This paper presents a balanced-fed aperturecoupled patch antenna suitable for broadband millimeter-wave communications. The antenna is realized in a low-cost PCB technology and can be integrated with RFIC chips. To improve antenna bandwidth and radiation efficiency, an air cavity has been embedded in the PCB stack. The measured antenna performances agree very well with the simulated results. The antenna has about 7 dBi gain, with at least 12 GHz impedance bandwidth.
