Claims (7)

1. Радиотелефон, предпочтительно, для сотовой связи, содержащий корпус устройства, по меньшей мере, одну антенну (21), которая крепится к или находится в соединении с корпусом устройства, для беспроводной связи радиотелефона посредством передачи и приема электромагнитных радиоволн в заданном диапазоне длин волн, отличающийся тем, что содержит средство уменьшения токов (30, 31), размещенное в корпусе устройства (20) между антенной 21 и стороной (23) радиотелефона, которая при нормальном использовании обращена к пользователю (1), причем указанное средство имеет проводящие, а также диэлектрические свойства и размещено для уменьшения или исключения электрических токов, имеющих место в и/или на корпусе устройства (20) между антенной (21) и стороной (23) радиотелефона.1. A radiotelephone, preferably for cellular communication, comprising a device body, at least one antenna (21) that is attached to or connected to a device body for wireless communication of a radiotelephone by transmitting and receiving electromagnetic radio waves in a predetermined wavelength range characterized in that it comprises means for reducing currents (30, 31), located in the device body (20) between the antenna 21 and the side (23) of the radiotelephone, which, in normal use, faces the user (1), wherein GUSTs has conductive and dielectric properties and taken to reduce or eliminate electric currents present in and / or on the housing device (20) between the antenna (21) and side (23) of the radiotelephone. 2. Радиотелефон по п.1, отличающийся тем, что средство уменьшения токов является четвертьволновой пластиной (30, 31). 2. The radiotelephone according to claim 1, characterized in that the means for reducing currents is a quarter-wave plate (30, 31). 3. Радиотелефон по п.2, отличающийся тем, что четвертьволновая пластина содержит металлический элемент (30) с по существу L-образным поперечным сечением, причем между верхней частью металлического элемента 30 и лежащими ниже частями корпуса устройства (20) образована щель. 3. A radiotelephone according to claim 2, characterized in that the quarter-wave plate contains a metal element (30) with a substantially L-shaped cross section, and a gap is formed between the upper part of the metal element 30 and the lower parts of the device body (20). 4. Радиотелефон по п.3, отличающийся тем, что в щели размещен диэлектрический элемент (31). 4. The radiotelephone according to claim 3, characterized in that a dielectric element (31) is placed in the slit. 5. Радиотелефон по п.4, отличающийся тем, что длина металлического элемента (30) и значение диэлектрически постоянной εr диэлектрического элемента (31) выбираются так, чтобы удовлетворить выражению
Figure 00000001

где λ - длина волны.5. The radiotelephone according to claim 4, characterized in that the length of the metal element (30) and the value of the dielectric constant ε r of the dielectric element (31) are selected so as to satisfy the expression
Figure 00000001

where λ is the wavelength. 6. Радиотелефон по любому из пп.1 - 5, отличающийся тем, что его сторона (23), обращенная к пользователю (1), покрыта слоем (32) материала, который способен уменьшить электрические токи, имеющие место в и/или на корпусе устройства. 6. A radiotelephone according to any one of claims 1 to 5, characterized in that its side (23) facing the user (1) is covered with a layer (32) of material that is able to reduce electric currents occurring in and / or on the housing devices. 7. Радиотелефон по любому из пп.1 - 6, отличающийся тем, что содержит громкоговоритель (24) и микрофон (25), которые размещены на первой удлиненной стороне (23) радиотелефона; антенну (21), которая размещена на противоположной второй удлиненной стороне с верхней стороны или нижней стороны радиотелефона; а также дисплей (26) и клавиатуру (27), которые размещены на другой стороне, предпочтительно на передней стороне, отличной от упомянутых сторон радиотелефона. 7. A radiotelephone according to any one of claims 1 to 6, characterized in that it comprises a loudspeaker (24) and a microphone (25), which are located on the first elongated side (23) of the radiotelephone; an antenna (21), which is located on the opposite second elongated side of the upper side or lower side of the radiotelephone; as well as a display (26) and a keyboard (27), which are located on the other side, preferably on the front side, different from the mentioned sides of the radiotelephone.
