PROBLEM TO BE SOLVED: To provide a pattern antenna dealing with the arrangement of an RF module on a dielectric substrate while maintaining and improving antenna performance. SOLUTION: This pattern antenna constitutes an inverse F type antenna, and a microstrip line 13 for power feed is formed on the surface opposite to a planar radiation conductor 5 of a resin substrate 1. An RF module 15 is provided on the surface opposite to the conductor 5 of the resin substrate 1. A grounding conductor 3 is provided on both the surfaces of the resin substrate 1. Connections between a branch 5c and the microstrip line 13 and between both the conductors 3 are performed by through holes 11, 17. COPYRIGHT: (C)2005,JPO&NCIPI
