A multibending antenna structure includes a substrate, a microstrip antenna layer, and at least a decouple unit. The microstrip antenna layer is disposed on one side of the substrate. The microstrip antenna layer includes a plurality of radiation units which are respectively formed in a multibending shape and forming a concave area. The radiation units are sequentially connected to form an antenna array, and a plurality of antenna arrays are disposed in a transversely parallel arrangement, with an interval between each two neighboring antenna arrays. The decouple unit is disposed between the neighboring antenna arrays. When the input end of the radiation unit receives a signal input to emit an electromagnetic wave having a radiation energy, the half-power beam width thereof is increased.

Multibending antenna structure

A multibending antenna structure includes a substrate, a grounding layer, and a microstrip antenna layer. The ground layer and the microstrip antenna layer are disposed on two sides of the substrate. The microstrip antenna layer includes a radiation unit which is in a multibending shape and formed with a concave area. The length of the radiation unit is equal to 0.8 to 1.2 time the wavelength corresponding to an operation frequency. When the input end of the radiation unit receives a signal input to emit an electromagnetic wave having a radiation energy, the half-power beam width thereof is increased.

An antenna unit with anti-feed power divider function includes a first substrate, a second substrate, a microstrip antenna layer, a grounding layer, a microstrip wire layer and two vias. The microstrip antenna layer is disposed on an upper surface of the first substrate and has plural microstrip antennas and a high impedance wire connected to the microstrip antennas. The grounding layer is set on a lower surface of the second substrate. The two vias penetrates the first and the second substrates to electrically connect the microstrip wire layer and the microstrip antennas, wherein the two vias have different sizes. An antenna module thereof is also disclosed. The present invention precisely controls the power ratio and phase difference, utilizable for generating a symmetric and asymmetric feeding antenna array, thereby achieving a hierarchical feeding and minimizing the antenna structure.

A symmetric leaky wave antenna includes a dielectric substrate, an electric wall, and two reflection bore arrays. The dielectric substrate has a first and a second metal layers disposed on two opposite faces thereof. The first metal layer has a feed end and two travelling wave sides. The electric wall is disposed between two travelling wave sides, with the two travelling wave sides symmetrically disposed with respect to the electric wall. The two reflection bore arrays are symmetrically disposed along the two travelling wave sides, respectively, with the electric wall arranged at a central line between the two reflection bore arrays. The two reflection bore arrays pass through the first metal layer, the second metal layer, and the dielectric substrate. The reflection bore array and the electric wall reduce the leakage rate of the electromagnetic wave, thus increasing the gain value of the antenna.

Symmetric leaky wave antenna

A dual-notch antenna includes a radiation member and two microstrip lines. The radiation member is formed in a rectangular shape, with two first lateral sides disposed in opposite, and two second lateral sides disposed on two ends of the two first sides, respectively. The middle section of each first lateral side is concavely provided with a notch. Each notch has a feeding side and two cove sides, wherein the feeding side is disposed in parallel to the first lateral sides. The two cove sides are connected with two ends of the feeding side. Each microstrip line has one end thereof electrically connected with the feeding side of the corresponding notch, respectively.
