TLDR
In this paper, a dual-polarized ultra wideband horn antenna with a coaxial line to quadruple-ridged waveguide transition and a new technique for tapering the flared section of the horn is introduced to improve the return loss and matching of the impedance, respectively.Abstract:
This paper describes a novel design of a dual-polarized ultra wideband horn antenna. Based on a VSWR ≤ 2.6, the bandwidth of the designed UWB horn antenna is from 8–18 GHz, most suitable for radar systems. A new coaxial line to quadruple-ridged waveguide transition and a new technique for tapering the flared section of the horn is introduced to improve the return loss and matching of the impedance, respectively. Results of simulation for VSWR, isolation, gain and radiation pattern of designed horn antenna are presented and discussed.read more

A Compact Ultra-Wideband Microstrip Antenna with Multiple Notches
TL;DR: In this paper, a new compact circular monopole ultra wideband antenna with multiple narrow bands notched is proposed, which is implemented by using the existing techniques, such as loading a L-type band-stop filter, inserting a split ring resonator (SRR), and the method we proposed that connecting L branches on the radiation disk.
