A low profile 10:1 (200–2000 MHz) wide band long slot array ... Abstract: A low profile 10:1 band (200-2000 MHz) long slot array was developed for radar and EW applications. For performance demonstration, a prototype array of 11times11 elements (1.2 m times 1.2 m) was built and tested. It is backed by a ferrite loaded A NOVEL WIDEBAND ANTENNA ARRAY WITH TIGHTLY COUPLED OCTAGONAL ... Although wideband phased array design is a long-standing topic of interest, progress has recently been made using endflre tapered slot antennas. The stripline fed tapered slot antenna, often called Vivaldi antenna, was flrstly introduced by Lewis etal. in 1974, and A Design of Wide Band and Wide Beam Cavity-Backed Slot ... In this paper, a design of wide band and wide beam cavity-backed slot antenna array with the slant polarization is proposed. To obtain wide band and wide beam with limited size, the inverted microstrip-fed cavity-backed slot antenna (IMF-CBSA) is adopted as the

WIDEBAND SLOT AND PRINTED ANTENNAS ATEF Z. ELSHERBENI ABDELNASSER A. ELDEK CHARLES E. SMITH Center of Applied Electromagnetic Systems Research (CAESR) The University of Mississippi University, Mississippi 1. INTRODUCTION Wideband antenna elements are essential for providing wideband scanning array antennas in industry and mili-tary applications. Wideband RCS Reduction of a Slot Array Antenna Using Phase ... Abstract: In this letter, a slot array antenna loaded with a phase gradient metasurface (PGM) for a monostatic radar cross-section (RCS) reduction is presented. The PGM, which has stable a phase gradient and a 2π-phase variation range in a wide operating bandwidth, is placed over the slot array antenna. A low profile 10:1 (200–2000 MHz) wide band long slot array The antenna is ultra thin, with a total thickness of 8 cm including the ferrite tiles, about 5% of the wave length at 200 MHz. On average, the array has 2 dB loss over the 10:1 band. The antenna is designed for airborne missions that require very wide band and ultra-thin profile.

(PDF) Meander-slot and U-slot antenna arrays for wide-… Narrow-band resonant rectangular slot antennas used in earlier designs are replaced by meander- slot antennas and their modifications, in order to increase the frequency bandwidth and efficiency of the system. Numerical results for finite arrays of meander-slot and U-slot antennas show significant... Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. Broadband array antenna Stick Array (16 short, 8 long required for array). 3.5 Test Set-up. The initial concept for testing of both the 3:1 array and the 9:1 array was the same.[4] Tan-Huat Chio and D.H.
