Entwurfskonzept einer Car2Car-Multiband-Dachantenne

[摘要] Due to the vastly increasing use of wireless services in the car, such asWiFi, Car2Car and LTE, the requirements on bandwidth and radiation pattern ofthe roof antenna systems become more challenging. In this work, a designconcept for multi-band roof antenna systems is presented. We aim to get ahigher bandwidth and an almost circular radiation pattern on the horizontalplane. Moreover, the antenna length is considered in order to fulfill therequirements set by construction ECE-regulations (ECE, 2010). Theapplicability of the design concept is not limited to multi-band roofantennas, it can also be used for a general wideband antenna design. Forillustration of this concept, a multi-band roof antenna with a bandwidth of780 MHz to 5.9 GHz and a near circularradiation pattern with an average gain ofG = 3 dBi (at 5.9 GHz) on thehorizontal plane is designed. The simulation and measurement results arepresented.
