A Novel Dual-Band, Dual-Polarized, Miniaturized and Low-Profile Base Station Antenna


During this paper, a novel twin-band, dual-polarized, miniaturized and low-profile base station antenna operating within the frequency bands of 820–960 and 1710–2170 MHz is designed. Elements are organized such that high-frequency components are embedded in low frequency components to scale back volume. A baffle is employed to replicate the transmitted power density within the forward direction and additionally improve isolation between elements. So, surrounding isolation baffles and rectangular baffles are appended around high-frequency parts and low-frequency components, respectively. The diameter of the proposed antenna cowl is only two hundred mm, which is smaller than the prevailing antenna diameter of 280 mm. Compared with the other commonly used antennas, the proposed antenna additionally has some advantages like concealment and low profile using a tubular type of radome, that can easily integrate the proposed antenna with the encircling surroundings. The measured results verify that the proposed antenna meets the stringent style requirements: voltage standing wave ratio (VSWR) is but 1.three, the isolation is bigger than thirty dB, and the pattern parameters additionally meet telecommunications trade standards.
