摘要

A compact dual mode wideband antenna is presented in this paper whichoperates from 24.8 to 31.6 GHz (suitable for 5G applications). The antenna isbased on substrate integrated waveguide (SIW) and consists of a two-elementarray of half-bow-tie slots. Each slot excites two modes (slot mode and halfpatch mode) in the antenna due to its geometry. The resonant frequencies inthese modes are optimized to achieve wide impedance bandwidth using AnsysHFSS. A prototype is fabricated and its measured impedance bandwidth is6.8 GHz, which is in close agreement with the simulated one. It also has a peakgain of 8.5 dBi at 30.4 GHz and its physical size is 2.4λ_g × λ_g, where λ_g is theguide wavelength at center frequency.
