  3. Abstract Wireless communication systems have progressed very fast in last decade and became most important part in notebooks and cellar phone because of low cast device and mobility and for faster communication and transfer more data designed broadband system and for UWB application we need antenna with more bandwidth . This paper presents a triple band Microstrip slot antenna with SRR shape ring. The prototype antenna is designed and simulated for wireless communication like IEEE 802.11(g/b/a), WIMAX and GPRS application. The bandwidths are around 5.1% for 1.93GHz (1880-1980), 35.4 % for 2.75 GHz (2400-3100 MHz) and 28% for 5.7GHz (4900-6500MHz).

  8. Wireless Spectrum

  9. The UWB system usually applied for WLAN (5.15-5.825GHz) for IEEE 802.11.a and WiMAX (5.25-5.85GHz) system. Digital Cellular System DCS (1.71-1.88GHz), PCS (1.75-1.87GHz), UMTS (1.92-2.17GHz) and 2.4GHz WLAN are some frequencies that are used for wireless and personal communication and these frequencies are lower than UWB systems. It should be mentioned that 3.3-3.8 GHz use for WiMAX application and IMT advanced system or fourth generation (4G) mobile communication system in the range of 3.4-4.2 GHz. IEEE 802.11a standard is considered 5.15-5.35 GHz and 5.725-5.825 GHz as send band and receive band respectively, IEEE 802.11bg applied 2.4GHz (2.4– 2.484 GHz) for WLAN application

  19. Conclusion This paper is presented triple-band Microstrip slot antenna with SRR shape ring with bandwidths are around 5.1% for 1.93 GHz (1880-1980), 35.4 % for 2.75 GHz (2400-3100 MHz) and 28% for 5. 7 GHz (4900-6500MHz). It has enough gain and sufficient performance for wireless communication and here shows that ring and SRR parasitic elements are useful for antenna miniaturization and multi band design structure .The paper also shows the effect of parasitic elements on antenna gain and current distribution . As shows in this article the current is increased in SRR model but gain reduce a little in comparison to ring model .It may be occurred because of SRR element distance and placement for future research we can notice this parameter for increase antenna gain . With SRR and rings implementation antenna gain is increased more 2 dBi at 5.2 GHz.
