“…For the above three electrical small antennas, the time delays of fields emitted by antennas are small and usually can be ignored unless the ultra-precise position measurement is required. The time domain simulation waveform of the above three antennas is in excellent agreement with measured results [33][34][35] and, therefore, will be included in our pulse generator design and simulation. Please note that an antenna model is an approximation of the antenna.…”

“…From the circuit perspective, an antenna can be thought of as a lossy one-port network and the power dissipated in the network is equal to the antenna radiated power. On the basis of this principle, Wang and Gerrits gave equivalent circuit models for dipole, monopole and large current radiation (LCR) antennas for low-frequency band UWB applications [32][33][34][35]. Although their circuit diagrams are different, they both use a radiation resistor R rad to represent the radiated signal from the antenna.…”

SUMMARYGaussian pulse is widely used in communication systems. The true Gaussian function is not physically realizable, but it can be approximated through linear functions. This paper presents a Gaussian pulse approximation approach to generate a quasi-Gaussian pulse by using the transient response of a CMOS inverter. The basic structure of the proposed design includes a digital variable square pulse generator, a Gaussian pulse generator and a small antenna model. The digital variable square pulse generator makes the amplitude and width of the generated quasi-Gaussian pulse tunable. The proposed pulse generator works well for three different electrical small antenna models. The simulation results show that the generated pulse approximates the Gaussian shape very well and the radiated signal at the antennas is compliant with the Federal Communication Commission's spectral mask for the 0-960 MHz band. The simple structure of this Gaussian pulse generator lends itself to a low-power, single-chip UWB transceiver solution.

“…A different approach was applied in [2] where an equivalent circuit containing more poles was adopted and the component values were fit by genetic algorithms. In [3], a broadband monopole antenna was fit by a physic-based equivalent circuit containing a transmission line and the component values were determined empirically. However, all the above methods are restricted by the simplicity of the physics-based circuits and cannot fit a wide range of frequency responses under a user-specified error bound.…”
