LHCP four patches stack triangular truncated antenna using corporate feed microstrip-line for CP-SAR sensor

<span>In this paper, we acquire the configuration of left-hand circular polarization (LHCP) array four patches stack triangular truncated microstrip antenna. This construction use basic corporate feed microstrip-line with modified lossless T-junction power divider on radiating patch for circularly polarized-synthetic aperture radar (CP-SAR) sensor embedded unmanned aerial vehicle (UAV) compact, small, and simple configuration. The design (CP) is realized by truncating whole three tips adjusting parameters antenna at target frequency, <em>f </em>= 5.2 GHz. results characteristic performance <em>S</em>-parameter LHCP frequency show successively about 9.74 dBic gain, 2.89 dB axial ratio (<em>Ar</em>), </span><span>-</span><span>10.91 S-parameter. Moreover, impedance bandwidth 3 dB-<em>Ar</em> are around 410 MHz (7.89%) 100 (1.92%), respectively.</span>
