Abstract: A contactless feed patch antenna including a generally planar first conductive sheet provided as a ground plane, and a second conductive sheet provided as a radiative element. The second conductive sheet includes a generally planar first radiative region arranged substantially parallel with the first conductive sheet, and a second radiative region including a non-parallel portion arranged in a non-parallel plane to that of the first radiative region.

Abstract: A radiation antenna for wireless communication provides an advantage of being able to enhance gain and control directionality, while suppressing the height. The radiation antenna for wireless communication includes a line antenna element 10 and arm elements 20. The line antenna element 10 extends from a power feed section 15. The arm elements 20 are connected to a tip portion of the far side from the power feed section 15 to enhance the gain of the line antenna element 10 and control the directionality thereof. The electrical length from the power feed section 15 to the open end of the arm elements 20 by way of the line antenna element 10 is designed to resonate at a higher order mode of a target frequency.

Abstract: A vehicular screen antenna includes a conductor extending on a dielectric, such as a window. The conductor is configured as a loop having entry and exit segments, the loop being positioned generally centrally on the dielectric. The entry and exit segments extend proximate each other from the loop towards a first edge of the dielectric and are oriented on the dielectric so as to extend generally vertically when the dielectric is fitted to a vehicle.

Abstract: A high-bandwidth multi-band antenna includes a ground plane member, a first patch member extending in generally-parallel spaced relationship with the ground plane member and electrically connected thereto, and a second patch member connectable to a signal feedline and extending generally coplanar with the first patch member within a slot formed in the first patch member. The second patch member is formed integral with a vertical conductive connecting member as part of a folded conducting plate; this construction allows the second patch member to be quickly and accurately positioned relative to the ground plane member before attachement to the ground plane member. The antenna has the advantages of a high bandwidth, simple construction and inexpensive manufacture.
