The Study of a Novel Patch Antenna Sensor
نویسندگان
چکیده
In order to improve the bandwidth of the traditional patch antenna, a new antenna sensor based on the U-slot antenna was designed in this paper. The electromagnetic simulation software Ansys-HFSS was used to analyze the impact of the antenna parameters, and short circuit loaded half U-slot antenna with a slot ground plane was designed at last. The main bandwidth of the antenna sensor ranges from 670 MHz to 839 MHz, while the dimension of the sensor is small enough. The size of the antenna patch is just 70×42 mm. Although the directivity of the antenna is not good enough, it can be used to detect the ultra high frequency electromagnetic signals emitted from partial discharge sources in the power transformers.

متن کاملModified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...
