Abstract

A novel slot line fed ultra compact antenna with a wide bandwidth, operating in 900MHz range is developed and discussed. Antenna offers a frequency band of operation ranging from 792 MHz to 1.05 GHz with a percentage bandwidth of 28% which is much more than FCC specified bandwidth limit for wide band antennas. Overall size of the antenna is of the order of 0.059?g × 0.059?g × 0.007?g which is very compact and this compactness obtained without any lumped RLC elements. Developed antenna structure is characterized by directional radiation pattern, good gain and moderate radiation efficiency. FDTD model and equivalent RLC model of the antenna is also developed and analyzed.
