“…For this frequency total substrate thickness (h + h a ) of 1.46 cm (∼0.1 g ), is selected. Using Equations (7) and (8), side length of ETMSA is calculated for f TM10 = 2000 MHz. Equation 7is obtained by substituting "m" = 1, "n" = 0 and "l" = 0, in the resonance frequency equation of ETMSA.…”

“…It is realized either by using offset position of the coaxial feed or by embedding narrow slots along the patch side length, at its vertex point and inside the patch, or by placing the open circuit stub on the patch edge or by employing Koch fractal geometry or by feeding the antenna using dual proximity strip. [5][6][7][8][9][10][11][12][13][14][15] Many of these designs offer narrow band CP response with axial ratio (AR) bandwidth (BW) in the range of 1%-1.7%. [5][6][7][8][9][10][11][12][13][14][15] Also the effects of slot or stub on the patch resonant modes and resonant length formulations at them is not presented.…”

The modified designs of different isosceles triangular microstrip antennas realized by overlapping two isosceles patches, are proposed for circularly polarized response. An offset distance between the two overlapped patches yield optimum spacing in between the orthogonal modes of the composite patch, to give circular polarization. Proposed configuration is investigated for angle increasing from 50 • to 100 •. An optimum response in terms of the bandwidth (BW) is obtained in 50 • modified isosceles patch. Here, input impedance and axial ratio (AR) BW of 646 MHz (52%) and 76 MHz (6.12%), respectively, is obtained. As an additional design feature, proposed configuration shows variation in the center frequency of AR BW against increasing isosceles angle and the offset distance. Proposed designs exhibit broadside radiation pattern with a gain of above 8 dBi, with a good agreement between the simulated and measured results. A new simpler design for circular polarized response supported with detailed design methodology are the new technical contributions in the proposed work.
