Description

Combined antenna device and electronic equipment Technical Field The application belongs to the technical field of antennas, and particularly relates to a combined antenna device and electronic equipment. Background With the development of modern communication technology, the position of an antenna is more and more important, the requirements on the communication distance and the applicable environment of the antenna are also higher and higher, and the gain and the directivity influence the performance of the whole communication system. If only a directional antenna is used, if the main gain direction of the antenna of the transmitting device deviates from the main gain direction of the antenna of the receiving device by a certain angle, the coverage area of the device using the directional antenna for communication is relatively limited, so that the gain of the whole system is insufficient. For communication devices moving in wide angular ranges within close range, in some air ranges, the target device cannot receive signals propagating in the air, resulting in communication disruption. The solution includes adjusting the direction of the directional antenna by using a servo system or a mechanical rotation mode, and the method has the advantages of wide coverage range and high gain, but consumes time, improves the weight of the whole machine, and increases the time and financial cost. If only using the omni-directional antenna, the gain is low and the communication distance is short under the same electric size, if the omni-directional coverage is ensured and the gain is improved, the number of the units of the antenna can be increased, so that the size is large, and larger multipath interference is easy to be introduced, which is not beneficial to practical use. Communication devices on the market today typically use antennas that are separate from the directional and omni-directional antennas in order to solve the problem of communicating near and far ends at a small cost. However, for the low frequency band, the antenna size is relatively large, and an omni-directional antenna is additionally manufactured, so that the two antennas are separately arranged to occupy a large volume, and meanwhile, the manufacturing cost is increased.
