CST dipole antenna simulation, half-wave dipole antenna One. In this paper, a 2013-version of a dipole antenna with a CST simulation frequency of 1GHz is used. The simulation steps are 1. Select an antenna engineering template for CST 2. Set the default units 3. Materials for setting the background (air chamber, etc.)

LTE user documentation(if there are inappropriate places, please correct me!) )9 PHY Error ModelThe physical error model consists of a data error model and a downlink control error model, both of which are activated by default. You can use the Ns-3 property system to activate, specifically:Config::setdefault ("ns3::ltespectrumphy::ctrlerrormodelenabled", Booleanvalue ( False)); Config::setdefault ("ns3::ltespectrumphy::D ataerrormodelenabled", Booleanvalue ( false));Ten MIMO Modelin this sectio

13.56 MHzSmall-sized Magnetic AntennaThe launch is catching up with the NFC heat wave. I don't understand why there are two standards in China: 2.4g and 13.56mhz. the backend protocols are easy to unify. Isn't it because of the differences in antennas? 13.56mhz is indeed a headache, and the traditional design volume is unacceptable: ApproachingBusiness card sizeAnd also consider pastingMAGNETIC FILM.

Wireless client and wireless AP in a different building, far away, in order to receive the signal, the use of the plate gain antenna, but still no signal. In general, adding an external gain antenna will increase the distance of the network connection, the network terminal has no signal, the directional fault may be directional antenna. You can adjust the

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

× 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

Source: Length calculation method of single whip antennaWhen doing radio frequency transmission, the choice and length of the antenna has a great influence on the reception sensitivity of the signal, the following is a brief overview of the antenna calculation:Alternating currents in a piece of metal wire can be emitted to the space to alternately change the induced electric field and the induced magnetic f

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

This question is to find at least how many launch devices need to be built, and the obvious binary match. However, the undirected graph is created, so it will be doubled in coverage, in fact, some points are repeated, so we need to output the total number-half of the matching points of the record ,, Antenna placement Time limit:1000 ms Memory limit:65536 K Total submissions:5576 Accepted:2793 DescriptionThe global
