Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is a dual-frequency linear antenna (1) developed using the J-shaped antenna and array antenna concepts for dual-band wireless communication, especially a wireless communication system Linear array of linear dipole antennas. [Previous technology] With the rapid popularization of portable electrical equipment in recent years, the development of wireless communication technology can be described as a thousand miles, and wireless communication equipment often must use two frequency bands to receive and transmit signals, such as the recently popular wireless Wireless local area network (WLAN) equipment. The communication frequency between its access point (AP) and wireless network card (WLAN Card) is used in accordance with the specifications of IEEE 802.11a, b, and g. In the wide-band field, two frequency bands, such as 2. 4 to 2. 5 GHz and 4. 9 to 5. 8 GHz, must be used. Therefore, in a dual-band wireless device, it is necessary to effectively use a dual-band antenna to obtain the maximum use benefit. In the aforementioned wireless local area network, in order to achieve miniaturization and aesthetics, wireless network cards mostly use internal antennas, while base stations use external antennas (with 1: ^) to avoid such concerns. 11 & 13111 ^ 111 ^). The dual-frequency antenna used by a conventional base station is shown in the first figure, which is mainly formed by laying a linear copper foil (A1) on a printed circuit board (A) to form a radiating β body to form a planar antenna. Function, but this kind of flat plate = line has a higher directivity in the transmission and reception of radio waves, that is, the fan-shaped area surrounded by the two sides of the board's orthogonal line, the better the transmission and reception effect, the more the board The extension surface (that is, parallel to the board surface) becomes worse, and M245604 V. Creation Instructions (2) The back of the circuit board without steel foil will also be blocked by the board, and the radio wave capacity will be affected. There are also two types of planar antennas that are used to glue together the body, or to use double-sided printing to lay copper foils on both sides of the board surface, which forms two antennas and planar antennas, so as to greatly improve the transmission and reception effect. It is still not enough to cover the full range of 360 degrees, because it still does not help the radiation effect in the area parallel to the board surface, that is, there is still a dead angle for radio wave transmission and reception. [New main line (-fruit, sequence. It is a quad-band type content in a first-class body] The main purpose of the creation is to provide an array-type dual-frequency linear antenna.) 'It has no omnidirectional radio wave transmission and reception effect. Dead angle, and the cost is extremely low, and no complicated manufacturing process is needed to achieve the above purpose. This creation is a radiator composed of four rigid linear conductors. The four-lead system is arranged at four corners in parallel and equidistant, and the four-lead has three conductors. It is about equal, which means that the high-frequency radio wave that is sent and received is about = wavelength, and the length of the other conductor is longer, which is about a quarter of the wavelength of the low-frequency wave that is sent and received. [Embodiment] See the second and third pictures of the body, which is the first example of the creation of this work. The quality of the embodiment shows the view. 'The light body of this creation (1) is made of four hard 12 Straight = shaped conductor (11, 12, 13, 14), the four conductors (11, see square ^ 14) are bare wires without insulation, the cross section is about 0.5 mm square, and Arranged in parallel at four equal distances
