The far-field radiation characteristics of the proposed antenna were also investigated. As can be seen in Figure 5, the measured results show that the radiation patterns (co-polar and cross-polar patterns) at 1.9 GHz, 2.1 GHz, and 2.3 GHz operating frequencies show an approximately similar general p
## Abstract This article presents a compact branchβline coupler (BLC) for balancedβtype circuit application. It was designed by utilizing cascading multisection and capacitanceβloading technique for bandwidth increase and size reduction individually. The proposed BLC was simulated and fabricated. I
## Abstract This article presents the configuration and design method of a compact ultra wideband 3dB quadrature coupler employing a microstrip/slot technology. The proposed device uses two substrates with a common ground plane. It is formed by two identical multisection elliptical conducting strip
