Analysis of dual-polarized aperture-coupled microstrip antennas with h-shaped slots and equivalent circuit measurement stage of the antenna. A microstrip is a type of electrical transmission line used to transmit rf signals and are commonly fabricated using printed circuit board (pcb) technology compared to waveguides, microstrip is generally has a lower power handling capacity, and higher losses due to the fact that it is not enclosed.
The microstrip antennas were introduced only in the seventies, some twenty years after the introduction of the microstrip line, and became a very popular type of antenna, due to their low proﬁle, small. Literature has focused on the efficient analysis of the singly curved conformal microstrip antenna (sc-cma), with most published results for single linear polarization and microstrip antennas that conform to cylinders with electrically large radii (ie, kb 1, where is the free space k.
