摘要：
A compact bi-directional leaky-wave antenna (LWA) based on TE20 mode substrate integrated waveguide (SIW) is proposed at X-band. The microstrip power divider-slotline transitions are utilised to excite TE20 mode SIW array in order to enhance the overall radiation capability of the designed structure. The rectangular slots are etched out on the top and bottom plane of SIW such a way that the orientation of the slots can perturb the distribution of electric field at TE20 mode and provide bi-directional radiation. The proposed antenna is working within the frequency range of 9.6-11.2 GHz (S-11 < -10 dB) having the beam scanning range of 66 degrees from both top and bottom side of the structure with maximum gain of 14 dBi. All experimental results show a fair agreement with the simulated data.
