摘要： A multiband internal antenna apparatus and methods of tuning and utilizing the same. In one embodiment, the antenna configuration is used within a handheld mobile device (e.g., cellular telephone or smartphone). The device enclosure is fabricated from a conductive material and has two parts: the main portion, housing the device electronics and ground plane, and the antenna cap, which substantially envelops a directly fed radiator structure of the antenna. Electromagnetic coupling of the cap portion to the device feed effects formation of a parasitic antenna radiator in a lower frequency band. The cap portion is separated from the main portion by a narrow gap, extending along circumference of the device, and is grounded at a location selected to cause desired resonance and to widen antenna bandwidth. In one implementation, a second parasitic radiator is disposed proximate the directly feed radiator to further expand antenna frequency bands of operation.

摘要： A multiband antenna applicable as an internal antenna in small mobile terminals especially. The antenna (200) is a PIFA placed inside the housing of a mobile station with at least two operating bands. A first resonance falling into a lower operating band is produced by means of a radiating conductive pattern (B21) in planar element (220). To improve the characteristics of the antenna in the upper operating band the planar element further comprises a slot (232) which goes between the feed point (F) and the short-circuit point (S) of the antenna. The radiator provided by this slot can be considered a quarter-wave slot radiator or a half-wave loop radiator. The PIFA further may have another radiator, which resonates in the upper operation band. By means of said slot the upper operating band of an antenna can be widened or the radiation in the horizontal plane in the upper operating band can be made more effective.
摘要翻译：特别是在小型移动终端中用作内部天线的多频带天线。天线（200）是放置在具有至少两个操作频带的移动台的壳体内的PIFA。通过平面元件（220）中的辐射导电图案（B21）产生落入较低工作频带的第一共振。为了改善上部工作带中的天线的特性，平面元件还包括一个位于馈电点（F）和天线的短路点（S）之间的槽（232）。由该槽提供的散热器可以被认为是四分之一波长的槽式散热器或半波浪式散热器。 PIFA还可以具有另一个散热器，其在上部操作频带中共振。通过所述槽，天线的上部工作频带可以被加宽，或者可以使上部操作频带中的水平面中的辐射更有效。

摘要： The invention relates to dual mode antennas particularly suitable for mobile stations. The antenna structure comprises an antenna (211, 201, 202, 212) of the PIFA type which is located within the covers of the mobile station, and a whip element (220) which is movable relating to the PIFA antenna. The PIFA can be a single band or a dual band antenna. When the whip element is extracted its lower end (222) forms a galvanic or capacitive coupling with the radiating element (211) of the PIFA. If the PIFA is a single band antenna the extracted whip element substantially changes the resonant frequency of the PIFA, so that the whip is left as the radiating element at the operating band. If the PIFA is a dual band antenna, then an extracted whip alone, or the whip and the planar element of the PIFA together, functions as the radiating element at one operating band, and at the other operating band the planar element of the PIFA operates as the radiating element. The feeding and the matching of the whip element is arranged by the PIFA without any separate additional components. With the aid of the invention the best properties of both the PIFA and the monopole antenna can be utilised. The structure is further reliable and it has relatively low costs.

摘要： The invention relates to an antenna structure (400) to be placed inside in particular small radio apparatus. A conventional PIFA-type structure is extended by arranging a structural part (415) adding to the capacitance between the radiating plane (420) and ground plane (410) relatively close to the feed point (F) of the antenna. The structural component may be a projection extending from the radiating plane towards the ground plane or vice versa. An advantage of the invention is that it achieves a significant increase in the antenna bandwidth without increasing the size of the antenna. Another advantage of the invention is that the structure according to it is simple and the increase in the manufacturing costs is relatively low.

摘要： A planar antenna comprises a planar radiating element (600) formed of a conductive area confined by a substantially continuous border line. The conductive area is split by a gap which divides the planar radiating element into a first branch and second branch such that both the first and the second branch have an outermost end. The gap has a head end on said substantially continuous border line and a tail end within the conductive area. At its head end (601) the gap has a certain first direction and at another point (603) a certain second direction which differs from the first direction by more than 90 degrees when the directions are defined along the gap from the head end towards the tail end. The outermost end of the second branch, confined by the gap, is located within the continuous border line, surrounded by the first branch.

It comprises a planar radiating element (801, 1002, 1101, 1203) which is a conductive area confined by a substantially continuous border line divided by a non-conductive slot (802).
