Abstract :
This paper describes a method for evaluating the performance of a magnetic core loop antenna (MCLA) used for receiving time standards via long wave radio signals. The antenna is intended for the use in radio controlled watches, wherein miniaturization and loss of sensitivity are trade-offs. Using a magnetic field simulator, we analyzed and searched for an optimum MCLA design. In addition, the performance of a radio controlled watch with the influence of a metal case is presented.
