摘要： A compact single-to-balanced bandpass filter is proposed in this invention. Firstly, a pre-design circuit is presented, which is composed of an inductive coupled-line (ICL) bandpass filter and an out-of-phase capacitive coupled-line (CCL) bandpass filter. A novel compact circuit with three coupled lines configuration, derived from the pre-design circuit, is then proposed for miniaturizing the single-to-balanced bandpass filter. In order to verify the feasibility of the proposed structure, a 2.4 GHz multilayer ceramic chip type single-to-balanced bandpass filter with size of 2.0 mm×1.2 mm×0.7 mm is developed. The filter is designed by using circuit simulation as well as full-wave electromagnetic (EM) simulation softwares, and fabricated by the use of low-temperature co-fire ceramic (LTCC) technology. The measured results agree quite well with the simulated. According to the measurement results, the maximum insertion loss is 1.65 dB, the maximum in-band phase imbalance is within 3 degrees, and the maximum in-band magnitude imbalance is less than 0.32 dB.

The straight section has a signal feed point located at a lower end thereof being connected to a signal source for feeding in an antenna signal. The first coil length determines a high-frequency resonant frequency of the dual band helical antenna, and a total length of the first and the second coil length determines a low-frequency resonant frequency of the dual band helical antenna. The straight section includes a diametrically expanded section to increase a high-frequency bandwidth of the dual band helical antenna.

摘要： An antenna has a central core with a central coupling region. A pair of helix antenna lines is formed a surface of the central core. A balun transformer is formed on a circuit board and electrically coupled to the pair of radiating antenna lines. Wherein, the circuit board has a protruding structure to affixing into the central coupling region of the central core. A signal input/output (I/O) end of the antenna is at another end of the balun transformer. The balun transformer preferably uses the LC resonators in two paths with a desired equivalent resonant length, so as to preferably produce the difference by half wavelength.
