A compact dual mode wideband antenna is presented in this paper which operates from 24.8 to 31.6 GHz (suitable for 5G applications). The antenna is based on substrate integrated waveguide (SIW) and consists of a two‐element array of half‐bow‐tie slots. Each slot excites two modes (slot mode and half patch mode) in the antenna due to its geometry. The resonant frequencies in these modes are optimized to achieve wide impedance bandwidth using Ansys HFSS. A prototype is fabricated and its measured impedance bandwidth is 6.8 GHz, which is in close agreement with the simulated one. It also has a peak gain of 8.5 dBi at 30.4 GHz and its physical size is 2.4 λ g  ×  λ g , where λ g is the guide wavelength at center frequency.
