Design of reconfigurable antennas based on an L-shaped slot ... A basic antenna structure to design pattern and pattern/frequency reconfigurable antennas is proposed. The structure consists of an L-shaped slot, PIN diodes, lumped capacitors and bias networks. The PIN diodes and the lumped capacitors located at specific positions are used to create short circuits across the slot.

so that there is no coupling between these two polarizations. The switching speed of the PIN diodes is slower than the MEMS-based switches. Nanbo Jin designed the patch antenna [2] with switchable slot (PASS).This concept is implemented to design a novel reconfigurable antenna with both frequency and polarization diversities.
Layer 2 is the multi-path propagation [6, 7]. Generally, a patch antenna, functional microstrip circuit module which includes a single-feed or dual-feed, can generate circular polarized feed-line, two branches of microstrip lines, two PIN … Hlavni dokument_zlatnicek V práci budou řešeny úpravy tvaru pahýlu pro zapojení PIN diod.
