Microstrip antenna device for circularly polarized waves |
摘要 |
A microstrip antenna device for circularly polarized waves includes a dielectric sheet member, one surface of which has a radiating conductor sheet member while the opposite surface has a ground conductor sheet member. Denoting a point where a segment of a line passing through a geometrical center o, o of the radiating conductor sheet member intersects with the substantial periphery of the radiating conductor sheet member by a and denoting a point where the segment intersects with the substantial periphery of the ground conductor sheet member by b, the ratio of the length between the points o and b to the length between the points o and a should be at least equal to 1.5. Where rectangular radiating and ground conductor sheet members are used, a good circular polarization is achieved without any disturbance in the radiating pattern when the diagonal ratio of the respective members is equal to or greater than 1.5.
