A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern.
Reconfigurable Microstrip Patch – Slot Antenna Array The major wide frequency range in those two modes. advantage of reconfigurable antenna is that, such antennas are A frequency-reconfigurable micro-strip patch switchable to designed without causing an increase in the total area of the slot antenna is proposed in [7].

A polarization reconfigurable antenna is designed initially to function at 5.8GHz. A rectangular ring slot is cut thereafter in the original patch to function at lower resonance of 5.2GHz. Pin …
In this letter, we have designed a new printed slot-antenna with multiple reconfigurable bands and wide operating range. The structure is based on a square patch antenna with centered Koch-Island fractal slot and integrated switches (inside the slot) for frequency reconfigurable property. Compact Reconfigurable Antenna with an Omnidirectional ... In this study, a compact MPES reconfigurable antenna with an omnidirectional mode and four directional modes for DoA sensor applications in the C-band is proposed. This frequency band has been chosen for its specific low absorption propagative characteristics [52,53,54]. The operation frequencies are designed in a wide band because a wide band ...
