“…The lowest gain, i.e., 0.42 dBi is found for the 2x1 patch antenna array presented in [45]. For 2, 4, 8, and 12 elements, the minimum obtained gain is 0.42 dBi (2x1 patches [45]), 2.1 dBi (2x2 patches [26]), 0.5 dBi (circular array of dipoles [79]), and 4 dBi (planar LPDA [59]), respectively. For 2, 4, 8, and 12 elements, the maximum obtained gain is 11.45 dBi (2x1 patches [25]), 14.8 dBi (4x1 patches [24]), 14.8 dBi (4x2 patches [33]), and 12.2 dBi (parasitic array of dipoles [65]), respectively.…”

This manuscript presents a survey of the existing literature on on-body antenna arrays. These can be used to enable wireless communication to and from different on-body nodes in a wireless body area network and are also used in medical applications. The design process and the required characteristics of on-body antenna arrays are discussed. On-body antenna arrays should be small, lightweight, and low-profile to ensure user comfort. The different types of on-body antenna arrays are discussed as well. On-body antenna arrays differ in the type of antenna element and in the geometric configuration of the array. The gain of the antenna arrays normalized to its area is compared and it is found that in the current state of the art this quantity reduces with increasing frequency from 36 dBi to 0.7 dBi. From our literature review, we draw important lessons that can be used to develop future on-body antenna arrays.

Based on the irregular undevelopable surface of the smart swimming goggles, an electric dipole conformal antenna array is proposed in this article. Through the simulation of the conformal antenna, the beam scanning area of the conformal antenna array is studied to achieve a wider radiation range. In addition, the signal strength loss of the conformal antenna in the underwater environment is discussed, and the monitoring method based on the signal strength is proposed, which is helpful for the positioning monitoring of the swimming goggles to achieve risk prevention and control of children drowning.

This paper presents a super wideband and high-gain log periodic dipole array (LPDA) antenna. The overall structure of the antenna was constructed using microwave studio computer simulation technology. The optimal sizes of the planned antenna are 39 × 10× 0.254 mm3. The engineered antenna arrangement is implemented on an RT5880 substrate as a dielectric medium. The LPDA is arranged in four arms that are equally spaced on both lines. The main 50Ω feeder line is partially grounded at the back of the substrate. A combination of circular director units is being studied and tuned in a regular pattern at a predefined distance from the antenna. An improvement in gain of 3 dBi is the response of the director units. The Conformist LPDA is adjusted to achieve a wide range of millimeter wave bands ranging from 40 to over 70 GHz. The antenna resonates at 60 GHz, where the maximum realized gain of 14.97 dBi is attained. The antenna was tested for utilization in the V-band involving wireless personal area network (WPAN) applications recommended by IEEE 802.11ad and IEEE 802.15.3c. The outcomes of the constructed antenna elements' tests and simulations agree fairly well. The proposed layout works better than previous efforts in this field.
