Abstract
An improved antenna arrangement, in particular for motor vehicles having at least two antenna devices, has at least one first antenna element for the mobile radio range and at least one second antenna element. The second antenna element is intended for a different service than the mobile radio range. The lateral distance between the at least one antenna element which is provided for the first antenna arrangement and the antenna element for the second antenna arrangement has at least sections which are <λ/8, where λ represents the wavelength of the mobile radio antenna.
Claims18
A vehicular antenna arrangement, for operating at least on a mobile radio frequency range, comprising:
- at least one first antenna element for the mobile radio frequency range;
- and
- at least one second antenna element for a different service than the mobile radio frequency range, the lateral distance between the at least one first antenna element and the at least one second antenna element having at least sections which are <λ/8 wherein the at least one first antenna element comprises plural antenna elements for reception in different frequency bands offset with respect to one another, and wherein the distance between the at least one second antenna element and an immediately adjacent one of said plural first antenna elements is <λ/8, where λ is the wavelength in an upper frequency band of the plural first antenna elements provided for the mobile radio frequency range.
An antenna arrangement for operating at least on a mobile radio frequency range, comprising:
- at least one first antenna element operating at a wavelength λ for the mobile radio frequency range;
- and
- at least one second antenna element for a different service then the mobile radio frequency range, the lateral distance between the at least one first antenna element and the at least one second antenna element has at least sections which are <λ/8, wherein the at least one second antenna element defines a double angle, such that the feed point of the second antenna element is further away from the at least one first antenna element than an antenna section which is offset with respect to the feed point of the second antenna element, wherein the at least one first antenna element comprises plural antenna elements for reception in different frequency bands offset with respect to one another.
The antenna arrangement for operating at least on a mobile radio frequency range, comprising:
- at least one first antenna element operating at a wavelength λ for the mobile radio frequency range;
- and
- at least one second antenna element for a different service than the mobile radio frequency range, the lateral distance between the at least one first antenna element and the at least one second antenna element having at least sections which are <λ/8, and further comprising a further antenna section which runs at an angle to the at least one first antenna element, wherein the at least one first antenna element comprises plural antenna elements for reception in different frequency bands offset with respect to one another.
An antenna arrangement for operating at least on a mobile radio frequency range, comprising:
- at least one first antenna element operating at a wavelength λ for the mobile radio frequency range;
- and
- at least one second antenna element for a different service than the mobile radio frequency range, the lateral distance between the at least one first antenna element and the at least one second antenna element having at least sections which are <λ/8, wherein the at least one first antenna element comprises plural antenna elements and wherein the at least one second antenna element is for DAB reception and is arranged between said plural antenna elements.
An antenna arrangement for operating at least on a mobile radio frequency range, comprising:
- at least one frequency antenna element operating at a wavelength λ for the mobile radio frequency range;
- and
- at least one second antenna element for a different service than the mobile radio frequency range, the lateral distance between the at least one first antenna element and the at least one second antenna element having at least sections which are <λ/8, further comprising a matching circuit coupled to at least one of said first and second antenna elements.
