Substrate Integrated Meandering Probe-Fed Patch Antennas for Wideband Wireless Devices

This paper presents novel linearly polarized (LP) and circularly polarized (CP) patch antennas for wideband wireless devices. Advanced electrical characteristics of the antennas including wide bandwidth, low cross polarization, low back radiation, and polarization insensitivity contribute to improve the signal quality of wireless connectivity. It is a realization of antenna foundation by employing multilayer microwave laminates to form a substrate integrated meandering probe-fed patch antenna. First, a design and analysis of the proposed patch antenna for LP operation is carried out. Based on the obtained results of this LP element, a substrate integrated meandering probe fed CP patch antenna is exhibited afterward. This paper is considered as a part of RF modules that could be integrated with other components like sensors, Microcontroller units, and electronic parts to form a wireless product by means of conventional packaging process.
