Rectangular slot cut circular microstrip antennas
Multi band dual polarized circular microstrip antenna cut with circular and rectangular slot is proposed. The circular slot in circular patch degenerates patch TM11 and TM21 modes into two orthogonal modes to realize multi band characteristics. The rectangular slot helps in optimizing the input impedance at degenerated resonant modes to realize optimum bandwidth of 1 to 2% in 1000 MHz frequency range. The proposed dual polarized configuration shows radiation in the broadside direction for all the resonant mode frequencies.
