Abstract (en)
[origin: WO9532528A1] A modular microstrip antenna system has a first antenna portion (101), a second antenna portion (120) and a connector (124) for removably connecting the first (101) and second (120) antenna portions. In the first antenna portion (101), a radiating element (106) is mounted on a grounded dielectric substrate (108). The ground plane (110) has an opening (112) therethrough, the opening (112) aligned with the radiating element (106). The second antenna portion (120) has a conductive substrate on a dielectric substrate, the conductive substrate having an aperture (122) therethrough. On the other side of the dielectric substrate is a microstrip transmission line (126). The aperture (122) is aligned between the radiating element (106) and the transmission line (126), and sized to electromagnetically couple the radiating element (106) to the transmission line (126). The opening (112) in the ground plane (110) is sized to accommodate the aperture (122) to allow for the electromagnetic coupling.
