Abstrak

The paper presents a substrate-integrated waveguide array antenna with power divider structure. The antenna is composed of four mirrored inverted triangular slotted antennas, which allow the radiation pattern to converge. The SIW array antennas with this power divider structure have the same radiation field pattern, reflection coefficient, simulation results, and measurement results. The frequency band covers 28.4–29.8 GHz. The substrate is Rogers RT5880 with an antenna size of 36 × 46 mm. Considering the application of millimeter-wave antennas in wearable devices in the future, the evaluation of the electromagnetic energy absorption ratio complies with the specifications formulated by the Federal Communications Commission. The 11.6-dBi peak main beam gain and good directivity of the radiating field pattern make this antenna very competitive for applications in the n257 and partial coverage of the upper n261 band 1.
