Abstract

PURPOSE:To realize two input/output terminals which resonate in frequencies being mutually different, by providing feeding points on both the long axis and the short axis of an elliptical radiation conductor element, in the microstrip antenna which is used for the mobile communication system, etc. CONSTITUTION:In the structure which consists of a radiation conductor element 1, a ground conductor 2 and a dielectric 3, and is coupled with coaxial lines 8, 12 on the reverse side of the conductors 2, an elliptical radiation conductor plate is used for the element 1. Feeding points 6, 10 are provided on both the long axis 4 and the short axis 5 of this element, and two energizing modes falling at right angles with each other are energized independently. As a result, it is possible to obtain two input/output terminals 9, 13 which are operated in different frequencies. Also, the energizing except a necessary mode is suppressed by short-circuiting the element 1 and the conductor 2 in the intersection point of the long axis 4 and the short axis 5 of the element 1. In this way, it is possible to obtain two input/output terminals which are small-sized, light in weight and low in attitude, and resonate in frequencies being mutually different.
