This article presents the design of a novel planar antenna structure comprising two pairs of interconnected meandered line loops that are grounded to a truncated T-shaped ground plane through two via holes. The T-shaped ground plane is used as a reflector to enhance the performance of the antenna. The resulting antenna is compact occupying an area of 38.5x36.6mm(2) (0.070(o)x0.067(o)), where free-space wavelength is 550MHz. The antenna radiates omnidirectionally in the E plane across its operational bandwidth (550MHz to 3.85GHz) with peak gain and efficiency of 5.5dBi and 90.1%, respectively, at 2.35GHz and reflection coefficient better than -10dB. These characteristics make the antenna suitable for numerous applications, in particular, JCDMA, UHF RFID, GSM 900, GPS, KPCS, DCS, IMT-2000, WiMAX, WiFi, and Bluetooth.
