Abstract
An antenna arrangement including a first matching circuit; a second matching circuit; a first antenna connected to the first matching circuit; a second antenna, moveable with respect to the first antenna, between an extended position in which it is connected to the first matching circuit and a non-extended position in which it forms a couple between the first antenna and the second matching circuit, wherein the second antenna has an impedance that is brought towards a first impedance at a first operational frequency band when the second antenna is moved into the extended position and the first antenna has an impedance which is brought towards the first impedance at a first operational frequency band when the second antenna is moved into the non-extended position.
Claims15
An antenna arrangement comprising:
- a first matching circuit;
- a second matching circuit;
- a first antenna connected to the first matching circuit;
- a second antenna, moveable with respect to the first antenna, between an extended position in which it is connected to the first matching circuit and a non-extended position in which it forms a couple between the first antenna and the second matching circuit, wherein the second antenna has an impedance that is brought towards a first impedance at a first operational frequency band when the second antenna is moved into the extended position and the first antenna has an impedance which is brought towards the first impedance at a first operational frequency band when the second antenna is moved into the non-extended position.
An antenna arrangement as claimed in claim 10, wherein the whip antenna is telescopically moveable between the first position and the second position.
An antenna arrangement comprising:
- a first matching circuit;
- a first antenna connected to the first matching circuit
- a second matching circuit;
- a second antenna, moveable with respect to the first antenna, between an extended position and a non-extended position, and connectable to the second matching circuit when in the non-extended position, the first antenna being coupled to the second antenna when the second antenna is in the non-extended position, wherein the first antenna has an impedance which is brought towards a first impedance at a first operational frequency band when the second antenna is moved to the non-extended position and has an impedance which is shifted away from the first impedance when the second antenna is moved to the extended position.
An antenna arrangement comprising:
- a first matching circuit;
- a second matching circuit;
- a first antenna connected to the first matching circuit;
- and
- a second antenna, moveable between an extended position and a non-extended position, wherein the antenna arrangement has a first configuration in which the second antenna is extended and a second configuration in which the second antenna is retracted and wherein in the first configuration the first antenna and the second antenna are both connected to the first matching circuit and wherein in the second configuration the second antenna is disconnected from the first matching circuit and connected to the second matching circuit and the first antenna is connected to the first matching circuit and coupled to the second matching circuit via the second antenna.
