This paper present an investigation on integration square loop antenna with the Surface Mount Device (SMD) Light Emitting Diode (LED). The parameters of the antenna will be determined by using basic square antenna equations. The antenna is designed by using CST Microwave Studio 2013 and fabricated on the FR-4 substrate. The data for experimental is taken by using Vector Network Analyzer (VNA) to get the return loss value and the radiation pattern is captured in a chamber room. The performances of the integrated antenna were investigated in term of the return loss, resonant frequency, gain, radiation pattern and VSWR. Both result from simulation and measurement arc compared and analysed. The integrated LED also affected the performance of the antenna by shifting the frequency to the lower frequency and the return loss also change to deeper value. It is verified that LED is acts like a bridge on the antenna and it has the inductance characteristic.
