Miniaturized Planar Monopole UWB Antenna with Integrated RFID/GPS/GSM/WLAN Bands Using Capactively Loaded Loop Resonator (CLLRs)

By Mubarak Sani Ellis Ahmed Abdul-Rahman Jerry John Kponyo

A miniaturized multiband planar monopole Ultrawideband (UWB) antenna is presented. The penta-band antenna is comprised of a: 3.1 – 10.6 GHz UWB band, 2.4 WLAN band, 1.8 GHz GSM band, 1.3 GHz GPS and a 0.95 GHz RFID band. The proposed UWB band is realized by using half of a conventional rectangular radiator size while the other half is used to realize the other bands by employing quarter wavelength U and G shaped strips called folded CLLRs (capacitively loaded loop resonators). The designed penta-band antenna has an overall size of 25 x 30 mm2. The measured and simulated results of the fabricated prototype are compared and satisfactory results are achieved.
