Portable type wireless device

Abstract

A portable wireless device operating in a frequency range. The casing of the portable wireless device is equipped with conductive components such as a circuit board, a battery, a card slot, a multimedia connector, and a resonator. The resonator uses dielectric material as the main body, and forms positive electrodes and negative electrodes on opposite sides of the dielectric material. The positive electrode has a positive trimming piece and the negative electrode has a negative trimming piece. There is a capacitive effect between the positive and negative trimming pieces to adjust impedance matching and phase. When the resonator operates at a resonant frequency, energy can be coupled to the conductive elements to collectively produce the radiated field of the portable wireless device.

Description

technical field [0001] The present invention relates to a wireless device, in particular to a portable wireless device. Background technique [0002] In recent years, the electronic industry has developed vigorously. In addition to the thin, light and compact appearance of electronic products, the ability of wireless communication is also increasingly valued. For example, notebook computers, mobile phones (called mobile phones) or personal digital assistants (Personal Digital Assistant, PDA), their wireless communication capabilities are ruthlessly subjected to the strictest scrutiny in the market, and have become important reference indicators for performance. Especially for personal digital assistants, its compact size and wireless network function have always been the biggest selling points, so various manufacturers are all doing their best to carry out research and development to seize business opportunities. [0003] In wireless applications, the antenna is a very impo...

AI Technical Summary

Problems solved by technology

More specifically, many conductive elements are unavoidably configured inside the PDA, such as circuit boards, batteries, card slots (such as memory cards or I / O cards) and multimedia connectors (such as microphone or earphone connectors), etc., due to these conductive elements Both reflect or absorb wireless signals, thus directly affecting the transmission characteristics of antenna signals

In other words, the traditional antenna may work well if it can exclude the condition that there are conductive elements nearby, but when the antenna is placed in the case, the operating characteristics will be greatly reduced due to the influence of environmental factors, which directly affects the wireless signal. send and receive quality

Of course, such problems do not only occur in the design of PDAs, other portable wireless devices such as mobile phones or laptops, as long as they have hidden antennas, will face the same problem, which is quite a headache
