Triple Band Integrated Microstrip-Fed UWB Antenna for GSM, Radar and Satellite Communications

the objective of this paper is to design and analysis of the Ultra wide Band Micro strip Patch Antenna which covers the Ultra Wide Band 2.9 to 21.5 GHz. To get an optimum results and performance of the projected self complementary UWB antenna depends on the study of dissimilar methods for optimizing the different parameters of the radiating patch along with notch dimensions. The proposed self complementary UWB antenna with overlapped rectangular shape patch and Defected DGS is designed with C-Slot in the radiating patch element and ground with L shaped slot which covers the whole UWB frequency band apart from band notches WLAN (5.125-5.825 GHz) ,Satellite Communications (7.9-8.5 GHz) and Ku band 13.4-14.5GHz.The UWB antenna performance is improved in terms of the Bandwidth by including Rectangular shaped slit between feeding element and the radiating patch. Now a days it is important to avoid existing wireless communication networks from the design of UWB antenna. The self complementary UWB antenna impedance bandwidth from 2.9 GHz to 21.5 GHz with a maximum of return loss S11 -43 dB at operating frequency10.5 GHz and with a Gain of 5.64dB.

Abstract A compact ultrawideband (UWB) antenna with reconfigurable triple band notch characteristics is proposed in this paper. The antenna consists of a coplanar waveguide-fed top-cut circular-shaped radiator with two etched C-shaped slots, a pair of split-ring resonators (SRRs) on the backside and four p-type intrinsic n-type (PIN) diodes integrated in the slots and SRRs. By controlling the current distribution in the slots and SRRs, the antenna can realize eight band notch states with independent switch ability, which allows UWB to coexist with 5G (3.3–4.4 GHz)/WiMAX (3.3–3.6 GHz), WLAN (5.15–5.825 GHz), and X-band (7.9–8.4 GHz) bands without interference. By utilizing a nested structure of C-shaped slots and SRRs on the backside, a compact size of 18 × 19.5 mm2 is achieved along with multimode triple band notch reconfigurability. The antenna covers a bandwidth of 3.1–10.6 GHz. A prototype is fabricated and tested. The simulated and experimental results are in good agreement.
