Abstract:
A microstrip-fed slot antenna is proposed for short-range UWB communication. First, the characteristics of a circular monopole UWB antenna, as a representative of a class of UWB antennas seen in the literature, are examined in time (pulse-shape) and frequency (reflection and transmission coefficients) domains. From these measurements, certain limitations of this class of antennas are brought out, which are not widely recognized. We then demonstrate that with proper optimization the traditional microstrip-fed slot antenna overcomes these defects and is an excellent candidate for UWB communication systems. This claim is justified with measurements in time domain and frequency domain.
