A Broadband Electro-Magnon Combination Antenna Excited by Microstrip-Slot

Abstract

The invention discloses a mcrostrip-gap incentive broadband electric-magnetic vibrator combined antenna. A gap is etched in a shielding conductor of a dielectric substrate with a dielectric constant ranging from 2 to 20, a microstrip feeder and a tuning supporting node are manufactured on the other face of the dielectric substrate, an antenna body of a dipole-groove line combination structure is vertically connected to a position above the gap, the antenna body of the dipole-groove line combination structure is formed in the mode that a top-layer radiation unit and a bottom-layer radiation unit which are antisymmetrical are designed on the dielectric substrate with the dielectric constant ranging from 2 to 20 in a combined mode, and the top-layer radiation unit and the bottom-layer radiation unit are connected to the two sides of the gap in a crossed mode. An eccentric microstrip line feed mode is adopted, the position of a feeding point, the length of the feeder, the length of the tuning supporting node and the length of a vibrator are changed, the broadband beam antenna with good performance can be obtained, under the condition of not adding a reflection back cavity, high gains and a stable directional diagram can be obtained, the structure is simple and manufacturing cost is low.

Description

technical field [0001] The invention relates to a microstrip-slot excited broadband electro-magnetic vibrator combined antenna, which belongs to the field of microwave technology. Background technique [0002] In recent years, with the rapid development of wireless communication technology, the application of WLAN wireless local area network and radio frequency identification system is increasing, and the requirements for indoor signal coverage are getting higher and higher. However, the directional antennas in the existing indoor signal coverage systems have complex structures, limited bandwidths, and poor gain performance, and cannot cover the frequency bands of multiple standard wireless communication systems. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a microstrip-slot excited broadband electro-magnetic vibrator combined antenna for the problems existing in the background technology. In the case of a ca...
