This paper presents the design of a high efficiency corporate-fed 8×8-slot array antenna in the 60 GHz band. The antenna is built using three unconnected metal layers based on Artificial Magnetic Conductor (AMC) in gap waveguide technology. A 2×2 cavity-backed ...
Design of a Ku-Band Filter Based on Groove Gap Waveguide Gap waveguide technology is based on parallel-plate waveguide configuration and using a periodic array of electromagnetic bandgap structure to control the direction of propagation. In fact, this technology overcomes the problem of good electrical contact associated with 60GHz corrugated slot antenna array with ridge gap waveguide ...

Waveguide Slot Array Antennas | springerprofessional.de At first, the history on studies on waveguide slot antennas and arrays is described briefly.The procedure to design a waveguide slot array antenna is explained, and also the analysis model to design the element is discussed as well as the scattering matrix in connecting the equivalent circuit...
The problem arises because the physical dimensions along the E-plane is much shorter than that along the H-plane (the slotted waveguide is long but thin). In general, a longer antenna (or longer array) produces a narrower beam. This problem can be circumvented by arranging slotted waveguides in parallel, as shown in Figure 1. Figure 1.
Antenna Arrays. Recall from our previous discussion of the 2-element array that the total eld pattern from an array could be found by multiplying the element factor (the pattern produced by a single element) by the array factor.Periodic radiating slots cut in a waveguide are an example. Phased-Array Antenna - an overview | ScienceDirect… In particular, phased array technology allows the radar beam to be controlled and adapted almost instantaneously. This flexibility enables the radar to carryPhase shifters are widely employed in radar systems based on phased antenna arrays. MEMS technology offers much lower insertion loss...
