A flat Luneburg lens antenna is designed, fabricated and tested in the 60 GHz frequency band. The lens is built using an additive manufacturing technique and is excited by a conventional WR-15 rectangular waveguide. The radiation characteristics (mai

In this paper, a new family of ceramic resonators and filters is introduced. The proposed resonators are enabled by the integration of distributed resonators into standard Printed Circuit Board (PCB) substrates. This integration caters for not only a

In this paper, a novel low-cost method for coupling into Radio Frequency (RF) cavity filters is presented. The method is based on a non-galvanic and connector-free connection from the output of the power amplifier (PA) to the first resonator of the f

Modern wireless communication networks, particularly cellular networks utilize multiple antennas to improve the capacity and signal coverage. In these systems, typically an active transceiver is connected to each antenna. However, this one-to-one map

In this paper we present a highly compact and low-cost antenna solution based on a dielectric lens and a waveguide horn array feed for operation in the 57–64 GHz frequency band. The antenna is targeted for applications in point-to-point backhaul sy

In this paper we demonstrate the use of low-loss dielectric powders in the design and fabrication of RF filters. Initially, several different powders are tested for their RF performance — in particular their relative dielectric permittivity and los
