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.
Claims17
An antenna system, comprising:
- an multi-mode antenna comprising a radiating element and at least one parasitic element positioned proximate to the radiating element;
- an active tuning circuit integrated with a front-end module, the front-end module comprising:
- a switch configured to control a radiation mode of a plurality of radiation modes of the multi-mode antenna;
- and
- a transmit/receive (T/R) switch configured to couple the multi-mode antenna to a power amplifier (PA) and a low noise amplifier (LNA).
An antenna system, comprising:
- a multi-mode antenna comprising a radiating element and at least one parasitic element positioned proximate to the radiating element;
