Compact Micro Strip Fed Koch Fractal Monopole Loop Antenna For Multiband Performance

摘要

A compact Koch fractal monopole loop antenna with $50{Omega}$ micro strip feed for multiband application is presented. The proposed antenna is designed on duroid 5880 substrate with the dimensions of Lsub 57 mm x Wsub x 49 mm x h 1.6 mm with the ground slit of dimensions L1 5.5 mm x W1 4.92 mm and 1.62 GHz - 2.53 GHz (910MHz), 4.72 GHz - 6GHz (1280MHz) and 8.4 GHz - 10.45 GHz 2050MHz suitable for DCS/PCS/UMTS, IEEE 802.11, Radio navigation respectively. The proposed antenna exhibits good return loss in the simulation and the symmetrical geometric structure of the antenna provides Omni directional radiation patterns.
