## Abstract

An antenna includes a controllable conductive material that is used to form transmit and/or receive antennas in different, controllable shapes. The controllable conductive material can be manipulated by an actuation control to form a continuous shape from one electrode to another to form the antenna. The controllable conductive material can be formed into multiple antennae each having a continuous shape extending between different electrodes. The antenna can be used for transmitting and receiving electromagnetic signals for determining the presence and/or amount of one or more analytes.

## Claims

### Claim 1

A non-invasive analyte sensor system comprising a controllable antenna configured to form a transmit shape and to form a receive shape, the controllable antenna configured to transmit a signal into a target using the transmit shape and to obtain a receive signal using the receive shape.

### Claim 2 (depends on 1)

The non-invasive analyte sensor system of claim 1, wherein the controllable antenna is configured to provide the transmit shape during a first period of time and the receive shape during a second period of time.

### Claim 3 (depends on 2)

The non-invasive analyte sensor system of claim 2, wherein the first period of time overlaps with the second period of time.

### Claim 4 (depends on 2)

The non-invasive analyte sensor system of claim 2, wherein the first period of time does not overlap with the second period of time.

### Claim 5 (depends on 4)

The non-invasive analyte sensor system of claim 4, wherein the second period of time begins when the first period of time ends.

### Claim 6 (depends on 1)

The non-invasive analyte sensor system of claim 1, wherein the controllable antenna is configured to switch between the transmit shape and the receive shape.
