Planar microstrip YAGI antenna array [PDF]
, 1993 A directional microstrip antenna includes a driven patch surrounded by an isolated reflector and one or more coplanar directors, all separated from a ground plane on the order of 0.1 wavelength or less to provide end fire beam directivity without ...

Measurement techniques for cryogenic Ka-band microstrip antennas [PDF]
The measurement of cryogenic antennas poses unique logistical problems since the antenna under test must be embedded in a cooling chamber. A method of measuring the performance of cryogenic microstrip antennas using a closed cycle gas cooled refrigerator

In this work, a rectangular microstrip antenna with inset is designed, simulated and optimized. In the optimization process the patch is deformed, it new antenna present a amorphous patch. The optimization process was conducted with Genetic Algorithm (GA), S11 parameters was obtained with full wave Finite-Differences Time-Domain (FDTD-3D), and the ...
