Patent number: 10199747Abstract: An antenna includes a radiator, a first feeding portion, a second feeding portion, a first grounding portion, a second grounding portion, and a loading portion. The radiator is parallel to the base board to radiate signals. A first end of the first feeding portion is electrically coupled to a central position of the radiator. A second end of the first feeding portion receives a first feeding signal to generate a first radiation pattern. A first end of the second feeding portion is electrically coupled to a first corner of the radiator. A second end of the second feeding portion receives a second signal to generate a second radiation pattern. The first grounding portion is electrically coupled between a second corner of the radiator and a ground plane of the base board. The second grounding portion is electrically coupled between a third corner of the radiator and the ground plane.Type: GrantFiled: July 31, 2017Date of Patent: February 5, 2019Assignee: NANNING FUGUI PRECISION INDUSTRIAL CO., LTD.Inventors: Tsung-Ching Lin, Liang-Hsien Hung

Patent number: 8711971Abstract: An exemplary MIMO transceiver includes a first transmitting channel and a second transmitting channel. The first transmitting channel includes a first power amplifier and a first transmission line which are connected together in series. The second transmitting channel includes a second power amplifier. A common terminal of a first single pole double throw (SPDT) switch is connected to the second power amplifier. A first terminal of the first SPDT switch is connected to the first power amplifier through a second transmission line. A common terminal of a second SPDT switch is connected to the second power amplifier. A first terminal of second SPDT switch is connected to the first power amplifier through a third transmission line. A second terminal of the second SPDT switch is connected to a second antenna. The first power amplifier, the second transmission line, and the third transmission line cooperatively act as a balance power amplifier.Type: GrantFiled: April 17, 2013Date of Patent: April 29, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Liang-Hsien Hung

Patent number: 7995970Abstract: A wireless transceiver includes an antenna, a filter, a radio frequency (RF) signal processing circuit, a shared amplifying circuit, a first switch circuit, a second switch circuit, a sending power amplifier, and a single-pole double-throw (SPDT) switch. The filter is connected between the antenna and the SPDT switch. The RF signal processing circuit outputs a first control signal when the antenna is utilized to send RF signals, and outputs a second control signal when the antenna is utilized to receive RF signals. The first switch circuit is connected between the shared amplifying circuit and the sending power amplifier, and switches on according to the first control signal. The second switch circuit is connected between the shared amplifying circuit and the SPDT switch, and switches on according to the second control signal. The SPDT switch selectively connects the filter to the sending power amplifier or the second switch circuit.Type: GrantFiled: April 20, 2009Date of Patent: August 9, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Liang-Hsien Hung, Mao-Chang Chuang
