A novel dual‐band directional antenna with comb radiators using substrate integrated suspended line (SISL) technology is proposed for wireless local area network (WLAN) applications. The proposed SISL antenna is designed to be self‐packaged using five substrate layers with embedded air cavities. H‐shape strip and rectangle slot are used to achieve the band from 2.43 to 2.54 GHz with gain of 2.2 dBi. Via is utilised to connect the antenna patch with feeding line, then the second band from 5.33 to 6.22 GHz with gain of 10.1 dBi is obtained. Additionally, the cross‐polarisation levels less than −15 dB and front‐to‐back ratio larger than 15 dB are achieved.
