Dielectric resonator antenna for Short Range Wireless Communication Applications

摘要: Present scenario of communication, all wired ones replacing with wireless. So, to achieve efficient communication in wireless technology, radiators required. One such is Dielectric resonator antenna. The extremely wide spectrum 3.1 10.6 GHz 15 bands bandwidth greater than 500 MHz and power limit less -41.3 dBm/MHz announced by FCC for Ultra band. release this Spectrum has rapidly increased the research UWB technology communications, radar imaging, localization applications. Radio systems based on offer opportunities transmission high data rate signals, coding security low probability intercept, especially multi user network applications .DRA one best antennas due its attractive features like radiation efficiency, dissipation loss, small size, light weight, profile. Moreover, DRAs which possess a degree design flexibility, have emerged as an ideal candidate band, cost-effective Second antenna designed resonates at 5.5 suitable 802.11a WLAN applications.Third resonate two different frequencies 2.42 other 9.13 GHz.
