In this paper the design and the results of the investigation into the performance of an embeddable antenna module for civil engineering applications are presented. The module consists of a rectangular microstrip patch antenna, a microstrip inset feed, electronic components such as a rectifier circuit and a protective housing. The housing is used to protect the antenna, the feed and the electronic components from the physical, chemical and electromagnetic influence of the surrounding material. First, a conventional transmitting mode approach is used to analyze and optimize the antenna to operate at ~2.5 GHz when embedded in concrete. Then, a receiving mode approach is used to investigate the performance of the embedded antenna module for two different external sources of excitation; namely, a plane wave and a second antenna in free space. It has been shown that by choosing the appropriate dimensions and dielectric property of the housing, the influence of the concrete on the resonant frequency and the magnitude of the reflection coefficient has been reduced. The feasibility of the embedded antenna module along with a rectifier circuit for a wireless microwave power transmission inside concrete has been demonstrated. The simulation and measurement results obtained with early-age concrete mimicking substance using two-antenna setup are in good agreement. The antenna module can be used for wireless power transmission through building materials such as concrete and for material characterization.

“…In [9] the characteristics of a microstrip patch antenna was investigated at 2.4 GHz when the antenna was embedded within concrete. In our research group studies on the characteristics of an embedded microstrip patch antenna at 2.45 GHz were performed [10][11][12]. In [13] the prospects of beaming wireless power to an antenna embedded inside concrete was studied at 5.7 GHz.…”

Abstract-Efficient embedded antennas are needed for future wireless structural health monitoring. The input return loss and transmission losses of a dipole, a planar inverted-F antenna (PIFA), a microstrip patch, and a loop antenna are studied at around 2.45 GHz when these antennas are embedded inside a concrete cylinder. Antenna performance is investigated in free-space, in air dried concrete and in saturated concrete with and without the presence of steel reinforcements. It is observed that the maximum transmission loss for a distance of 250 mm between antennas is around 50 dB which is acceptable for inside the bridge wireless communication between sensors.

“…The air-box was added because we observed through simulations and experimentations that when the RX helix and load loop were inside the air box, instead of touching the concrete, the Q factor as well as the power transfer efficiency improve significantly. In addition, similar configuration to our air box was used by [70], where an air-gap was added on top of patch antennas embedded in concrete in order to optimize their performance. Practically, the air box around the RX helix and load loops can be implemented by using appropriate packaging.…”
