The main motive of the miniaturized sensing antennas is low profile, compact square antennas to operate in K and Ka band applications. Since Substrate integrated waveguide (SIW) technology exhibits low copper loss, reduced surface waves and low dielectric loss property it is involved in the design. In this paper, a square waveguide resonator is proposed to covers frequency range of 20 to 45 GHz and the electrical parameters of the antenna like return loss, gain, radiation pattern, and VSWR are investigated. The square resonator has conducting cylinders know as via-holes along the sides of the patch which makes it a good electrical conductor (EC) and from other side a good magnetic conductor (MC). The proposed square resonators contribute to the design of compact structure. The structure of HMSIW has Triple band which has maximum return loss of -20.5 dB at 36.75 GHz whereas FMSIW square shaped antenna has Hepta band maximum return loss of -21.5 dB at 40.5 GHz..
