Fuzzy Controlled Wind Generation System


Fuzzy Controlled Wind Generation System

This chapter focuses on the design of a dual-band antenna intended for existing wireless services including LTE, GPS, GSM, PCS, DCS, GPS, UMTS, WLAN, and WiMAX bands. The present techniques available in the open literature include the modification of the main radiator via bending, folding, meandering, and wrapping. Each approach offers different advantages, depending on the required application. The introduction of a ground slot in a finite antenna ground plane can be further extended to include reconfigurable features. Thus, such antennas that are compact and have multiband capability can be promising candidates for many wireless applications. Now, this slotted multi-band planar system is proposed to intend on working frequency bands such as IN GPS, WLAN (over two frequency band spectrum), and WiMAX.Fuzzy Controlled Wind Generation System


 Antennas that are used before are capable of working in particular frequency applications. Where quarter wavelength radiators used are subjected to miniaturization which affects to form limited bandwidth and low radiation efficiency.


Less reception of due to high return loss due to a single patch antenna is used for each individual device.


 It is capable of working in 4 frequency bands and for 3 applications as built-in by one antenna. The miniaturization is done in various stubbed arms that two E-shaped stubs and a T-shaped stub designed optimistically to achieve minimal return loss over the four bands of the frequency spectrum.

Such as

  • 575-1.665GHz GPS
  • 4-2.545GHz IEEE 802.11b&g WLAN
  • 27-3.97GHz WiMAX
  • 17-5.93GHz IEEE 802.11a WLAN
