In this work, a novel topology of groove gap
waveguide (GGW) technology is presented to facilitate the
fabrication process by Computer Numerical Control (CNC)
milling. GGW has been proposed as an interesting alternative to
the rectangular waveguide for the design of microwave and
millimeter-wave components. This technology consists of two
parallel metal plates, where one of them has a (lambda)/4-height pin bed
that provides a high impedance condition at the plane over the
pins, avoiding electrical contact requirement with the upper plate
and hence facilitating the fabrication requirements. However, the
manufacture by CNC milling of the pins may be troublesome,
especially for devices operating at high frequency. A way to
facilitate this process is achieved by using pins with reduced
height. Moreover, the proposed configuration allows us to
maintain the standard dimension ports of the equivalent
rectangular waveguide and the operation in its corresponding
bandwidth. A comparison with other GGW topologies has been
presented and a bandpass filter has been fabricated to validate
its usefulness. [--]
