Annular Slot Antenna - How is Annular Slot Antenna ... In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2. Design of a compact UWB antenna for mimo applications by ...

CPW Fed Monopole Antenna for Future UWB Diversity…
Design and Analysis of a CPW-Fed Broadband Conical Conformal ... A CPW-fed microstrip monopole antenna which is conformal to a conical surface is presented in this paper. It has a simple structure printed on a substrate with dielectric constant of 2.55 and thickness of 0.2mm. IET Digital Library: Uniplanar polarisation diversity antenna ... A new compact, uniplanar, polarisation-diversity, monopole-like slot antenna for ultra-wideband (UWB) systems is presented. The proposed design effectively integrates orthogonally fed slot antennas, utilising the uniplanar nature of coplanar waveguide without degrading the time-domain characteristics and diversity performance.
