Title: Small-sized slot antenna
Inventor: TSUNEKAWA KOICHI
IPC: H01Q13/16
Filed: 1987-01-23
Abstract: PURPOSE:To form a small-sized slot antenna with a cavity resonator having two resonance points by forming each surface with a metallic plate, prescribing the length of each side, setting two points of edge part in the width direction of the slot having prescribed dimensions, which are opposite each other, as feeding points and prescribing the difference of lengths from the feeding points to the edges of the slot in both directions. CONSTITUTION:The slot, folded in S-shape, whose total length is about 35 cm(1.05 wavelength) is formed on the cavity resonator 13 whose length 16 is 8 cm(0.24 wavelength), width 17 is 18 cm(0.54 wavelength) and height 18 is 1.5 cm(0.045 wavelength) and the difference between the lengths of right and left slot 14 and 15, seen from the feeding points, is set in 1.0 cm(0.03 wavelength), then resonance frequencies are 903 MHz and 942 MHz. It is desirable that width is about 0.4-0.8 wavelength and length is about 0.2-0.5 wavelength in terms of the sides of the resonator. As for the total length of a slot, a practical upper limited value is about two wavelengths because the characteristic is deteriorated by means of mutual actions and the impedance seen from the feeding point becomes small if the space between the facing slots is set too small.
