Embodiment Construction

[0038] Figure 1A is an example of the first wireless device antenna structure 100 . The antenna 100 consists of a transmission line with two conductive surfaces 102 , 104 , lines 106 , 108 , 110 and a gap 112 . Either end of the gap 112 becomes the feed point of the antenna 100 and is connected to another RF circuit (not shown). The non-conductive material 114 covers the antenna 100 . In one example, the first antenna structure 100 is integrated into a hearing aid.

[0039] The conductive surfaces 102, 104 of the transmission line face each other and the distance between them may vary along its length. The length of the conductive surfaces 102 , 104 of the transmission line together with the position and length of the line 106 determine the resonant frequency of the antenna 100 .

[0040] Lines 106 , 108 , 110 are the main radiating elements in this antenna 100 . This is because the currents in the conductive surfaces 102, 104 oppose each other, canceling their radiatio...

Abstract

An antenna comprising: a first conductive structure having a first end coupled to a conductive strip and a second end; wherein the conductive strip is coupled to a first feed point; a second conductive structure having a first portion and a second portion; wherein the second portion is coupled to a second feed point; wherein the second end of the first conductive structure is separated from the first portion of the second conductive structure by a gap; wherein the first conductive structure substantially in parallel with the first portion of the second conductive structure and having a different width than the first portion of the second conductive structure; wherein the first conductive structure is configured to carry and the first portion of the second conductive structure is configured to carry a current of a second polarity opposite to the first polarity; and wherein the feed point is configured to carry an RF signal .

Description

technical field [0001] The present specification relates to systems, methods, apparatus, apparatus, articles of manufacture and instructions for wireless antennas. Background technique [0002] The form factors of various wireless devices, mobile or fixed, are getting smaller and smaller. For example, earbuds, hearing aids, and smartphones have shrunk in size and increased functional capabilities, such as communication between two sets of earbud pairs on different users. Upcoming Vehicle-to-Everything (V2X) and Internet of Things (IoT) devices are also planned for significant enhancements. [0003] Wireless device communications may be by means of analog or digital modulation techniques and may include data or audio information. In the case of earbuds and hearing aids, a combination of data and audio information can be transferred between the devices. The audio may be high quality audio, such as CD quality or may be of lower quality speech. In the former case, a higher b...
