Design and research of dielectric embedded microstripantenna with cylindrical conformal

Dielectric embedded antenna can solve the problem that the traditional antenna is oxidized with exposure in the air. At the same time, the concealment of the antenna is enhanced, especially the bandwidth of the antenna is widened. Conformal antennas can provide the desired antenna performance, and have no effect on the maneuverability of the carrier itself. In this paper, a microstrip dielectric embedded antenna with cylindrical conformal is proposed. The antenna is designed and simulated using the electromagnetic simulation software CST. The results show that the working bandwidth of the antenna is 440 MHz with reflection coefficient less than -10 dB increased by 29.4% compared with that of the unburied antenna with bandwidth of 340 MHz. The maximum gain in the operating band reaches 8.0 dB, which is 0.5 dB lower than the maximum gain of 8.5 dB of the general antenna, but the gain of the dielectric embedded antenna reaches the actual requirement of the antenna and the gain reduction is small. Microstrip dielectric embedded antenna with cylindrical conformal in the antenna pattern, standing wave ratio, impedance matching and other properties to meet the actual conditions, and have wider half-power beam width.
