US 5510802 AAbstract
1. A surface-mountable antenna unit comprising:a dielectric substrate having a top surface, a substantially flat bottom surface for surface-mounting, and side surfaces; a ground electrode being formed on at least one of a side surface and a bottom surface of said dielectric substrate; a radiator, having a major surface and consisting of a material having low conductor loss, being fixed to said dielectric substrate so that its major surface is opposed to the top surface of said dielectric substrate, to thereby form a laminate of said dielectric substrate and said radiator; and a feed part being provided at least on one of a side surface and a bottom surface of said laminate formed by said dielectric substrate and said radiator wherein said radiator comprises a radiating part having said major surface, and at least one fixed part extending from at least one edge of said radiating part toward said dielectric substrate, said at least one fixed part being fixed to said side surface of said dielectric substrate, thereby fixing said radiator to said dielectric substrate, and further comprising a feed terminal and a ground terminal being integrally formed on said at least one fixed part of said radiator. 2. A surface-mountable antenna unit in accordance with claim 1, wherein said major surface of said radiator is in contact with said top surface of said dielectric substrate.
9. A surface-mountable antenna unit in accordance with claim 1, Wherein said radiating part has a rectangular plane shape being provided with longer and shorter sides,said feed terminal and said ground terminal being arranged on the same said side of said radiating part. 10. A surface-mountable antenna unit in accordance with claim 9, wherein said feed terminal and said ground terminal are arranged on said longer side of said radiating part.
12. A surface-mountable antenna unit in accordance with claim 1, wherein said radiating part has a rectangular plane shape being provided with longer and shorter sides,said feed terminal and said ground terminal being arranged on different said sides of said radiating part. 13. A surface-mountable antenna unit in accordance with claim 1, further comprising a capacitor being electrically connected between said ground electrode and said radiating part.
20. A surface-mountable antenna unit in accordance with claim 19, wherein said radiating part has a rectangular plane shape,said stop member being formed on a side being different from that provided with said fixed part. 21. A surface-mountable antenna unit in accordance with claim 19, wherein said radiating part has a rectangular plane shape,said stop member being formed on the same said side as that provided with said fixed part. 22. A surface-mountable antenna unit in accordance with claim 21, wherein a pair of stop members are arranged on both sides of at least one said fixed part, forward ends of said pair of stop members being in contact with said top surface of said dielectric substrate.
34. A surface-mountable antenna unit in accordance with claim 33, wherein said radiating part has a rectangular plane shape being provided with longer and shorter sides,said feed terminal and said ground terminal being arranged on the same said side of said radiating part. 35. A surface-mountable antenna unit in accordance with claim 34, wherein said radiating part has a rectangular plane shape being provided with longer and shorter sides,said feed terminal and said ground terminal being arranged on said longer side of said radiating part. 36. A surface-mountable antenna unit in accordance with claim 34, wherein said feed terminal and said ground terminal are arranged on said shorter side of said radiating part.
37. A surface-mountable antenna unit in accordance with claim 33, wherein said radiating part has a rectangular plane shape being provided with longer and shorter sides,said feed terminal and said ground terminal being arranged on different said sides of said radiating part. 38. A surface-mountable antenna unit in accordance with claim 31, further comprising a capacitor being electrically connected between said ground electrode and said radiating part.
42. A surface-mountable antenna unit comprising:a dielectric substrate having a top surfacer a bottom surface and side surfaces; a ground electrode being formed on at least one of a side surface and a bottom surface of said dielectric substrate; a radiator, having a major surface and consisting of a material having low conductor loss, being fixed to said dielectric substrate so that its major surface is opposed to the top surface of said dielectric substrate; and a feed part being provided at least on one of a side surface and a bottom surface of a laminate formed by said dielectric substrate and said radiator; further comprising a shield electrode being formed on said dielectric substrate, said shield electrode being electrically connected to said ground electrode, and said radiator has a radiating part and an annular side wall part extending from an edge of said radiating part toward said dielectric substrate, a flange part being formed on a forward end of said annular side wall part, said flange part being electrically connected to and mechanically bonded with said shield electrode, thereby defining a space of a prescribed thickness between said radiating part and said dielectric substrate. 43. A surface-mountable antenna unit in accordance with claim 42, wherein said shield electrode and said ground electrode being formed on said side surface of said dielectric substrate are electrically connected with each other by a via hole electrode being formed in said dielectric substrate.
