UWB Antenna TOH
A planar antenna with a broadband feeding structure is presented
and analyzed for ultrawideband applications. The proposed antenna
consists of a suspended radiator fed by an n-shape microstrip feed. Study
shows that this antenna achieves an impedance bandwidth from 3.1–5.1
GHz (48%) for a reflection of coefficient and an
average gain of 7.7 dBi. Stable boresight radiation patterns are achieved
across the entire operating frequency band, by suppressing the high order
mode resonances. This design exhibits good mechanical tolerance and manufacturability....
