Publication Description :

This paper represents an Ellipse shaped patch with Ground Slotted Broadband Patch Antenna, which can be used in microwave head imaging systems. This antenna will be very simple to fabricate as it constructs with a simple patch and a ground plane. The antenna proposed is 70×60×1.5mm 3 in scale with an electrical dimension of 0.277λ×0.238λ×0.006λ at lower frequency 1.19 GHz and connected to a 50Ω microstrip feeding line. This antenna is printed onto a low-cost FR-4 substrate whose relative permittivity is 4.4, and the thickness is 1.5 mm. Here both CST and HFSS software have been used for simulation, and this comprehensive simulation exhibit that this design provides the bandwidth of 2.37 GHz (1.19 – 3.56 GHz) and 100% of fractional bandwidths (% BW) with return loss <-10 dB at the frequency of 1.19 to 3.56 GHz. This antenna on FR-4 can produce an average gain of around 3.63 dBi with 5.95 dBi peak gain at whole operation frequencies.
