Description

Technical Field

[0001] The utility model relates to a dual-polarization waterproof antenna, which relates to the field of television signal reception. Background Art

[0002] At present, flat-panel TV antennas on the market can usually only use one of the horizontal polarization or vertical polarization methods to receive TV signals. The bandwidth signals sent in different regions may be different. Therefore, it is uncertain which polarization method should be used for reception. For some customers who often move or change residences or workplaces, they need to purchase two TV antennas to adapt to the local bandwidth signals, thereby increasing the user's cost. At the same time, ordinary antennas generally use monopole receiving arrays, which are not conducive to the radiation angle of signal reception and affect the antenna's reception effect. Summary of the invention

[0003] The purpose of the utility model is to provide a dual-polarization waterproof antenna which can be used for receiving horizontal polarization signals and can be changed to vertical polarization receiving signals. Users only need one pair of antennas to achieve dual purposes, thereby reducing the cost of use. The antenna can receive signals in phase with the transmitting source, which is beneficial to the radiation angle of signal reception.

[0004] The technical solution adopted by the utility model is: a dual-polarization waterproof antenna, characterized in that it comprises an upper cover, a lower cover, a circuit board, a signal output terminal, a double dipole array and a base, the upper cover and the lower cover are mutually matched with concave-convex groove structures, the circuit board is installed on the lower cover, the signal output terminal is connected to the circuit board and passes through the lower cover, a slot with the same shape as the double dipole array is provided on the lower cover, and the double dipole array is embedded therein; four mounting holes are provided in the middle part of the lower cover which are symmetrical in up and down and left and right directions.

[0005] The dual-polarization waterproof antenna is characterized in that the dual dipole array is two symmetrical racket-shaped annular metal sheets.

[0006] By adopting the utility model, the antenna can be installed horizontally or vertically through four symmetrical installation holes on the lower cover, thereby realizing the conversion of the horizontal and vertical polarization receiving modes of the antenna. Therefore, the user only needs one pair of antennas to realize two modes of receiving television signals, thereby reducing the use cost for the user. At the same time, the double dipole array is more conducive to the radiation angle of signal reception than the monopole array, which is conducive to the reception of television signals.
