Low density polyethylene (LDPE)/Alumina (Al₂O₃) composite systems have been studied as an alternate substrate for microstrip patch antennas (MPA). Morphological, thermal and microwave characterizations of the composites are carried out for different volume fractions of Al₂O₃ in the LDPE matrix. The size and the distribution of alumina particles are quite uniform in the composite. Enhancement of thermal and microwave properties of the composite over the parent polymer is observed. Simple rectangular MPA in X-band is fabricated on the composite material to verify its applicability as substrates for MPA. A return loss of ~ -26dB is observed at the design frequency.
