In examples, systems and methods for waveguide antenna arrays with integrated filters are described. An example waveguide antenna array element a waveguide section has a first end and second end. The waveguide section is configured to propagate electromagnetic energy. The waveguide antenna array element also includes a feed configured to launch an electromagnetic wave into the first end of the waveguide section. The waveguide antenna array element also includes a waveguide filter having at least one waveguide cavity coupled to the second end of the waveguide section. The waveguide filter is configured to pass a first set of electromagnetic frequencies and reject a second set of electromagnetic frequencies. Yet further, the waveguide antenna array element includes an antenna coupled to the waveguide filter configured to radiate a portion of the electromagnetic energy passed by the waveguide filter.
