Fractal technology has great potential in antenna miniaturization, multi-frequency, ultra-wideband application, and this paper are about fractal technology in the application of multi-frequency microstrip antenna. Based on the fractal structure design of Sierpinski, we studied the multirate characteristics of nested triangle fractal monopole antenna, using electromagnetic field simulation software...
Two novel CPW-fed disc antennas etched with C-like slots are proposed with the impedance bandwidths ratio (VSWR ≤ 2) are 10.6:1 and 12.6:1. The antennas are successfully simulated, designed, and measured, showing the advantages of super wide band, stable gain and omni-directional radiation patterns. They are compact dimension and single-sided, can be easily integrated with monolithic microwave integrated...
In this letter, a patch antenna with folded arrowhead-shaped structure is proposed to extend impedance bandwidth, decrease size and enhance gain. The antenna is optimized, fabricated and measured. The measured results indicate that an impedance bandwidth of 85% with Sll<;-10 dB (5.1 GHz to 12.6 GHz) is obtained and the antenna gain fluctuates from 4.4 dBi to 6.6 dBi over the whole bandwidth. The...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
