Title: Surface mounted circular polarization antenna and radio equipment using the same
Inventor: MIYATA AKIRA
IPC: H01Q13/08
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide the antenna capable of being miniaturized and surface- mounted and easy in adjustments of characteristics by forming a rectangular or elliptic radiation electrode nearby across the open end or side edge part of a tip open type microstrip-shaped feed electrode and a gap. SOLUTION: On one main surface of a base body in a flat plate shape formed of a dielectric, the rectangular radiation electrode 3 and the microstrip-shaped feed electrode whose one end is open are formed and almost entirely on the other main surface, a ground electrode 6 is formed. When a signal is inputted from a signal source 8 to the feed electrode 4, the signal is inputted to the radiation electrode 3 through the gap 5 by electromagnetic coupling. This inputted signal enters a resonance state in two diagonal directions. At this time, tow resonance currents ia and ib have their directions orthogonal and are 90 deg. out of phase with each other. Consequently, currents radiated from the two resonance currents ia and ib become 90 deg. -out-of-phase linear polarized waves, which are put one over the other to generate a circular polarized radio wave.

Filed: 1981-09-14
Abstract: PURPOSE:To perform the shaping of pulse without any malfunction and fluctuation of pulse width, by setting forcibly the threshold level at 0 in case there is no input pulse signal for a certain period. CONSTITUTION:The 2nd peak wave detecting circuit includes a comparator 8, a diode 9, a capacitor C2 and a resistance R4. A time constant is set between the C2 and R4 as C2.R4<<C1.R3. No next pulse is fed after the preceding pulse is fed to an input terminal IN, and the output V3 of the 2nd peak wave detecting circuit is less than the threshold value VTh1 of a comparator 10. As a result,  the comparator 10 is set at a high level to turn on a transistor 12. Then the charging and discharging circuits C1 and R3 of the 1st peak wave detecting circuit are discharged, and the output of the 1st peak wave detecting circuit, i.e.,  the threshold level VT is forcibly set at 0. As a result, an automatic threshold  value controlling circuit can perform the peak wave detection of the amplitude  although the amplitude of the next input pulse is extremely reduced. At the  same time, the optimum threshold level can be automatically set.
