compact antenna array with the ability to scan over a larger angle. 2. Proposed Slot Antenna for Antenna Arrays The reference array antenna is a 1 2 arrangement of rectangular microstrip patches, as shown in Figure1a. Standard patch design was used to implement it … US6806839B2 - Wide bandwidth flat panel antenna array A cavity-backed wideband slimline flat panel antenna array for providing a steerable beam includes an array of slot antennas, each of which fed by its own individual dipole radiator, with the wide bandwidth being due to the matching impedances of the slot antenna and dipole radiator across the entire frequency band. In one embodiment, an upstanding printed circuit balun feed is connected to Wideband Shorted Patch Antenna With a Modified Half U-Slot
Wide-Angle X-Band Antenna Array with Novel Radiating Elements. Roman CHERNOBROVKIN.An antenna array with wide-angle beam steering is presented in this paper.The waveguide excita-tion is realized by means of a long coaxial transmission.
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. Wide-Band Slot Antenna Arrays With Single-Layer Corporate The paper describes two test antennas: a 4 × 1 linear slot array and a 2 × 2 planar slot array. Both have been fabricated and tested at Ku- band. The linear array shows more than 20% bandwidth and the 2 × 2 array shows a bandwidth of 21% for 10-dB return loss. There are good agreements between measured and simulated patterns for both antennas. A low profile 10:1 (200–2000 MHz) wide band long slot array 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
