Abstract
An embodiment of the invention discloses a circularly polarized patch antenna for medical detection. The antenna can help solve a technical problem that a conventional circularly polarized patch antenna is complex in structure, large in integration difficulty, high in cost and large in size and has no directing property. The circularly polarized patch antenna for medical detection disclosed in an embodiment of the invention comprises an oval patch, a microstrip feed line, a single layer double face PCB board and a grooved floor, wherein the microstrip feed line is connected to an outer periphery of the oval patch in a protruding manner; the grooved floor comprises a hollowed oval groove and a rectangular patch, the rectangular patch is arranged in the oval groove in a concaved manner, the oval groove and the oval patch form a ring seam which can be used for capacitor loading, and the oval patch and the rectangular patch are coupled to form a short circuit for inductance loading.
Description
Technical field [0001] The invention relates to the field of antennas and microwaves, in particular to a circularly polarized patch antenna used for medical detection. Background technique [0002] With the development of modern communication technology, pure linear polarization is difficult to meet the communication requirements. The circularly polarized antenna can receive incoming waves of any polarization, and its radiated waves can also be received by the antenna of any polarization. It has rotatory orthogonality and can suppress cloud and rain interference and resist multipath reflection. [0003] Microstrip circular polarization antennas combine the advantages and characteristics of microstrip antennas and circular polarization antennas, so they are widely used in wireless applications, such as measurement, communications, satellites, aerospace, global positioning systems, and RFID systems. The development of communication, remote control and telemetry technology. [0004] A...
