UHF/VHF planar antenna device, notably for portable electronic equipment
Abstract:
A planar antenna device (AD) for a TV receiver (R) comprises i) a loop antenna (LA) comprising first (E1) and second (E2) ends spaced one from the other, ii) a tuning means (TM) connected to the first (E1) and second (E2) ends of the loop antenna (LA) and arranged to control the frequency of the VHF TV signals this loop antenna (LA) is able to receive from command signals, iii) a first ground plane (GP1) cooperating with the loop antenna (LA) in order to act as a UHF monopole in receiving TV signals with UHF frequencies, iv) a first coupling means (CM1) coupled to the loop antenna (LA) at a first chosen location and arranged to deliver the received VHF signals, v) a second coupling means (CM2) coupled to the loop antenna (LA) at a second chosen location and arranged to deliver the received UHF signals, vi) an amplification means (AM) coupled to the first ground plane (GP1) and arranged to amplify TV signals, and vii) a switching means (SM) arranged to couple the amplification means (AM) to the first coupling means (CM1) and/or to the second coupling means (CM2) in dependence on command signals in order that the amplification means deliver amplified selected TV signals with VHF and/or UHF frequencies to an output.
Abstract(Chinese):

一种用于TV接收器（R）的平面天线装置（AD）包括：i）包括彼此间隔开的第一（E1）和第二（E2）端的环形天线（LA），ii）调谐装置（TM），其连接到 环路天线（LA）的第一（E1）和第二（E2）端，并且被布置成控制该环形天线（LA）能够从命令信号接收的VHF电视信号的频率，iii）第一接地平面 GP1）与环形天线（LA）协作，以便在接收具有UHF频率的TV信号时用作UHF单极; iv）在第一选定位置处耦合到环形天线（LA）的第一耦合装置（CM1），并布置 传送所接收的VHF信号，v）在第二选定位置处耦合到环形天线（LA）的第二耦合装置（CM2），并且被布置成传送所接收的UHF信号; vi）耦合到第一 接地平面（GP1），并布置成放大TV信号，以及vii）布置成耦合放大装置（AM）的开关装置（SM） ）到第一耦合装置（CM1）和/或第二耦合装置（CM2），以便放大装置将具有VHF和/或UHF频率的放大的所选TV信号传送到输出端。
