Series-Fed Arrays

Series-fed patch arrays with in-line feeding are very popular choice for 24 GHz and 77 GHz radars. These arrays provide least possible feeding network length, because patches are placed directly on feeding line.

Shunt-Fed Arrays

Series-fed patch arrays with shunt feeding of patches have larger feeding networks compared to in-line fed arrays. Patches are placed along feeding network with multiple power dividers.

Parallel-Fed Arrays

Parallel-fed patch arrays are pretty popular choice for applications such as simple narrow-beam radars and Wi-Fi antennas. Parallel-fed array main advantages are strict broadside radiation and wider achievable frequency bandwidth compared to series-fed arrays.

Element Weighting

In this lesson, we will learn how to implement antenna arrays with unequal power distribution. We also demonstrate how weighting coefficients W_i affect side lobe levels and beamwidth of antenna array.

Metamaterial Antenna

Mushroom-Type Electromagnetic Band Gap (EBG) Metamaterial antenna element for series-fed arrays consists of N rectangular patches with vias to ground in patch centers. Amount of power radiated by each element can be tuned by changing number of patches N and gap between adjacent patches.

Slotted Waveguide

Slotted waveguide array antenna can be implemented using cost-effective substrate integrate waveguide (SIW) technology. SIW waveguide side-walls are implemented using via fences. Diameter D_via and pitch P_via of side-wall vias are chosen to achieve low leakage and manufacturability.

Beamforming

Beamforming principle is based on applying progressive phase shifts to the signals transmitted (or received) by antenna elements or sub-arrays.
