Embodiment Construction

[0043] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail. It should be noted that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit or limit the present invention.

[0044] The present invention aims to design a dual-band, high-gain, omnidirectional, high-efficiency, miniaturized, and low-cost AP site / terminal antenna for mobile communication GSM900 and DCS1800 / PCS1900, and to provide dual-band or multi-band antennas for other frequency bands. The optimal design of the omnidirectional antenna provides an effective or beneficial reference method.

[0045] see Figure 1-9 , the design method of the dual-frequency high-gain omnidirectional antenna comprises the following steps:

[0046] Step 1, establish a space Cartesian coordinate system, see figure 1 ;

[0047] S...

Abstract

The invention provides a dual-frequency and high-gain omnidirectional antenna. The dual-frequency and high-gain omnidirectional antenna comprises at least two dual-frequency half-wave oscillator unitswhich are arranged on a substrate, wherein a high-frequency oscillator unit is arranged between two adjacent dual-frequency oscillator units, and the dual-frequency oscillator unit and the high-frequency oscillator unit are used for feeding by printed parallel dual-conductor feeders. The invention provides an AP station / terminal antenna, which has the characteristics of dual frequency bands, highgain, omnidirectional performance, high efficiency, miniaturization and low cost, for mobile communication, and an effective or beneficial reference method is provided for optimization and design ofthe dual-frequency or multi-frequency omnidirectional antenna in other frequency bands.

Description

【Technical field】 [0001] The invention relates to a mobile communication base station / terminal antenna device and technology, in particular to a dual-frequency high-gain omnidirectional antenna and its technology. 【Background technique】 [0002] The dream of "freely interconnecting everything" and "information wherever you want" will be realized in the 5G era. A brand-new application field of 5G communication is the Internet of Things. The Internet of Things (IoT, Internet of Things), as the name implies, is to embed wireless modules in items and network them through wireless access points (AP, Access Point), making them a network terminal that can be accessed and supervised. Due to the large number of items and the variety of categories, the number of terminal devices connected to the Internet of Things is massive, while the number of wireless access points is relatively small. Since the relative position and orientation of the terminal device and the AP are arbitrary, us...
