Antenna

Abstract

The disclosure relates to an antenna comprising: a substrate; a conductor pattern on the substrate, wherein the conductor pattern comprises first and second conductor areas, wherein the first conductor area is generally at a first end of the substrate and the second conductor area is generally at an opposing second end of the substrate, wherein a first direction extends between the first and second ends of the substrate; wherein the first conductor area has two arms, the two first conductor area arms extend parallel to the first direction and define a first slot between them; wherein the second conductor area has two arms with a second slot defined between them, and the two second conductor area arms extend parallel to the first direction, wherein the two second conductor area arms sit within the first slot with a portion of the first slot at the outer sides of the two second conductor area arms, wherein the second conductor area has a third arm extending parallel to the first direction but opposite to the two other second conductor arms; a first feeding port which bridges an end of one of the two second conductor area arms and a base of the first slot; and a second feeding port which bridges an end of the other of the two second conductor area arms and the base of the first slot; and a third feeding port for the second conductor area.

Description

technical field [0001] The present invention relates to an antenna, in particular but not exclusively, to an antenna for car-to-multiple application (car-to-X, C2X) communication. Background technique [0002] C2X communication is considered as a key technology to facilitate safe and intelligent mobility in the future. The C2X communication link is made up of various components, of which the antenna is the subject of the present invention. [0003] Today's vehicles are equipped with many wireless services to receive radio and television broadcasts, and support communication devices such as mobile phones and GPS navigation. Even more communication systems will be implemented for "smart driving", such as Wireless Access in Vehicle Environment (WAVE), in-vehicle communication systems. As a result, the number of automotive antennas is increasing, and miniaturization requirements are becoming an important factor for cost reduction. [0004] The inter-vehicle communication syst...

AI Technical Summary

Problems solved by technology

The difficulty with this type of antenna arrangement is that the first and second antenna elements usually interfere with each other and thus create a non-uniform radiation pattern
