1. An apparatus comprising:
a first switch configured to switch between a first radio frequency (RF) input and a first impedance termination; a second switch configured to switch between a second RF input and a second impedance termination; a first antenna disposed on an antenna carrier of a user device and coupled to the first switch, wherein the first antenna is configured to communicate first data in a first plurality of frequency bands and to transmit second data in an additional frequency band when the first switch is coupled to the first RF input; and a second antenna disposed on the antenna carrier of the user device and coupled to the second switch, wherein the second antenna is configured to communicate third data in a second plurality of frequency bands and to receive fourth data in the additional frequency band when the second switch is coupled to the second RF input, wherein the first antenna is configured to communicate the first data in three frequency bands of the first plurality of frequency bands and to transmit the second data in a fourth frequency band as the additional frequency band, and wherein the second antenna is configured to communicate the third data in fifth and sixth frequency bands of the second plurality of frequency bands and to receive the fourth data in the fourth frequency band, wherein the first antenna, operating in the three frequency bands, covers a range of frequencies between 824 MHz to 960 MHz and between 747 MHz to 787 MHz in a low band, wherein the first antenna, operating in the fourth frequency band, covers a first range of frequencies between 1710 MHz to 1755 MHz in a high band, and wherein the second antenna, operating in the fourth frequency band, covers a second range of frequencies between 2110 MHz to 2155 MHz in the high band.
