| Summary: | Due to the vastly increasing use of wireless services in the car, such as
WiFi, Car2Car and LTE, the requirements on bandwidth and radiation pattern of
the roof antenna systems become more challenging. In this work, a design
concept for multi-band roof antenna systems is presented. We aim to get a
higher bandwidth and an almost circular radiation pattern on the horizontal
plane. Moreover, the antenna length is considered in order to fulfill the
requirements set by construction ECE-regulations (ECE, 2010). The
applicability of the design concept is not limited to multi-band roof
antennas, it can also be used for a general wideband antenna design. For
illustration of this concept, a multi-band roof antenna with a bandwidth of
780 MHz to 5.9 GHz and a near circular
radiation pattern with an average gain of
<i>G</i> = 3 dBi (at 5.9 GHz) on the
horizontal plane is designed. The simulation and measurement results are
presented. |
