New Description: [New Technology Field] This creation is a folded dipole array antenna with wide frequency and high gain, especially a microstrip line and ground plane for designing the antenna in a limited substrate. Width to achieve impedance matching of the antenna, so that the bandwidth of the antenna is increased; at the same time, the distance between the dipole antenna groups is adjusted by the microstrip feed line, so that the signal ^ is fed into each dipole antenna group The same phase output can be achieved on the radiating element, thereby enabling the antenna to have a high gain effect, thereby achieving the purpose of a wideband and high gain folded dipole array antenna. Φ [Prior Art] According to the general dipole antenna, the light-emitting component is short, so the bandwidth and gain of the antenna are not ideal. Therefore, in order to enhance the bandwidth and gain, several dipole antennas are connected in series or in parallel. As a dipole antenna array, which is a conventional 2X2, 4X4 or more dipole array antenna, the substrate area of the antenna will increase accordingly, thereby increasing the manufacturing cost of the antenna; The Republic of China Patent Announcement No. [41816 "Dipole Antenna Array", which is composed of several dipole days, i he is in the domain - the _ dipole sky oblique column, the Cong polar sky scale p Lu line new i Lu Lin paste and bandwidth, impedance and gain, but also scales also reveal that each dipole antenna is set around a small spiral antenna to achieve a higher bandwidth; The pole antenna array can adjust its bandwidth, impedance matching and gain by the balanced line and the open cut line. 'By adding a small face-rotating antenna at both ends of the antenna to achieve a better bandwidth' The small Wei-rotating antenna starts to be wound at both ends of the dipole antenna. Therefore, the space around the small helical antenna must be limited. If a higher frequency wide antenna is required, the substrate must be enlarged, and the antenna can be broken, and the bandwidth, impedance matching and gain can be broken by balancing the line and starting the line. Therefore, in the design of the pre-gastric balance silk (4), the antenna cannot effectively paste the 5 M308514 space of the substrate; therefore, how to remove the above-mentioned defects and provide a fold with a wide frequency and a high gain in a limited substrate. The type of arbitrarily arranged antenna is the technical point that the creator wants to solve. [New content] The main purpose of this creation is to provide a folded dipole array antenna with wide frequency and high gain, comprising: = substrate, the first side of the substrate is provided with more than one set of dipole antenna groups, and one extension Ground and
