Microstrip Patch Antenna Array

Microstrip antennas are used in applications where size, weight, cost and ease of installation are required. These antennas are low-profile and conformable to both planar and non-planar surfaces. Antenna characteristics are also dependent of dielectric parameters.
Antenna arrays are used in order to achieve higher gain. Antenna arrays are more demanding for EM simulation than single element antennas due to their electrical size.
A model of a microstrip patch array is simulated in WIPL-D Pro. Analyzed microstrip array consists of 144 elements. The feeding lines are also modeled. This antennas intended application is in anti-collision radars... read more

Waveguide Slot Array Simulation

Slotted waveguide arrays consist of a number of slots cut into the walls of a waveguide forming an array with the slots acting as individual radiating elements.
The resonant slot array employs near half-wavelength long resonant slots as individual radiators. The array elements are excited in the standing wave mode, which is formed by a short circuit end of the waveguide.
The concrete design task here is a 10-element transversal slot array cut into the upper wide side of a WR-51 standard rectangular waveguide. The operating frequency is the center of the K band, 18.5 GHz. The dimensions of the waveguide cross-section are A=0.51 inch=12.95 mm, and B=0.255 inch=6.477 mm. ... read more
