Symmetrical slotted monopolar antenna

Abstract

A symmetrical slot monopole, including: the metal board that forms an earthing part and uses to provide the earthing loop of the monopole; the radiant part whole formats the earthing part that uses to receive and radiates the feedback signal of the signal cable.

Description

technical field [0001] The present invention relates to a monopole antenna structure, in particular to a symmetrical slot monopole antenna. Background technique [0002] With the advent and development of the wireless communication era, the design of many communication products tends to be miniaturized. In order to comply with this design trend, the volume and size of the antenna must also be reduced. The commonly used micro-miniature antennas are planar antennas ( Planar antenna) and chip antenna (chip antenna), where there are many types of planar antenna design, for example, micro-strip antenna (micro-strip antenna), printed antenna (printed antenna) or inverted F antenna (planar inverted-F antenna, PIFA), etc. Generally speaking, printed circuit board-type dipole antennas are often used in wireless communication products, and the structure of dipole antennas is taken as an example. The radiating part extends to both ends of the antenna, so it has a relatively The long s...

[0002] With the advent and development of the wireless communication era, the design of many communication products tends to be miniaturized. In order to comply with this design trend, the volume and size of the antenna must also be reduced. The commonly used micro-miniature antennas are planar antennas ( Planar antenna) and chip antenna (chip antenna), where there are many types of planar antenna design, for example, micro-strip antenna (micro-strip antenna), printed antenna (printed antenna) or inverted F antenna (planar inverted-F antenna, PIFA), etc. Generally speaking, printed circuit board-type dipole antennas are often used in wireless communication products, and the structure of dipole antennas is taken as an example. The radiating part extends to both ends of the antenna, so it has a relatively The long antenna structure length leads to the size of the wireless communication product being limited by the size of the antenna and it is difficult to miniaturize, and the production process of the printed circuit board antenna is relatively complicated and the production cost is also high

[0003] In addition, in order to increase the speed of wireless transmission, a multiple input / output (MIMO) antenna has gradually been favored by users in recent years. It mainly uses multiple independently set antennas, which are respectively connected to the signal processing switching circuit. , taking three antennas as an example, two of the antennas are responsible for receiving / transmitting, and one antenna is responsible for receiving. The antenna structure will make the volume of the antenna more bulky, which does not meet the current product design requirements
