Abstract

The more frequently used technique to realize broadband and dual band microstrip antenna is by cutting the slot at an appropriate position inside the patch. In this paper, an in-depth analysis of dual band rectangular slot cut rectangular microstrip antenna and plus shaped slot cut broadband rectangular microstrip antenna is presented. The dual band slot cut antenna is reported to be resonant at 3640 and 4080 MHz. Through the analysis it was observed that the slot modifies the resonance frequencies of TM11 and TM02 mode of the rectangular patch and optimizes the impedance at them to realize dual frequency response. Further when an additional horizontal slot is cut inside the above rectangular slot which realizes plus shaped slot, it further reduces TM02 mode resonance frequency and along with the TM11 patch mode, yields broadband response. The proposed analysis gives an insight into the functioning of the slot cut patch antennas operating at higher order modes as well as it will help them in designing them in given frequency band.
