Particularly, the slotted waveguide antenna arrays (SWAAs) present an excellent compromise among cost, complexity, and performance in terms of coverage.
The current work relies on the development of two mm-wave waveguide-based antenna arrays for 5G networks: a high-gain omnidirectional antenna array and a dual-band slotted waveguide antenna array.
One type of antennas used for radar and satellite communications in the aerospace and aviation industry is the Slotted Waveguide Antenna (SWA).
One form of CLAS, known as Slotted Waveguide Antenna Stiffened Structure (SWASS), integrates Slotted Waveguide Antennas (SWAs) into the load-bearing vehicle structure (see Figure 1).
One potential implementation of CLAS for Ground Moving Target Indicator (GMTI)/Synthetic Aperture Radar (SAR) radar is Slotted Waveguide Antenna Stiffened Structure (SWASS) .
This design is required to prevent higher order modes [31, 32] when the loop feed is inserted in a standing wave slotted waveguide antenna. A Wiltron 360B vector network analyzer was used to measure the reflection ([absolute value of [s.sub.11]]) and transmission ([absolute value of [s.sub.21]]) coefficients.
Coverage includes instructions for getting Google Maps on a mobile phone, building a slotted waveguide antenna
, and stopping "moochers" from stealing Wi- Fi bandwidth.
His major research interests are waveguide and slotted waveguide antenna
systems for communication and radar applications.
Slotted waveguide antenna
array is a good candidate in the areas of radar and communication systems due to its attractive features, such as low power loss, low cross-polarization levels, low profile, high power capacity, high efficiency, and accurate control of amplitude and phase distributions.
 designed and characterized a slotted waveguide antenna
to be used as the feeder of a transmitarray of an X-band navigation radar, which is 10 cm wide and 153 cm long.

The aim of the activity will consist in investigating advanced concepts of slotted waveguide antennas
enabling dual polarisation operation while remaining low lossand easy to manufacture.
