JP3048535U - 2-element rod antenna for mobile phones and PHS (registered trademark) phones - Google Patents

Abstract

(57) [Summary] [Purpose] By adding a horizontal antenna to the vertical antenna of a mobile phone or PHS phone, when there is a transmission / reception failure where there is an obstacle, it is possible to capture not only the vertical polarization but also the horizontal polarization. Provide transmission and reception gains. [Structure] In addition to the vertical telescopic antenna (2), the horizontal telescopic antenna (3) is mounted on the support column of the cover (5) with the axial screw, and the mounting screw (6) connected to the cover (5) is used.
Attached to mobile phones and PHS phones, the transmission and reception efficiency is increased.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an antenna mounted on a mobile phone or a PHS phone to increase the efficiency of reception and transmission.

[0002]

[Prior art]

 Heretofore, the only mobile phone antenna was a telescopic antenna (2) perpendicular to the mobile phone (1).

[0003]

[Problems to be solved by the invention]

 With a conventional vertical antenna, if the vertical polarization (7) transmitted from the base station is transmitted and received by the mobile phone antenna (2) in a vertical state, communication with the base station does not occur, but obstacles such as buildings Where there was an object, the reception sensitivity was low, and the transmission radio wave was also inefficient and had many obstacles to communication. Also, depending on how the mobile phone was held, the antenna (2) was horizontal, and the transmission / reception gain was low, making communication difficult. In such transmission / reception, transmission / reception impairment causes horizontal polarization to hit buildings or the like and various reflections, and the original vertical polarization (7) becomes flat polarization etc. (8), and the transmission / reception efficiency with the vertical antenna (2) decreases. Is the thing. Also, if the mobile phone (1) is held obliquely in the presence of weak radio waves in the presence of obstacles, the vertical antenna (2) also becomes oblique, making it difficult to receive vertical radio waves and reducing the transmission / reception effect in many cases.

[0004]

[Means to solve the problem]

 In order to solve the above problem, a horizontal antenna was attached to the vertical antenna (2) compactly on the same fulcrum. Note that two horizontal antennas can be provided. In addition, since the vertical and horizontal antennas are mounted with axial screws, L-shaped and V-shaped mobile phones can be provided.

[0006]

[Function] The vertical antenna (2) and the horizontal antenna are attached to the fulcrum provided on the cover with the shaft screws, and the new model is assembled into the mobile phone antenna mounting section incorporated in the new model. By installing it on a mobile phone with the mounting screw (6) provided in the above, vertical and horizontal polarized waves can be transmitted and received.

[0007]

[Effect of the invention]

 According to the above idea, not only the vertical radio wave but also the horizontal polarized wave can be transmitted and received efficiently by the present invention under the weak radio wave condition with obstacles. In addition, the present invention provides efficient reception even when the mobile phone is inclined.
