Abstract
A technique is described where the switch and/or tunable control circuit for use with an active multi-mode antenna is positioned remote from the antenna structure itself for integration into host communication systems. Electrical delay and impedance characteristics are compensated for in the design and configuration of transmission lines or parasitic elements as the active multi-mode antenna structure is positioned in optimal locations such that significant electrical delay is introduced between the RF front-end circuit and multi-mode antenna. This technique can be implemented in designs where it is convenient to locate switches in a front-end module (FEM) and the FEM is located in vicinity to the transceiver.
Claims18
An antenna system, comprising:
- a ground plane;
- a first multi-mode antenna, comprising:
- a first radiating element spaced apart from the ground plane and defining a first antenna volume therebetween;
- a first parasitic element spaced apart from the ground plane, the first parasitic element positioned outside of the first antenna volume and adjacent to the first radiating element;
- and
- a first active tuning circuit integrated with a first front-end module;
- and
- a second multi-mode antenna, comprising:
- a second radiating element spaced apart from the ground plane and defining a second antenna volume therebetween;
- a second parasitic element spaced apart from the ground plane, the second parasitic element positioned outside of the second antenna volume and adjacent to the second radiating element;
- and
- a second active tuning circuit integrated with a second front-end module;
- the first front-end module and the second front-end module being associated with a communication system.
The antenna system of 15, wherein:
- the first transmission line comprises a single conductive trace;
- and
- the second transmission line comprises a single conductive trace or a plurality of traces.
