ground element of the antenna base couples to a vehicle chassis.
7. The antenna of claim 4 , wherein the shunt element creates a signal enable condition when the plunger is in the second position.
8. The antenna of claim 5 , wherein the RF device includes at least one of an electrical contact and an electrical line, and wherein the shunt element creates the signal enable condition when the shunt element is not in contact with the at least one of the electrical contact and the electrical line.
9. The antenna of claim 4 , wherein the shunt element creates a no signal condition when the plunger is in the first position.
10. The antenna of claim 9 , wherein the RF device includes at least one of an electrical contact and an electrical line, and wherein the shunt element creates the no signal condition when the shunt element is in contact with the at least one of the electrical contact and the electrical line.
11. The antenna of claim 1 , wherein the detection mechanism is integrated with a shipping cap.
12. The antenna of claim 1 , wherein the detection mechanism is separate from a shipping cap.
13. The antenna of claim 1 , wherein the antenna base couples to a vehicle.
14. The antenna of claim 1 , further comprising an infotainment system that receives the detection signal and that selectively detects whether the detection mechanism is installed to the antenna base based on the detection signal.
15. The antenna of claim 1 , wherein the detection signal is an amplitude modulation band signal.
16. The antenna of claim 1 , wherein the detection signal is a direct current power signal.
17. The antenna of claim 1 , wherein the detection signal is a voltage standing wave radio signal.
