A radar module (100; 200) comprises a low temperature co-fired ceramic, LTCC, substrate (101; 201), with a radar chip (102; 202) attached to a first surface (101a; 201a) of the LTCC substrate (101; 201) and a transmitting antenna (105, 106) for transmitting the radar signal attached to a second surface (101b; 201b) of the LTCC substrate (101; 201). The radar chip (102; 202) is configured to generate a radar signal for transmission. The transmitting antenna (105, 106) is configured to communicate with the radar chip (102; 202) through the LTCC substrate (101; 201). The radar module (100; 200) further comprises a beam steering element (205) configured to introduce a phase delay to the radar signal in order to adjust a first component of a direction of transmission of the radar signal.
