A simple and effective broadband decoupling structure for UWB-MIMO antenna
A new type of closed square ring decoupling structure is proposed in this letter, which can effectively reduce the coupling of antennas. The designed antenna is composed of two elliptical monopoles and a common ground loaded with a broadband parasitic decoupling structure. Considering the impedance matching, each antenna element is changed from the original rectangular microstrip feed to a tapered
Design and development of optically transparent rectenna for RF energy harvesting applications
An optically transparent ultra-wideband (UWB) Vivaldi antenna with a rectifier circuit is proposed in this paper. The proposed antenna is designed and fabricated on a soda-lime glass substrate with fluorine doped conductive oxide (FTO) as the conductive layer. A radial stub is used for better impedance matching and enhancing the impedance bandwidth of the antenna. It operates over a frequency rang
Robustness study of bandpass NGD behavior of ring-stub microstrip circuit under temperature variation
This paper explores an original study of bandpass (BP) negative group delay (NGD) robustness applied to the ring-stub passive circuit. The proof of concept (PoC) circuit is constituted by a ring associated with the open-end stub implemented in microstrip technology. An innovative experimental setup of a temperature room containing the NGD PoC connected to a vector network analyzer is described. Th
Untilted edge slot antennas excited by T-shaped wires
An effective method is proposed to excite the untilted edge slot antennas. In the proposed method, two T-shaped wires are placed at both sides of each untilted slot. Two legs of each T-shaped wire are connected to the waveguide walls, while the third leg is open. One of the T-shaped wires connects the upper broad wall of the waveguide to the narrow wall of the waveguide which contains the slots. S
Dual-band-notched UWB MIMO antennas with miniaturization using half-cutting technology
A compact four-element ultra-wideband (UWB) multiple-input?multiple-output (MIMO) antenna with dual polarization and dual-notched capabilities was developed and fabricated. The MIMO antenna is composed of four orthogonally placed half-cutting UWB antenna elements. This orthogonal placement improves the isolation. Furthermore, an L-shaped slot and a continuous bending slot are etched to realize the
