A new type of dual-polarization and dual-frequency multilayer-stacked microstrip array antenna is introduced. The feeding mechanism of the element is the aperture coupling for one polarization and the direct feeding for the orthogonal polarization. The microstrip element exhibits a wideband of operation. A slot etched on driven patch is used to improve isolation performance of the proposed antenna...
A novel textile two-element array antenna with special structure at 1.5GHz is introduced. The patches, the substrate and the ground are woven together as a unity. The measured results agree well with the simulated ones, and the measured gain is 6.4dB, showing the usability of the new generation of textile antennas.
A novel textile array antenna with special structure at 1.54GHz is introduced. The patch, the substrate and the ground are woven together as a unity. Measured results are compared with the simulated, showing the usefulness of new generation of textile antenna.
A hybrid-fed dual-polarized stacked patch element with low cross-polarization and high port isolation is introduced. The proposed antenna element achieves a 10 dB return loss bandwidth of 840 MHz (about 15%) in C band. The crosspolarization of antenna keeps under -37 dB in both orthogonal ports with the isolation remains less than -42 dB in the whole bandwidth. The front-back ratio of radiation pattern...
In this paper, a 4 times3 elements coplanar feed array is designed to obtain narrower beam width, higher gain and to optimize the feed network for low-sidelobe level in the horizontal plane. In order to achieve the low-sidelobe and narrow beamwidth characteristics, the array was synthesized by means of Chebyshev distribution in the horizontal direction and equal distribution in the vertical direction...
