Abstract
In this paper, an Ultra-Wideband (UWB) planar antenna is proposed for the reinforced concrete detection, which consists of a pair of planar waterdrop arms, a microstrip to coplanar parallel-strips transition and a shallow rectangular cavity. In order to overcome the disadvantages of the shallow cavity, some absorbing material is loaded to weaken the narrow-band effect of the cavity and the crosstalk interference. The simulated and measured results show that the proposed antenna has a large bandwidth from 0.48 GHz to 3.6 GHz with Voltage Standing Wave Ratio (VSWR) below 2 and a fractional bandwidth about 200% under the center frequency of 1.6 GHz, directional radiation characteristics and small late-time ringing in the time domain, which can be suitable for nondestructive detection of the reinforced concrete.
