N2 - A four-way unequal power divider is developed to feed a linear array proximity coupled microstrip antenna. The unequal power divider excitation coefficients follow the chebyshev polynomial. The simulation result shows that the four element proximity coupled microstrip antenna array with unequal power divider has achieved a sidelobe level suppression of 18.7 dB with backlobe level suppression of 16.5 dB. Furthermore the antenna gain of 8.81 dB was also achieved. Measurement results of the antenna with unequal power divider show similar result with the simulation. Measurement results show sidelobe level suppression of 18.1 dB with backlobe level suppression of 19.4 dB.
