Abstract
A microstrip antenna (4) has a radiation electrode (2) and a ground electrode (3) which are formed on upper and lower surfaces of a dielectric substrate (1) respectively. A feeding terminal electrode (2c) of the radiation electrode (2) is formed on the lower surface of the dielectric substrate (1), which is provided with the ground electrode (3), and is insulated from the ground electrode (3). A feeding point (2a) of the radiation electrode (2) is connected with the feeding terminal electrode (2c) by a through-hole electrode (2b). The feeding terminal electrode (2c) is formed in the same plane as the ground electrode (3). In another embodiment of the invention, a through-hole electrode (12b) extends from a feeding point (12a) to the plane of the ground electrode (13).
