Problems solved by technology
[0005] However, since the reflective surfaces of known antenna reflectors are mostly spherical, parabolic or other special curved surfaces, in order to precisely control the position of the focal point generated by such curved surfaces and maintain the same curvature on all parts of the curved surface, the processing and manufacturing of curved surfaces is extremely difficult. Difficult, thus leading to a substantial increase in manufacturing costs, and because of the difficulty in processing, it is difficult to miniaturize the antenna reflector with such a curved surface structure
[0006] In addition, because the known antennas with reflectors can only be used in a single frequency band, they cannot simultaneously comply with the IEEE802. GHz), and the frequency band requirements of the European HYPERLAN standard (used frequency is about 5.9GHz), thus increasing the inconvenience and cost of use

Antenna assembly in multiple frequencies with reflection board meets requirement of antenna in dual frequencies or more frequencies. The antenna assembly in multiple frequencies is composed of radiator and structure of box type reflection board. Structure of the box type reflection board possesses a baseboard, and a sideboard of surrounding the baseboard. The radiator is connected to surface of the baseboard faced to the sideboard. There is an extended board encircling one side of the sideboard faced to the baseboard. Being parallel to the baseboard, the extended board is extended along outside of the box type reflection board. The extended board also can be a frame subassembly with an opening. One side of the sideboard faced to the baseboard is connected to periphery of the opening.
Description
technical field [0001] The invention relates to a multi-frequency antenna device with a reflector, in particular to a multi-frequency antenna device with a box-shaped reflector structure. Background technique [0002] With the vigorous development of communication technology, various communication products and technologies have sprung up like mushrooms after rain. Coupled with the increasingly mature technology of integrated circuits, the volume of products tends to be thinner and smaller. For the antenna used to transmit and receive signals in communication products, the size of the antenna is even more critical to whether the communication product can achieve the goal of being thin, light and small. [0003] The antenna is a component used to radiate or receive electromagnetic waves. Generally, the characteristics of the antenna can be obtained from parameters such as operating frequency, radiation pattern (Radiation Pattern), return loss (Return Loss) and antenna gain (A...
