    Abstract: PROBLEM TO BE SOLVED: To provide the improved inverted-F planer antenna. SOLUTION: The antenna 30 has a ground plane 34 with an opening 42, a radiation patch 38 placed in a 1st dielectric base 36 made of a foaming material or other dielectric material, and a feed line base 32. A short-circuit strip 40 is used to connect one side of the radiation patch 38 to the ground plane 34 at a point thereof where a microwave in the major mode of the radiation patch 38 is at a null point. A feed line 44 of a microstrip is placed to the feed line base 32 being a 2nd dielectric base opposite to the other side of the ground plane 34.

    Abstract: PROBLEM TO BE SOLVED: To solve problems of a conventional patch antenna by providing a nonconductive frame supporting a resonator. SOLUTION: The nonconductive frame 124 supports the resonator 116 of a patch antenna assembly 100. Since the frame 124 supports the resonator 116 without the need for making holes to the resonator 116, a problem of generating an undesired wave with polarized electric field can be avoided. Moreover, the frame 124 grips the resonator 116 at an are with a low current density thereby preventing further disturbance from being caused to a radiation pattern. The frame 124 may be provided with posts 128 used to be mounted onto a supply board 130 without the use of additional components such as screws.

    Abstract: A non-conductive frame (124,126) supports the resonators (116,118) in a patch antenna assembly (100). The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also include posts (128) that are used to attach the frames to the feedboard (130) without using additional components such as screws.

    Abstract: An aperture-coupled planar inverted-F antenna (PIFA) including a radiating patch formed on one side of a ground plane and separated therefrom by a first di electric which may be air, foam or another suitable material. A shorting strip connects a side of the radiating patch to the ground plane at a point corresponding to a dominant m ode null, such that the size of the radiating patch may be reduced by a factor of tw o. A microstrip feedline is arranged on an opposite side of the ground plane and sepa rated therefrom by a second dielectric which may be part of a substrate formed of prin ted wiring board material. Signals are coupled between the microstrip feedline and t he radiating patch via an aperture formed in the ground plane. The use of aperture coupling avoids the excessive cost associated with conventional TEM transmission line or coaxial feeds, while providing improved manufacturability and ease of integra tion relative to PIFAs with conventional feeds. Moreover, the aperture coupling prov ides improved tuning flexibility. For example, a portion of the microstrip feedline m ay be used as a tuning stub to provide impedance matching on the feedline.
