Abstract

A device includes a plurality of antennas, including one or more active antennas, the antennas being configured in one of a plurality of possible configurations to achieve operation in WAN, LTE, WiFi, or WiMax bands, or a combination thereof. In some embodiments, a passive antenna is utilized with lumped loading to fix the antenna tuning state. A primary and auxiliary radiator can be included in the device and configured for WAN/LTE bands, while additional antennas can be incorporated for WiFi and WiMax bands. Various antenna configurations incorporate the antenna having multiple coupled regions.

First claim

We claim:

1. An antenna system, the antenna system comprising:
a first antenna and a second antenna,
the first antenna comprising:
a first antenna radiating element positioned above a first ground plane,
the first antenna radiating element comprising a bent conductor forming an inductive loop region and a capacitive overlapping region setting up a magnetic dipole mode;
a first parasitic element positioned above the first ground plane and adjacent to the first antenna radiating element, and
a plurality of first components coupled to the first parasitic element and further coupled to the first ground plane,
wherein each component of the plurality of first components is one of: a capacitor, inductor, or resistor;

the second antenna comprising:
a second antenna radiating element positioned above a second ground plane,
the second antenna radiating element comprising a bent conductor forming an inductive loop region and a capacitive overlapping region setting up a magnetic dipole mode;
a second parasitic element positioned above the second ground plane and adjacent to the second antenna radiating element, and
a plurality of second components coupled to the second parasitic element and further coupled to the second ground plane,
wherein each component of the plurality of second components is one of: a capacitor, inductor, or resistor.

2. The antenna system of claim 1 , the antenna system comprising three or more antennas.

3. The antenna system of claim 1 , said plurality of first components comprising at least one capacitor, at least one inductor, and at least one resistor.

4. The antenna system of claim 1 , wherein the first antenna is fabricated on a planar substrate.

5. The antenna system of claim 1 , wherein one or more of the plurality of first components comprises an active tunable component, wherein a reactance associated with the active tunable component is adjustable.

6. The antenna system of claim 5 , wherein the first antenna is an active tunable antenna.

7. The antenna system of claim 1 , the first antenna further comprising a first switch coupled to one or more of the plurality of first components, the first switch being configured to select or de-select each of the one or more of the plurality of first components coupled therewith.

8. The antenna system of claim 7 , wherein the first antenna is an active tunable antenna.

9. The antenna system of claim 1 , at least one of the first and second antennas comprising two or more parasitic elements each being positioned above the ground plane and adjacent to the antenna radiating element.

10. The antenna system of claim 1 , wherein each of the first and second antennas is individually configured as: an active tunable antenna having an adjustable radiation pattern mode, or a passive antenna having a fixed radiation pattern mode.

11. The antenna system of claim 10 , the first and second antennas being configured in a multi-input mufti-output (MIMO) array.

12. The antenna system of claim 1 , wherein the first antenna forms a primary antenna configured for WAN/LTE communication, and the second antenna is configured for one of: WAN/LTE, WiFi, or WiMax communication.
