Embodiment Construction

[0018] figure 1 is a schematic diagram of the structure of a linear microstrip antenna array, k (k≥2) array units 51 are arranged along a straight line at a certain distance, and the distance d of the array units 51 is not greater than one wavelength, and d depends on the required beam width, sector The angle of area coverage is determined, and the array unit is fixed on the support base plate 52, which is a metal plane for grounding.

[0019] In general, when the radiator of the array unit is a microstrip, its feeding network is also in the form of a microstrip, so the radiator and the feeding network are integrated, and the structural form of the array unit is a plane. According to different forms of microstrip radiators, the direction of the maximum value of the pattern is different. When the radiator is a patch antenna, the direction of the maximum value of radiation is in the normal direction of the array element surface, so when the array elements are arranged in an arra...

Abstract

The antenna array is composed two more identical array units arranged along a straight line with equal interval or unequal interval on a plane supported. Arranged interval of array units can be half wavelength of operation frequency in free space, and largest wavelength is not larger than one wavelength. The array unit includes radiator, feeding network and coaxial connector. The radiator of the array unit is radiator in vibrator or microstrip types. The invention possesses features of good S / N ratio in channel, low transmitting power of terminals. The invention is suitable for building network in sectors and has advantages of adjusting coverage area smartly, increasing capacity of system and convenience of construction.

Description

technical field [0001] The present invention relates to an antenna array in communication technology and a method for designing the vertical plane pattern of the antenna array, in particular to a linear smart antenna array for mobile communication and a vertical plane pattern shaping design based on the antenna array Methods. It belongs to the field of mobile communication. Background technique [0002] With the rapid development of mobile communication, the number of users has grown rapidly. However, due to the constraints of wireless conditions such as limited wireless spectrum resources, complex wireless transmission environment, and near-far effect, the current mobile communication technology has a lot of problems in terms of system capacity, communication quality, and types of services provided. It is difficult to meet the growing consumer demand in many aspects, so the study of smart antenna technology in the field of mobile communication has become an important topic...
