“…There are three basic techniques for feeding a patch antenna. These include (1) direct feeding [12,13] such as coaxial, edge, or inset, (2) aperture coupling [14][15][16], and (3) proximity coupling [17,18]. For the proposed layer stackup in Figure 1, the aperture coupling technique offers the combined advantages that the antenna can be fed from underneath the ground plane (the ground plane also acts as a shielding layer) through an impedance controlled microstrip line and that no vias are required for galvanic contact of the patch antenna.…”

Three patch antennas suitable for integration and operation in a compact 24 GHz wireless sensor node with radar and communication functions are designed, characterized, and compared. The antennas are manufactured on a low loss glass wafer using thin film (BCB/Cu) wafer level processing (WLP) technologies. This process is well suited for 3D stacking. The antennas are fed through a microstrip line underneath a ground plane coupling into the patch resonator through a slot aperture. Linear polarization (LP), dual mode (DM) operation, and circular polarization (CP) are achieved through the layout of the slot aperture and rectangular patch dimensions. Antenna gain values of ∼5.5 dBi are obtained in addition to the 10 dB impedance bandwidths of 900 MHz and 1.3 GHz as well as 500 MHz CP bandwidth with a 3 dB axial ratio for the LP, DM, and CP patch antennas, respectively.

“…, cross‐slot is used for CP operation. The cross‐slot, fed by an inclined microstrip feed‐line or a series microstrip feed‐line , excites two orthogonal linearly polarized modes with equal amplitude and a 90° phase difference. In point‐to‐point communication systems for underground environments, identical circular polarization in the front and back of the radiating antenna is important in avoiding the undesired polarization mismatch.…”

In this article, we have proposed a multilayer bidirectional circularly polarized antenna for underground communications. The proposed antenna consists of two slot-coupled back-to-back arranged rotated patches and a microstrip feed-line. Identical left-hand circular polarization is achieved in both front and back directions to avoid the undesired polarization mismatch for point-to-point connection. A prototype of the proposed antenna is built to validate the design strategy. The measured data, including S-parameter, axial ratio, radiation pattern, and gain, agree well with the simulation results.
