A Frequency Reconfigurable Rotatable Antenna Design for ... front end design is the design of reconfigurable antenna. A reconfigurable antenna is essential to sense the entire spectrum of interest and to minimize interference and multipath problems within several frequency bands. Some of the recent works have been implemented using PIN diodes, RF-MEMS or laser diodes [3-5]. Slot antenna - Wikipedia 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.

Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. Frequency Reconfigurable Antenna – IJERT Frequency reconfigurable patch antennas have attracted significant attention due to their ability to cover multiple frequency bands [17-23]. A lot of work has been carried out frequency reconfigurable micro strip patch antenna for mobile communication standards summarized in [20]. Reconfigurable Microstrip Patch Antenna using ... - IOSR Journals reconfigurable circuitry that operates on each of these different frequencies. A Reconfigurable microstrip patch antenna is an antenna which can expand the system capability by adjusting its resonant frequency, radiation pattern and polarization. Reconfigurable antennas are becoming more important in defense and commercial

A wideband slot antenna with frequency- and pattern-reconfigurable characteristics for TD-LTE (3.4–3.8 GHz) and C-band (3.7–4.2 GHz) applications is proposed. The antenna consists of two symmetric slots that are fed by a fork-shaped microstrip line. Two PIN
