hyperlink antenna

Antennas are rectangular, circular, and rod-shaped. Generally, the longer the communication distance is, the larger the size of the antenna. However, in actual use, when tags are attached to an item, even the RFID tags of the business card size are too large. In fact, the size and shape of the RFID tag in use need to be selected based on the communication distance. Currently, antenna materials include al

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

Each time we can use a rectangle of 1X2 to cover the map, we can use at least a few to cover the map.

The main problem: There are N cities, to establish a radio station in these n cities, each radio station can only cover 2 neighboring cities, ask at least how many wireless power stations need to buildProblem-Solving ideas: English topic good pit, looked at half a day.This problem is similar to POJ-2446 chessboard.All cities can be divided into two point sets, then the connection between the radio station to represent the coverage of the relationship.Because all cities have to be covered, so acc

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 most two adjacent cities.How many base stations can be placed to ensure that all cities are wireless? Ideas: Number each city, create two-way edge, run Hungary, and then the number of cities-matching number/2 is the answer Assume that each city needs to build a base station, and then how many matches will reduce the number of base stations. Because the
