Thus, wideband reduction of RCS is obtained from 4 to 9.5 GHz and changes in antenna pattern, gain, and impedance bandwidth in comparison with the ones of conventional patch array antenna are negligible. It is shown that simulation and measurement results are in good agreement with each other....
A wideband switched beam patch antenna array for LTE and Wi-Fi In this paper a Switched beam 4×1 linear antenna array is presented with a 4×4 Butler matrix feed. For wideband operation Aperture coupled antenna elemen... M Fernandes,A Bhandare,C Dessai,... - India Conference 被引量: ...
A circular polarization (CP) and mode reconfigurable wideband orbital angular momentum (OAM) patch array antenna is presented. The proposed design is based on a reconfigurable feed network (RFN), a direct current (dc) bias circuit, and a $2 imes 2$ patch array. By changing the dc bias vol...
The dimensions of the S-UWB patch antenna are 27 mm 脳 27 mm 脳 1.1 mm. This antenna was designed and simulated to verify the results of the measurements. The S-UWB has been simulated with a mathematical software to obtain the possible results....
A compact and simple patch antenna for ultra high frequency band is current demand for RFID tag. By em- bedding a pair of symmetrical key-shaped slot near the non-radiating edge of the rectangular patch, a new adjacent resonant mode close to the fundamental mode is excited to form a wide...
In this paper, a substrate integrated waveguide (SIW)-based wideband circularly polarized (CP) 4×4 patch array antenna operating in 45 GHz band is proposed. Firstly, a series-fed 1×4 patch subarray is designed. Sequential rotation (SR) feeding technology is adopted to extend axial-ratio (...
A wide bandwidth and wide beamwidth L-probe-fed patch antenna array with a novel design of grounded structure is proposed and tested. The antenna is made o... TP Wong,KM Luk 被引量: 0发表: 0年 Multi-Slotted Microstrip Patch Antenna for Wireless Communication A new design technique of micr...
wideband patch antenna design hello, I have to design a patch antenna with 25% bandwidth. I would like to use stacked patches (possibly two) with coax feed, can anyone suggest some design rules or design formulas to start with, instead of leaving everything to the optimiser of any EM ...
including the use of stacked patches18, a U-slot patch19or an L-shaped probe feed20, the radiation characteristics of the antenna vary substantially over the operating bandwidth. The same difficulty is also encountered in designing wideband reflector-backed dipole arrays21or cavity-backed slot arra...
A wideband patch antenna is presented that comprises a patch which may be of pure metallic form or may be etched on a dielectric, that may be rectangular, elliptical, triangular, or any other geometric shape. The patch is disposed a distance above a ground plane and is driven by a helix-...
