Abstract
Abstract A method of mounting a surface mounting antenna (10) on a mounting substrate (11), which can improve the gain. An electromotive type surface mounting antenna is mounted in the vicinity of one corner defined by the intersection of two sides (11a, 11b) of a mounting substrate (11). The surface mounting antenna (10) is mounted on the mounting substrate so (11) that an open end (2a) of a radiation electrode (2) of the surface mounting antenna (10) faces in a direction away from at least one side (11a) of the two sides (11a, 11b). <IMAGE>

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A method of mounting a surface mounting antenna on a mounting substrate (11) comprising the steps of: mounting an electromotive type surface mounting antenna (10; 20) in a vicinity of one corner defined by an intersection of two sides (11a, 11b) of said mounting substrate (11) and disposing said surface mounting antenna (10; 20) on said mounting substrate (10) with an open end (2a; 22a) of a radiation electrode (2; 22) of said surface mounting antenna (10; 20) facing in a direction away from at least one side (11a) of said two sides (11a, 11b) of the substrate (11).
Claim 2
Independent Claim
95 words
A method of mounting a surface mounting antenna on a mounting substrate (11) comprising the steps of: mounting an electromotive type surface mounting antenna (10; 20) in a vicinity of one corner defined by an intersection of two sides (11a, 11b) of said mounting substrate (11) and disposing said surface mounting antenna (10; 20) on said mounting substrate (10) with an open end (2a; 22a) of a radiation electrode (2; 22) of said surface mounting antenna (10; 20) facing in a direction away from both of said two sides (11a, 11b) of the substrate (11).
Claim 3
Dependent Claim
126 words
The method of claim 1 or 2, further comprising forming said radiation electrode (2; 22) of said surface mounting antenna (10; 20) to have one of a substantially L-shaped configuration and a substantially U-shaped configuration with a first end portion being open (2a; 22a) and a second end portion being short-circuited (2b), and arranging said radiation electrode (2; 22) and a supply electrode (3) for exciting said radiation electrode (2; 22) with a gap (g) therebetween on a main surface of the substrate comprising at least one of a dielectric substance and a magnetic substance, and connecting said radiation electrode (2; 22) and said supply electrode (3) respectively to a ground terminal and a supply terminal formed on at least one end surface of said substrate.
Claim 4
Dependent Claim
