A suspended microstripline‐fed linear tapered slot antenna element and its E‐plane linear arrays are presented in this paper. The element is studied and designed using the finite‐difference time‐domain (FDTD) method. The simulated results show that the element has a good antenna performance from 17 to 24 GHz. To build the E‐plane arrays, a unique five‐piece assembled structure which guarantees a uniform air‐filled thin substrate in the suspended microstrip line parallel feed‐network, has been developed. Four E‐plane arrays with different numbers of elements (4, 8, 16, and 32) are fabricated and their antenna gains and patterns are examined experimentally. © 2004 Wiley Periodicals, Inc.
