L-Slots Square Antenna for Octa-band Applications
The objective of this paper is to design an Octa- Band L-slot Square Patch antenna which will operate in 3.18 GHz, 4.71 GHz, 7.04 GHz, 8.38 GHz, 8.86 GHz, 10.66 GHz, 11.76 GHz, 14.12 GHz frequencies. The same antenna would also work in UWB frequencies. An L-slots Square copper patch with a thickness 0.035mm is placed on FR4 epoxy substrate having dielectric constant 4.4 with a height of 1.6 mm with single port. This has been designed using HFSS commercial software simulator so that Return Loss, VSWR, Radiation pattern and Surface current distribution can be measured.
