Firstly, people increasingly high demand for the wireless transmission rate and UWB properties such as high data rate, low power. The receiver combines a ring slot antenna SIS mixer with a twin junction type tuning circuit and a Josephson Flux-Flow oscillator as LO. The presented antenna utilizes truncation, perturbation, and slits to generate wideband circular polarization (CP) operation from its inherited linear polarization. International Journal of Antennas and Propagation is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles on the design, analysis, and applications of antennas, along with theoretical and practical studies relating the propagation of electromagnetic waves at all relevant frequencies, through. However, the size of these UWB diversity antennas. the stub by keeping the bow-tie slot dimensions same. dimensions of the cavity. This antenna which operates in the mentioned wideband frequency is highly acceptable for microwave imaging application. 6 GHz; Ring-Resonator Microstrip Antenna; Shorted C-Shaped Microstrip Antenna Stacked U-slot Antenna; Wideband Double U-slot Patch Antenna for 1 GHz to 2 GHz; Wideband RSMA with U-slot 0. The merits of printed antenna such as light weight, small size and low profile make them an attractive candidate for UWB antenna development [3].
