CHIP ANTENNA ELEMENT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a chip antenna element capable of improving variation in frequency characteristics and the like at resonance. SOLUTION: A chip antenna 10 is provided with a radiation electrode 13, ground electrodes 15 and 17 and the like on an insulating substrate 11. Here, a recessed part 19 such as a groove is provided between the radiation electrode 13 and the ground electrodes 15 and 17. The recessed part 19 such as a groove specifies the distance between the radiation electrode 13 and the ground electrode 15 and 17 while a large width is selected to be an appropriate value depending on the depth and/or width of the recessed part 19 such as a groove.
