Parallel Fed 2x1 Antenna Array Utilizing Surface Wave Cancellation on LTCC Substrate

Abstract : In this paper a novel design of an UE (User Equipment) antenna for the 60-GHz band is presented. The antenna was realized on LTCC A6M-E substrate to ease a later integration with the RF-chipset on a single module. To satisfy the requirement of a relative bandwidth of 15% an electrically thick substrate was utilized, which unfortunately leads to an undesired excitation of surface waves. A suppression of these dielectric modes was achieved by employing a cancellation technique of excited surface waves. The proposed antenna consists of two parallel fed aperture coupled microstrip patch antennas. The S-parameter and radiation pattern results (simulation and measurement) are presented and are used to verify the antenna design. The manufactured antenna exhibits a -10 dB impedance bandwidth of more than 9 GHz, a Half Power Beam Width (HPBW) greater than 60 degrees and a realized gain of more than 5.5 dBi over the bandwidth.
