Development of the indoor propagation environment improvement technology

In this report, it was described that the reflector that forms focal point can be achieved though it is plane shape if the patch element with different shape and size is located one by one. As a result, it was confirmed that the input reactance with patch element loadings can be approximated to positional movement of the reflector within 0.47 to 0.53 GHz. Additionally, the correlation of the size of the loadings patch element and equivalent reflection position shift distance was clarified. As a future, we are going to carry out the amount of a advance expand when change the shape of the patch element.
