Abstract

The invention relates to the technical field of antennas, in particular to a combined antenna applied to a road side unit, which comprises transceiver equipment, a broadband high-gain double-frequencyantenna, a broadband omnidirectional antenna and an active antenna, wherein a first PCB and a first connecting cable are arranged in the broadband high-gain double-frequency antenna; a 2.4 GHz radiation array unit, a 5GHz radiation array unit and a combiner are arranged on the first PCB; a second PCB and a second connecting cable are arranged in the wide-frequency-band omnidirectional antenna; the second PCB is provided with a first radiation oscillator and a coupling oscillator. The plurality of antennas are integrated on the transceiver equipment, so that the combined antenna comprises a plurality of frequency bands; the bandwidth of the combined antenna is greatly increased, and the combined antenna is simple in structure, small in size and capable of providing good radiation performance indexes by means of the dielectric microstrip technology, the frequency division confluence technology, the broadband technology and the coupling resonance technology.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a combined antenna applied to a roadside unit. Background technique [0002] RSU is the English abbreviation of Road Side Unit, which means road side unit. It is an ETC system installed on the roadside. It uses DSRC (Dedicated Short Range Communication) technology to communicate with the on-board unit to realize vehicle identification and electronic point deduction. Device; in the management of highways and parking lots, installing RSU on the roadside can establish unattended fast and dedicated channels, and can also provide services such as high-precision positioning of vehicles and high-precision maps. Through the above communications, a safer, more A more convenient smart transportation world; [0003] However, the current roadside unit has problems of large size and narrow bandwidth. Contents of the invention [0004] The purpose of the present invention is to address th...
