Abstract: An antenna structure includes a ground element and a metal loop. The metal loop includes a main radiation element and a float radiation element. The main radiation element has a feeding point, a first shorting point, and a second shorting point. The first shorting point and the second shorting point are both coupled to the ground element. The feeding point is substantially positioned between the first shorting point and the second shorting point. The float radiation element is adjacent to the main radiation element, and is separated from the ground element and the main radiation element. The ground element is substantially surrounded by the metal loop.

Abstract: A method of producing a string of multiple cleansing net packages for cleaning and massaging the back of a person taking a bath includes the steps of mounting looped net packages of even or odd numbers onto a U-shaped bracket; and tying a pull loop to the middle of the front portions of the top and the bottom looped net packages; turning the top or/and the bottom looped net packages half turn around clockwisely, depending on the net packages being of an even or odd number; and then binding the middles of the front portions of every two consecutive looped net packages together exclusively and so on so forth, starting from the top or the second looped net packages; and then binding the middles of the rear portions of every two consecutive looped net packages exclusively together and so on so forth, starting from the top or the second looped net package, depending on the looped net packages being of an even or odd number; and then turning clockwisely all the looped net packages on the bracket 1/4 turn around; af
