Mobile device with two antennas and antenna switch modules

摘要

A mobile device includes a system circuit board, a ground element, a communication module, a first antenna, a second antenna, a first ASM (Antenna Switch Module), and a second ASM. The first antenna is configured to receive or transmit a first signal in a first frequency band. The second antenna is configured to receive or transmit a second signal in a second frequency band. The second frequency band is different from the first frequency band. The first ASM is coupled between the first antenna and the communication module, and is configured to separate frequencies of the first signal. The second ASM is coupled between the second antenna and the communication module, and is configured to separate frequencies of the second signal.

1. A mobile device, comprising:
a system circuit board; a ground element, disposed on the system circuit board; a communication module; a first antenna, configured to receive or transmit a first signal in a first frequency band; a second antenna, configured to receive or transmit a second signal in a second frequency band, wherein the second frequency band is different from the first frequency band; a first ASM (Antenna Switch Module), coupled between the communication module and the first antenna, and configured to separate frequencies of the first signal; and a second ASM, coupled between the communication module and the second antenna, and configured to separate frequencies of the second signal, wherein the first antenna has a first projection on the system circuit board, and the second antenna has a second projection on the system circuit board, and neither the first projection nor the second projection overlaps with the ground element; wherein the first antenna comprises: a first feeding element, coupled through the first ASM to the communication module; a first radiation element, separated from the first feeding element, wherein one end of the first radiation element is coupled to the ground element, and a first coupling gap is formed between the other end of the first radiation element and the first feeding element; and a first extension element, coupled to the first radiation element.
