Embodiment Construction

[0017] Accordingly, the present invention advantageously provides antenna arrangements and associated methods for mobile stations or other radios operable in multiple frequency bands.

[0018] In overall operation an embodiment of the present invention provides a means by which to form a hybrid strip antenna for a multimode mobile station or other radio that can operate in, for example, the 800 / 900 / 1800 / 1900 MHz frequency bands.

[0019] In one aspect of the invention, the antenna is formed by first and second radiating elements comprising an annular stripline and an L-shaped stripline. The radiating element is configured to resonate at a frequency corresponding to a frequency band in which the radio can operate.

[0020] In one aspect of the invention, a substrate is provided having dimensions such that it can be disposed within the housing of a mobile station or other radio device of small size. The substrate is rectangular, or other geometric shapes and structures, and may...

Abstract

Antenna apparatus, and an associated methodology, for a multi-frequency-band-capable radio device, such as a quad-band mobile station. The antenna apparatus forms a hybrid strip antenna having a pair of resonant elements. A first resonant element forms a peripheral loop extending about the periphery of a substrate. A meander line extends along a portion of the peripheral loop. And, second resonant element is formed of an L-shaped strip. The peripheral loop is resonant at a set of frequencies, and the L-shaped strip is resonant at a single frequency. Through appropriate selection of the lengths of the resonant elements, the frequencies at which the elements are resonant are controlled.

Description

technical field [0001] Broadly, the present invention relates to an antenna structure for a mobile station or other radio device operable in multiple frequency bands. More particularly, the present invention relates to antenna arrangements and related methods for forming hybrid strip antennas for multi-mode mobile stations or other radios operable in eg 800 / 900 / 1800 / 1900 MHz frequency bands. [0002] The antenna comprises a radiating element comprising an annular stripline comprising, as a part, a meander and an L-shaped stripline, both arranged on a substrate and constructed to correspond to the frequency band in which the radio operates. resonate at the corresponding frequency. The antenna features a small size and exhibits stable frequency band characteristics and radiation patterns. Background technique [0003] The availability and use of mobile radio communication systems for communication has become an essential part of everyday life for many people. Cellular and c...
