Abstract

The embodiment of the invention discloses a double-ridge horn antenna and electronic equipment. The double-ridge horn antenna comprises a first radiation oscillator, a second radiation oscillator and an impedance conversion balun. The first radiation oscillator comprises a first part and a first radiation part. The second radiation oscillator comprises a connecting part and a second radiation part. The impedance conversion balun comprises a first part, a second part and a third part which are connected in sequence and form a U shape. The end, away from the third part, of the first part is connected with the first radiation part, and the end, away from the second part, of the third part is connected with the connecting part. The first radiation part and the second radiation part extend in the same direction. A gap is formed between the first radiation oscillator and the second radiation oscillator, and a signal is fed in from the gap. According to the double-ridge horn antenna and the electronic equipment, effective working bandwidth of the antenna can be ensured, and the current generated by high-order mode excitation caused by impedance mismatching can be eliminated.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a double-ridge horn antenna and electronic equipment. Background technique [0002] Currently, most wireless electronic products use built-in antennas with a dipole topology. On the one hand, the bandwidth of the dipole antenna can only reach 15% usually, and there is a problem that the bandwidth is not enough to be effectively applied to the ultra-wideband communication system; on the other hand, although the impedance transformation balun structure of the dipole antenna can effectively suppress the high The current interference of the secondary mode signal greatly improves the radiation efficiency of the antenna. However, since the dipole antenna has an impedance transformation balun structure, the characteristic impedance of the signal channel is 50Ω, while the characteristic impedance of the dipole antenna is 73Ω, where the impedance The current generated by the high-order mode excit...
