An edge-enhanced indoor coverage vertically polarized omnidirectional ceiling antenna

Abstract

The invention provides an edge-enhancement indoor coverage vertically-polarized omnidirectional ceiling antenna, which comprises a floor and a cuppy radiator, wherein the floor and the cuppy radiator are rotary bodies employing respective central lines as axes; the central line of the cuppy radiator overlaps with the central line of the floor; the floor and the cuppy radiator are connected with an outer conductor and an inner conductor of a feed cable respectively; the cuppy radiator comprises two cylindrical parts and two conical parts, which are sequentially connected and are different in diameter; the diameter of the cuppy radiator is gradually reduced towards the direction of the floor; step parts are formed at the connected part of the two cylindrical parts and the connected part of the two conical parts due to sudden changes of the diameters; a bulge part toward the direction of the cuppy radiator is arranged at the center of the floor; and folded edges which are opposite in direction are arranged on the circumference of the floor. The design still keeps relatively high gain in a low elevation direction; and a broadband, the omnidirectivity, vertical polarization, edge effect enhancement, in-band uniform coverage, a small size and a low profile superior to those of a conventional single-cone omnidirectional ceiling antenna are achieved.

Description

technical field [0001] The invention relates to an indoor distributed omnidirectional ceiling antenna for cellular mobile communication, in particular to an edge-enhanced indoor coverage vertically polarized omnidirectional ceiling antenna. Background technique [0002] At present, mankind has entered the information age in an all-round way, and obtaining information has become an indispensable part of people's daily life. With its unique convenience, mobile communication has become the main way for people to obtain information and communicate with each other anytime and anywhere. The antenna is a key sub-component of the wireless communication system, and its performance has a decisive impact on the entire system. With the development of mobile communication technology, indoor environments such as homes, offices, shopping malls, terminal buildings, classrooms, libraries, etc. have become hot spots for traffic and data traffic. Due to consideration of coverage, site select...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problem that the omnidirectional ceiling antenna adopts a single-cone antenna with low elevation gain and poor out-of-roundness, and adopts a double-cone antenna that is too large in size, and provides an enhanced edge effect and consistent coverage within the band. , small size, low profile edge-enhanced indoor coverage vertically polarized omnidirectional ceiling antenna
