A novel design of ultra-wideband star shaped printed monopole antenna is proposed. A star shaped structure is realized by combining triangular shaped planar monopole patch with its inverted configuration. A detailed parametric study of the offset placement of two triangular shaped patches with respect to the patch centroids, variation in distance between the base of composite structure and the ground...
In circularly polarized radiation, the rotational orientations of the transmitter and the receiver antennas are unimportant in relation to the received signal strength. In this paper, a center square slot cut elliptical patch microstrip antenna to realize a tunable circular polarization in 1000 MHz frequency band is proposed. It yields axial ratio bandwidth of nearly 1.2% over tunable range. A rectangular...
A novel compact ultra-wideband circular ring sector printed monopole antenna with decreasing Sectoral angle and modified feeding structure is proposed. A detailed parametric study for Sectoral angle decreasing from equivalent circular monopole patch to 330° ring Sector up till 60° ring Sectoral patch is presented. With decreasing angle ultra-wide band response with increasing lower frequency of the...
Analysis and design of multi-band dual polarized circular microstrip antenna with an angular cut and pair of rectangular slot in 1000 MHz frequency range is proposed. The angular cut degenerates TMjj and TM21 resonant modes of equivalent circular patch into two orthogonal modes to yield multi-band response. Further pair of rectangular slots optimizes the input impedance at degenerated resonant modes...
This paper proposes a novel Multi-band dual polarized elliptical shaped microstrip antenna cut with square and rectangular slot. The square slot in elliptical patch degenerates patch TM11 and TM21 modes into two orthogonal modes to realize multi-band characteristics. The optimization of the input impedance at degenerated resonant modes is done by the introduction of the rectangular slot to realize...
Circular polarized microstrip antennas are required in applications wherein an uncertainty in the direction of received signal polarization exist. In this paper an offset slot cut circular microstrip antenna to realize circular polarization in 1000 MHz frequency band is proposed. It yields axial ratio bandwidth of 10 MHz (∼1.2%). To increase the axial ratio bandwidth its gap-coupled array configuration...
