Description of the Invention: [Technical Field of the Invention] The present invention pertains to the field of communications. Specifically, it relates to an antenna and a sputum antenna having the antenna. Λ [Prior Art] With the high development of semiconductor manufacturing, 'there is an increasing demand for the integration of today's electronic systems'. The miniaturization of devices has become a technical issue of great concern to the entire industry. However, unlike the IC chip, which follows the ‘‘Moore's Law, the development' as an important component of the electronic system, a radio frequency module faces a difficult technical challenge of miniaturization of the device. The RF module mainly includes main components such as mixing, power amplifier, filtering, RF signal transmission, matching network and antenna. Among them, the antenna as the radiating unit and receiving device of the final RF signal, its working characteristics will directly affect the performance of the entire electronic secret. However, important indicators such as antenna size, bandwidth, and gain are limited by basic physical principles (gain limit, bandwidth limit, etc. at fixed size). The basic principle of the limits of these indicators makes the antenna technology far more difficult than other devices, and the complexity of the electromagnetic field analysis of the RF devices has made it extremely challenging. ^时' With the complexity of modern electronic hubs, the demand for rural model services has become increasingly important in systems such as wireless communication, wireless access, satellite communications, and wireless data networks. The demand for multimode services further increases the complexity of miniaturized antenna multimodes. In addition to the miniaturized lining challenge, the day-multimode impedance matching also becomes the antenna__. On the other hand, the multi-input multi-output system (ΜΙΜΟ) in the field of wireless communication, no-line, data service, the rapid development of the 201248992 step requires the miniaturization of the antenna size while ensuring good isolation, radiation performance and Anti-interference ability. However, conventional terminal communication antennas are primarily designed based on the radiation principle of electric monopoles or dipoles, such as the most commonly used planar anti-F antenna (PIFA). The radiated operating frequency of a conventional antenna is directly related to the size of the antenna, and the bandwidth is positively correlated with the area of the antenna, so that the design of the antenna usually requires a physical length of half a wavelength. In some of the more complex electronic systems, the antenna requires multimode operation, which is the design of the impedance matching network that is to be inserted into the antenna before the antenna. However, the impedance matching network additionally increases the feeder design of the electronic system, increases the area of the RF system, and simultaneously introduces a lot of energy loss, which is difficult to meet the system design requirements of low power consumption. Therefore, the miniaturized, multi-mode new antenna technology has become an important technical bottleneck in contemporary electronic integrated systems. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide an antenna that is guaranteed to be miniaturized during low frequency operation in view of the drawbacks of the prior art that the antenna is controlled by the physical limitations of the spatial area when operating at low frequencies.
