Planar antenna structure and radio device |
| abstract |
A planar antenna structure intended to be used in small portable radio devices and anradio device using an antenna structure according to the invention. The radiatingnelement (340) of the antenna is a conductive part in the cover of the radio device orna conductive coating attached to the cover. The radiating element is fed electromagneticallynby a parallel planar feed element (330) connected to the antenna portnand located near the radiating element, between it and the ground plane (310).nBetween the feed element and antenna port there is a feed circuit (320) to providenmatching for the antenna and, if necessary, forming an additional operating band.nThe radiating element need not be shaped to set the resonating frequencies or matchnthe antenna. Instead, it can be designed relatively freely, based on the desirednexternal appearance of the device, for example. Moreover the antenna requiresnrelatively little space within the device. |
