FREQUENCY-DOMAIN AND TIME-DOMAIN RESPONSE SHAPING FOR ULTRA-WIDE BAND ANTENNAS


Razvan D. TAMAS1

Abstract.  This paper presents a synthesis approach for ultra-wide band (UWB) antennas, based on a variable slope profile. When applying the proposed approach in the timedomain, one can synthesize antenna structures for pulsed excitation, designed to yield a low distortion response at a given direction or within a given plane and for a given polarization. The method is validated by synthesizing ultra-wide band antennas designed for a particular waveform of excitation. The applicability of our method to frequencydomain synthesis is demonstrated by designing an antenna with a quasi-linear gain variation over a given frequency range. The antenna configuration resulting from synthesis was simulated, manufactured and measured in order to validate our method. Keywords: Ultra-wide band antennas, frequency-domain response shaping, time-domain response shaping, variable slope profile
