Microstrip-Fed Ring Slot Antenna Design With Wideband Harmonic ...
2014年6月12日 · A microstrip-fed circular ring slot antenna (CRSA) with a fundamental mode at 2.45 GHz is initially studied. To suppress the additional harmonic modes excited by the ring slot, a single inverted U-shaped slot (or defected ground structure, DGS) is integrated into the CRSA.
Design, simulation, and fabrication of a double annular ring microstrip ...
2022年5月1日 · A novel double annular-ring microstrip antenna, split into six sectors, is proposed to achieve multiband operation with high gain and impedance bandwidth. The gaps on the driven and parasitic patches excite resonant frequencies that are located in the Ku-, K-, and Ka-bands thus making the antenna capable of these multiband applications.
MicroStrip Line Feed is used to excite the Annular Ring Patch Antenna placed on an FR4 substrate (dielectric constant εr = 4). The proposed antenna is suitable for S, C and X band wireless communication system. The antenna shows four bands at f1 = 2.96 GHz, f2 = 5.57 GHz, f3 = 7.91 GHz and f4 = 10.57 GHz respectively in S, C and X bands.
Multifrequency operation of microstrip-fed slot-ring antennas …
Operating frequencies and radiation patterns of microstrip-fed ring slot antennas are investigated. The microstrip feed is shown to strongly affect the operating frequencies of the slot antenna. As the length of the microstrip stub is increased to exceed half the guided wavelength of the first operating frequency, then multiple operating ...
