A supper-broadband antenna structure designed with a specific coplanar waveguide (CPW) mode to make its covering range of frequency be in a range of about 300 MHz˜9 GHz., of which the covering range of frequency is in a range of 300 MHz˜9 GHz having a rational efficiency of above 40% within the range of frequency band, and the return loss is better than the value −5 dB. The structure of a single supper-broadband antenna designed according to the present invention can be applied to many usages easily and accurately, e.g., for checking chamber stability, chamber to chamber verification etc. |
