“…It has been successfully used to package antennas for transceivers at mm-wave frequencies [9,10]. However, because of its relatively high dielectric constant, this one often requires additional processing to improve radiation performance [11,12]. Also, if integrating a full system, LTCC's lamination temperature of 800°C would damage the IC's in an embedded scheme.…”

This study presents a study of different antenna orientations to minimise coupling effects in the radiation patterns of two dipole arrays packaged together on multilayer organic (MLO) substrates. These effects are evident in the various ripples found in the pattern cuts of the arrays. The substrates used in the stack-up are Rogers' RO3003™ and ULTRALAM3850 ® . The two arrays, at 57 and 80 GHz, are fed together through a T-junction. The orientations studied consist of 0°, 45°and 90°. E-and H-plane patterns were measured for all orientations. Significant interference was seen in the E-plane for the 0°o rientation and H-plane for the 90°orientation. This was reduced in the 45°orientation, which yielded smoother patterns than its respective counterparts in 0°and 90°orientations. Adding 5 mm of extra distance in the configurations reduced either the amount of ripples (by 0.75 for 57 GHz and 1.75 for 80 GHz) or their average level (by 0.3 dBi for 57 GHz and 0.785 dBi for 80 GHz). The gain attained for the designs was >9 dBi and agreed well with simulated results. Guidelines for packaged antenna integration for mm-wave high speed communications based on the experiments are provided.

“…They are generally designed based on integrated circuits (ICs) [15][16][17], low-temperature cofired ceramic (LTCC) [18], micro-machined [7,19,20] or commonly used substrate technologies [5,8,11,14,[21][22][23]. The former two types infuse innovations into the mm-wave antenna technologies, but the latter are still the most popular ways so far for the majority of manufacturers and users due to their low investments on research and development.…”

Abstract-Although many directive antennas operating in a narrow band of millimeter (mm) waves were reported, e.g., antennas for 60-GHz wireless local area network (WLAN), their wideband counterparts are still unpopular. Cavity-backed antennas (CBAs) are widely developed and reported in microwave frequency bands, but handful of literatures can be found about mm-wave CBAs in spite that their many properties are quite suitable for mm-wave applications. This paper presents a wideband unidirectional CBA with a bowtie exciter, operating in a frequency band of 40 ∼ over 75 GHz, and it is carefully analyzed in terms of influences of all components on the radiation patterns, broadside gains, and reflection coefficients of the proposed antenna. Then, the antenna prototype is built by generic printed circuit board (PCB) technologies, and measurements prove the validity of simulations.

“…When measuring PAA, especially for 2-D element antenna allocation array antenna [2], 3-D radiation pattern measurement is preferred. For a 2-D measurement, we need only a turn table to rotate an antenna under test (the AUT).…”

Using 60-GHz band, multi-GHz bandwidth can be achieved for wireless personal area network (WPAN). However, WPAN requires high gain wide coverage area phased array antenna (PAA) for practical uses. In measurement of PAA, 3-D radiation pattern measurement is preferred. However, 2-D measurement is usually used because of limitations of measurement system. In this work, we propose a measurement method that can reduce measurement time for PAA while providing all radiation patterns; and a fixture to measure the 3-D radiation pattern which is compact and provides low interference on antenna's radiation pattern.
