This paper presents an evaluation of a prototype slotted waveguide array antenna suitable for a dual-polarized lowside-lobe array antenna manufactured by injection-molding. The resin waveguide is divided into two components, and then both are fastened using screws and bosses. The waveguides are needed to be arranged closely in order to apply them to a phased array antenna. This requires the bosses to be pushed into the waveguide, which deteriorates radiation pattern. We have proposed a resin waveguide with irises near the bosses to cancel the effects of the boss, and designed resin-injection-molded slotted waveguide array antenna. We manufactured a prototype of the proposed antenna. Measured bandwidth, side lobe level, and cross polarization of the vertically polarized antenna are 3.0%, -31.5 dB, and -42.7 dB, respectively. We confirmed the effectiveness of the proposed structure. |
