Design and development of printed antenna remote units for optically distributed mobile communications

Abstract

The first demonstration of a printed antenna remote unit (ARU) for optically distributed mobile communications compliant with the 1.9-GHz PCN specifications is presented. The ARU consists of a cavity-backed printed antenna with appropriate RF and photonic circuitry. The ARU is low cost, compact, robust, and can be easily positioned in typical microcell/picocell sites. A summary of the design procedure for the ARU and the measured results are given. The developed ARU is a key component for the successful deployment of future optically distributed microcellular mobile communications systems.

Compact GNSS Metasurface-Inspired Cavity Antennas

“…In [8], a stacked linearly-polarized (LP) configuration is introduced to enhance the antenna bandwidth by a factor 3.3, compared to a single-layer patch. Similarly the stacked-patch configuration proposed in [9] exhibits a -10-dB reflection bandwidth of 23%. The LP magneto-electric dipole antenna integrated into a lowprofile cavity described in [10] exhibits an impedance bandwidth of 54%.…”

A Wideband Circularly Polarized Patch Antenna for 60 GHz Wireless Communications

“…In this paper, we present the detailed design of a 60 GHz left-hand circular polarized antenna [27] that has a good overall performance by combining various techniques reported in [5][6][7][8][9][10][11][12][13][14][15][16][29][30][31]. This patch antenna incorporates a diagonal slot at the center and features a superstrate and an air cavity backing to achieve desired performances including wide bandwidth, high efficiency and low axial ratio.…”

“…As shown in [5], cavity backing can isolate an antenna from its surroundings, suppress surface waves and increase antenna bandwidth. The detailed characteristics of various cavity backed antennas are summarized in [6].…”
