Definitions
- the invention relates to a radio in the preamble of Claim 1 described Art.
- the rod antennas of compact radio devices should be avoided usually retractable or retractable. If in this condition the device should remain ready for operation (standby mode) in addition to the rod antenna (main antenna) in the Device integrated antenna (auxiliary antenna) may be provided because the recessed or folded main antenna electrically strong out of tune and at least partially shielded and therefore unusable is.
- Known solutions with integrated antenna have the disadvantage that the latter function as the main antenna interferes by depriving her of energy. Conversely bothers the main antenna the function of the integrated auxiliary antenna, when it is sunk.
- Another disadvantage is in that the integrated auxiliary antenna is a not insignificant Installation volume required.
- the retractable Arrange the rod antenna so that its function is recessed or folded over at least partially preserved remains by making sure that it retracted or folded down not nearby electrical conductive structures.
- An adjustable antenna arrangement is known from US-A-4 121 218 known for a portable radio with an extendable Half-wave dipole that is capacitively coupled to one coiled antenna (helix), the helix being fed from the end.
- the dipole can be adjacent or collinear with the axis the helix antenna.
- the upper part of the rod antenna consists of insulating material, so that the helix when the rod antenna is sunk is not disturbed.
- US-A-4 868 576 describes a telescopic antenna for a portable cellular phone, the antenna being a quarter-wave fundamental and includes a coiled coil the capacitive to an extendable half-wavelength radiator is coupled.
- the extendable half-wavelength radiator contains a metal coil embedded in plastic; the basic radiator contains a winding transmission line on a flexible circuit board. The coiled The coil and the basic radiator are via a transmission line connected to a duplexer.
- US-A-43 087 117 is a portable transmitter known with selective antenna elements. This radio is small with a size normally used built-in antenna and a pull-out antenna for one larger radio range provided that with extended antenna is switched on automatically.
- the invention has for its object the foregoing eliminate the disadvantages listed and a compact radio to create with integrated auxiliary antenna, which with sunken stand-by mode enables the mutual interference of Auxiliary antenna and rod antenna should be as small as possible.
- the handheld radio shown in Figures 1 and 2, the total denoted by 1 has a function as the main antenna Rod antenna 2, at the foot of which there is a feed part 3 is located.
- the upper end area of the antenna 2 is made from an insulating part 4.
- the antenna 2 can with its Feed part 3 in a provided in the handheld radio 1 Recording room 5 are sunk.
- This recording room 5 ends with its upper end in a conical housing approach 6, which is made of plastic.
- This conical Approach 6 is hollow, so that the feed part 3 of the antenna 2nd is included in it when the antenna 2 is pulled out completely is.
- the feed point of the integrated antenna 7 is designated 8.
