A microstrip-fed slot antenna is proposed for short-range UWB communication. First, the characteristics of a conventional 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.

“…In this scheme, we have connected a diode and a resistance R at the input. Only one pulse was achieved in the output corresponding to the falling edge of the input pulse as has already been described in [17], and further details are omitted. A number of microstrip line sections are shown in Fig.…”

Abstract-In this paper, the design and development of a novel active antenna including circuits for Ultra-wide band (UWB) pulse generation and transmission have been described. In this design a pulse with pulse-width approximately 150 ps and amplitude 500 mV (peak-topeak) was generated using a single high electron mobility transistor (HEMT) as the active device (and an optional Schottky diode for enhanced performance), this being the simplest circuit for generating UWB pulses as far as we know. This circuit was integrated with a newly designed UWB planar microstrip-fed slot antenna, which is an active antenna in the sense that in addition to radiating the signal, it also acts as a filter, which tailors the spectrum of the transmitted pulse to a shape close to that recommended for UWB communications. We have also given a quantitative analysis, which explains the operation of the circuit.
