Abstract

This paper presents an inverted C-shape microstrip patch antenna for L-band (1-2 GHz) application. The proposed antenna is suitable for dual band operation. The inverted C-shape microstrip patch is design for getting dual band. This antenna is suitable for GPS (global positioning system) carriers and satellite mobile phone application that is good for fast & highly accurate information transformation. We observe the simulated & validated result of proposed antenna by IE3D simulator and Agilent N9923A and to achieve a dual band. The bandwidth of lower band is 77MHz (freq. range 1.311-1.388GHz & C.F. is 1.377GHz) and upper band is 153MHz (freq. range 1.49-1.643GHz & C.F. is 1.579GHz) with -10dB return loss and 3.04 & 3.12dBi gain for lower and upper band. The maximum radiating efficiency of designed antenna is 99% and directivity is 4.6 dBi
