The dual V-type linearly tapered slot antenna (DVLTSA) is a modified version of the Vivaldi radiator and is first introduced here. It is much more compact and keeps the advantages of the conventional tapered slot antenna (TSA). Furthermore, this antenna is suitable for a monopulse antenna owing to i...

In our paper, an inset-fed microstrip patch antenna has been designed and the dependency of resonant frequency on the notch gap and the feed line geometry has been studied. Our study suggests that a narrower notch resulted in better impedance matching. A design rule has also been formulated and pres...

A top-wall substrate integrated waveguide (SIW) slot radiator for generating circular polarized (CP) field is proposed and characterized in this letter. The reflection of the slot radiator is extremely weak, which simplifies the linear traveling wave array design. Based on such a structure, a 16-ele...
