Abstract

The invention relates to the technical field of antennas, in particular to a low profile ultra wide band antenna array setting method which overcomes the shortcoming in ultra wide band array design. A low profile ultra wide band design method is provided. An image making mode is adopted to solve the resonance problem caused by the fact that slot antenna units are adopted to form the array, then design is conducted on the array units based on the high cross coupling effect, and finally a parasitic element is adopted to adjust the working band width of the array. The method achieves antenna low profile ultra wide band characteristics and has good manufacturability and assembly capability. A metal wall image making mode is arranged between a BAVA antenna medium and a BAVA antenna floor, meanwhile the directional diagram product theorem and the electromagnetic period boundary theory are utilized to remove mutual coupling of the array units and achieve the aim of increasing band width.

Description

technical field

[0001] The invention relates to the technical field of antennas, in particular to a method for arranging a low-profile ultra-wideband antenna array. Background technique

[0002] Antennas are divided into resonant antennas (standing wave antenna, fixed frequency band) and non-resonant antennas (traveling wave antenna, wide frequency band). Traveling wave antennas are divided into four categories according to the formation principle: long antenna and loading, resonant traveling wave array, slow wave, and leaky wave.

[0003] ETSA tapered slot antennas are Vivaldi antennas, LTSA antennas, CWSA antennas or BWSA antennas.

[0004] The VIvaldi antenna is a kind of TSA antenna, which is an antenna with an exponential gradient line, and the other is an LTSA antenna. These two antennas together form a TSA antenna. The TSA antenna usually uses a microstrip line for feeding, and the microstrip line is an asymmetric transmission line, and the transmitting end of the T...
