In this paper, a design of broadband compact microstrip meshed patch antenna integrated with solar cells for Ku-band satellite applications is presented. A Plexiglas transparent substrate is also employed to enable the light to pass through with high efficiency to illuminate the solar panel cells while the RF performance is maintained with minimal degradation. This meshed patch antenna for two-way...
The concept of hybrid free space optical/radio frequency (FSO/RF) communications has been considered for the last mile access network applications. The existing schemes mostly use two separate transceiver antennas for outdoor terrestrial links of few kilometres long. In this paper, we propose and investigate a single hybrid FSO/RF antenna that could be used in high-speed access networks. We outline...
A compact InP modulator chip is presented for 32Gbaud coherent transmission having high efficiency and linear EO response V2π<5V and ER>25dB; and a full set of integrated waveguide detectors and phase-controls for testing, set-up and monitoring.
A low-profile, wideband transition between a coaxial waveguide and a substrate integrated waveguide (SIW) is presented in this paper. The transition is designed for a reconfigurable metamaterial antenna realized in multilayer Printed Circuit Board at X-band. The transition achieves S11 below −15dB across a bandwidth of 19%, making it attractive for many practical applications. Full wave simulation...
This paper presents a report on experimental set up and results for a hybrid free space optics (FSO)/radio frequency (RF) dual purpose antenna for outdoor applications. The basic design of the antenna is discussed and we present two sets of early experimental results for the signal to noise ratio (SNR) and the Q-factor for the RF and FSO simplex link at the far-field distance of RF antenna, respectively...
