초록

In this paper, A small inverted F Antenna with 1.9 GHz frequency band is studied theoretically, characterized by numerical analysis with computer and fabricated in order to use in the proximity sensor. Because of small space for antenna in proximity sensor, .lambda. /4 length plate and dielectric material are used to reduce the size of antenna and broaden the bandwidth. Finite ground body's affection is compensated by dielectric top loading effect which strengthen front direction power about 4 dB. Fabricated antenna is measured and the result is that resonant frequency is 1900.05 MHz, VSWR is 1.02, bandwidth is 194 MHz and input impedance is 50.45-j0.108 [ .ohm. ].
