Abstract
A linear‐tapered slot antenna (LTSA) element fed by a novel suspended microstripline (SML) feed structure is presented in this article. The element is designed using the finite‐difference time‐domain (FDTD) method. It shows that the element has a wide impedance bandwidth in K‐band. Using the new element, a 4 × 4 SML parallel‐feed array has been designed and built. The measured results demonstrate that the array matches its 50‐ohm SML feed line in a wide frequency band, has better than 16 dBi gain from 17.7 to 23.3 GHz, and has low cross polarizations in both the E‐ and H‐plane. © 2009 Wiley Periodicals, Inc.
