Abstract: This paper explores and compares two approaches to enhance the scanning rate of a series fed patch (SFP) leaky-wave antenna. In the designs, we insert into the feeding line two different ...

In this paper, a compact log-periodic dipole array (LPDA) antenna is developed at 0.5-10 GHz. This LPDA structure constitutes fewer dipole elements than a conventional LPDA antenna that exhibits ...
