Miniaturized compact super broadband printed monopole antenna

This paper introduces detailed information about a miniaturized compact super broadband printed antenna. The antenna consists of a semicircular patch, microstrip line and a partial ground plane, which is fabricated on a low cost, commercially available FR4 substrate. The overall size of the dielectric substrate is 38 × 43 × 1.5 cubic millimeter. This simple structure of the antenna has an impedance bandwidth of 1.9 to above 100 GHz. The higher operating bandwidth is achieved due to the semicircular radiating patch. The peak gain of the proposed antenna is 8.5 dB, whereas the maximum radiation efficiency is 0.75 dB. The antenna is suitable for research, military and commercial applications. The impedance bandwidth of the antenna covers applications such as 5.2/5.8 GHz WLAN bands, 5.5 GHz WiMAX bands, X band (8–12 GHz), Ku band (12–18 GHz), Ka band (26.5–40 GHz), U band (40–60 GHz), V band (50–75 GHz), W band (75–100 GHz), space and satellite communication services. Details about the gain, radiation efficiency, radiation pattern and surface current are being described in this paper.
