[0024] best practice

[0025] FIG. 1 is an enlarged perspective view of an antenna structure 10 according to the present invention. as from Figure 1A It can be seen from the figure that the antenna of the present invention has the physical characteristics of both the patch antenna and the bow-tie slot antenna. The antenna 10 comprises a dielectric substrate element 8, such as a printed circuit board on which conductive elements are disposed. An antenna 10 is arranged opposite a ground plane 6 to which the wireless communication device is connected. The ground plane 6 may be a separate conductive element, or may comprise all or part of the ground plane of the printed wiring board of the wireless device. Antenna 10 constructed according to the dimensions shown in Figure 1 provides a dual-band frequency response covering two cellular telephone bands, namely the GSM (880-960) MHz and 3G UMTS band (1.92-2.17) GHz. see Figure 4 . The antenna shown in Figure 1 can be used for...

Abstract

The invention discloses a combination of a chip antenna dipole and a bowtie-shaped slot antenna dipole arranged on a first main surface of a dielectric element. The bow-tie slot antenna element is defined on the dielectric element within the boundary of the patch antenna element. The bow-tie slot antenna element determines the electrical resonance frequency characteristic of the first antenna, and the patch antenna element determines the electrical resonance frequency characteristic of the second antenna. The combination of the chip antenna element and the bowtie-shaped slot antenna element is arranged relative to the ground plane component, such as provided by a printed circuit board of the wireless communication device. An additional optional feature of the antenna includes a plurality of conductive radiation pattern enhancing elements disposed on opposite sides of the dielectric element.

Description

technical field [0001] The present invention relates to an antenna part suitable for the wireless transmission of analog and / or digital data, more precisely to a microstrip patch capable of operating in dual frequency bands and characterized by a high gain in each frequency band ) and bowtie slot antenna radiating element (radiating element) combination. Background technique [0002] There is a need for an improved antenna assembly which provides single and / or dual band response and which is easily incorporated into a small wireless communication device (WCD). Size constraints continue to affect radio components used in products such as cell phones, personal digital assistants, pagers, and more. The problem is further complicated for wireless communication devices that require dual-band response. The positioning of the antenna components in the WCD is critical to the overall appearance and performance of the device. [0003] Antenna components suitable for printed circuit...
