“…In this research, the proposed UWB parasitic array structure which is combined with coaxial feed even recorded the maximum gain up to 9.4 dB. This is due to less loss of signals occurs for coaxial feeding method as it involves shorter transmission lines where the signal is directly fed to the radiating patch . Coaxial feed also exhibit better result in term of return loss compared with strip line feed .…”

A high performance of coaxial feed ultrawide band (UWB) array antenna with parasitic element is proposed in this article. The 4 × 1 array antenna consists of four identical copper circular patches are appropriately connected using quarter‐wavelength transformer transmission line. The array elements and its feed network are properly optimized to have a high‐gain performance over wide range bandwidth frequencies. Introduction of semicomplementary copper parasitic element with copper partial ground technique are applied in this proposed antenna to obtain optimum large bandwidth. Taconic associated with 2.2 dielectric constant and thickness of 1.6 mm is used as the antenna substrate. Less complicated fabrication methods is possible due to the feeding network placement is on the same level with the antenna patch elements. The performance of the designed antenna evaluated in term of return loss, bandwidth, radiation pattern, directivity, and gain. The proposed antenna recorded reflection coefficient less than −10 dB started from 2.5 to 12.6 GHz which fulfilling the requirement of UWB. Dimensions of 80 × 45 mm2 and maximum gain of 12.12 dB made it as small and high gain UWB antenna. The antenna exhibits a stable gain from 3.4 to 12.12 dB over the operated frequencies and has 83% of usable fractional bandwidth. The proposed antenna performance finds it very suitable to be applied in human brain microwave imaging. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:649–653, 2015

A new design of compact Super Wideband (SWB) antenna for performance comparison between in free space and in plain water is presented in this paper. The proposed antenna consists of basic circular patch as radiating element associated with partial ground and a zinc reflector to realize high gain and wide bandwidth. Dimension of 20 mm × 30 mm made the proposed antenna as a compact antenna. The significant feature of this design is the cautious manufacturing of the feed line with additional of two microstrip lines between the patch and the feed line known as stepped transmission line that altering the capacitance between the radiating element and the ground plane. The patch is directly connected with SMA connector using 50 Ohm mirostrip feed line through side feeding and deploy the air gap stacked. The antenna exhibit high performance in free space indicated by operated frequency ranged from 4.3 GHz until more than 15 GHz (<-10dB) with maximum gain of 9.79 dB. On the other hand, plain water medium degraded the antenna performance yet still within acceptance limit associated with resonant frequency ranged from 4.7 GHz until more than 15 GHz (<-6dB) and 2.2 dB for the maximum gain. The results reflect the reliability of the SWB antenna operated within liquid medium for various related applications especially for biomedical related applications such as microwave imaging for cancer detection.
