APPARATUS AND METHODS FOR WIRELESS COMMUNICATION

摘要

An apparatus comprising: a first antenna having a first end configured to couple to a first port and a second end configured to couple to a second port, the first antenna extending between the first end and the second end and having a mid-point substantially halfway between the first end and the second end, the first antenna being configured to have a first electrical length and resonate in a first operational resonant frequency band; a second antenna extending from the first antenna at a position between one of the first end and the second end and the mid-point of the first antenna, the second antenna being configured to have a second electrical length and resonate in a second operational resonant frequency band; and a third antenna extending from the first antenna at position between one of the first end and the second end and the mid-point of the first antenna, the third antenna being configured to have a third electrical length and resonate in a third operational resonant frequency band.
