× Winding Process It is a process that combines an antenna and an IC loop to form a module. It takes some time to mount modules one by one on a thin board. Therefore, high costs are not suitable for mass production. However, compared with other manufacturing processes, the tag communication distance is improved. × Etching ProcessIt is a process of forming an antenna by etching aluminum or copper film on

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas. As a result, terminal antenna engineers are facing huge challenges: Antenna siz

The antenna theory of the experts is simple: http://www.52rd.com/bbs/Detail_RD.BBS_187060_42_1_3.html The problem must be analyzed in essence. The above two images can be used for analysis. Antenna evolution can be analyzed by transmission lines. The transmission lines are represented by the same axis. The same axis is divided into core, insulation layer, and shielding network. When the complete Coa

"POJ 3020" antenna Placement The maximal independent set problem of binary graphs' O ' means that the break point requires that all * connections be connected to one or two consecutive lines per route *The maximum match can satisfy only the longest path that can be formed by only two consecutive connections, and the points that are not connected need to be circled separately.i.e. N (total * number)-m (maximum match) +m (maximum match)/2(due to the fac

Reference: 1. wikipedia The dipole antenna is the simplest and most widely used class of antenna. It consists of identical conductive elements such as metal wires or rods, which is usually bilaterally symmetrical. Each side of the feedline to the transmitter or receiver was connected to one of the conductors. Dipoles is resonant antennas, meaning that the elements serve as resonators, with standing waves

Smart antenna is a kind of bidirectional antenna installed in the base station, which obtains directivity through a set of fixed antenna units with programmable electronic phase relation, and simultaneously obtains the directional characteristic of each link between the base station and the mobile station. The principle of the smart

In the previous article, we introduced what is a wireless antenna and the two basic parameters of the antenna. Next we will introduce in detail what are the outdoor wireless antennas. We have already introduced indoor wireless antennas. We will not repeat them here. Outdoor wireless antenna 1. Omnidirectional Antenna A

You can see clearly that '*' is a city, 'O' is an open space, and the antenna of an elliptical circle must cover the city '*', instead of covering the Open Space Question: In a rectangle, there are n Cities '*'. Now all N cities need to cover wireless networks. If a base station is placed, it can cover at
