1. A portable tracker device comprising:
a housing having a front cover and a back cover;
Radio Frequency (RF) circuitry configured to operate within at least one of a Bluetooth (BT) frequency range and an Ultra-Wideband (UWB) frequency range; and
a piezoelectric device having a first conductive plate and a second conductive plate;
wherein the RF circuitry utilizes at least one of the front cover, the back cover, the first conductive plate, and the second conductive plate as one or more antennas;
wherein the back cover of the housing includes a conductive material and is configured as a first antenna of the one or more antennas, and wherein the RF circuitry is configured to use the first antenna for BT communication; and
wherein the second conductive plate of the piezoelectric device is positioned adjacent to the front cover of the housing and is configured as a second antenna of the one or more antennas, and wherein the RF circuitry is further configured to use the second antenna for UWB communication.
