Planar Finger-Shaped Antenna Used in Ultra-Wideband Wireless Systems
Abstract: Recently, extensive
requirements have developed for ultra-wideband (UWB) technology that provides
high activity and small size for use in small communication systems, remote
sensing, and radar applications. Thus, we concentrated with high-resolution
radar UWB antenna to cover Federal Communication Commission’s (FCC) standard
UWB range (3.1-10.6 GHz). The proposed ideal-size and low-cost finger-shaped
patch antenna of 24 mm x 19 mm printed on 40 mm x 35 mm rectangular Taconic TLY-5
material was designed and established through experiments and simulations.
Results show that the two cut notches of 1.5 mm x 2 mm at the bottom corners of
the patch can increase the bandwidth. To increase the radiation area and
achieve more resonance frequencies, two cut slots at the top edge of the patch
were designed in depth of 10 mm. Four parameters were considered in the
analysis of the proposed antenna design, namely the feeder width, number of
slots, number of notches, and feed gap space. The simulated and measured
results of the main antenna parameters make the design suitable in applications
of UWB wireless systems.
