Abstract
This paper depicts a wideband Square Enclosed Circle (SEC) microstrip patch antenna for the head imaging system. The antenna proposed contains a Square Enclosed Circle central radiating-patch and a slotted partial corner cut ground. Slots are used fur improving efficiency, gain and radiation directivity. The optimized electrical dimension at the first resonance frequency of 1.9 GHx is 0.253λx0.190λx0.010λ The antenna is installed on FR-I substrates with 1.5 mm thickness that are inexpensive. 50-® impedance matching microstrip-transmission line was being used to feed the antenna. The analyzed findings show that the described prototype has a L9 GHz (L9-3.8 GHz) bandwidth with omnidirectional radiation properties. The antenna mentioned attains a max gain of 3.54 dBi at 3.78 G and maximum radiation efficiency of 87.77% over the frequency band. Specific design mechanisms are applied to get much more relevant results. The antenna proposed is altered, developed and evaluated throughout the popular simulator-software CST Microwave Studio 2019.
