摘要：
In this paper, an equilateral triangular HMSIW antenna excited with coaxial feed is chosen at 5.28 GHz representing TE101 mode with next higher TE202 mode operating at 9.57 GHz frequency in the X-band. Two sides of the antenna with fitted with metallic vias while the third side remains barren. The antenna is found to exhibit gain of 5.7 dBi and 7.5 dBi for the TE101 and TE202 mode respectively. A rectangular box-shaped dielectric resonator (DR) is now placed over the radiating wall. The antenna-DR composite structure resonating at the higher TE202 mode at 9.5 GHz and depicting an enhanced gain of 12 dBi is presented here for X-band microwave imaging and radar applications. All antennas are made-up with Arlon AD270 substrate and simulation results show a close resemblance when compared with measured ones.
