10-83 (1880)). The figure (A) is 174
It is a bent wavelength whip antenna, and a linear radiation conductor element 2 is arranged in parallel on a ground conductor plate l, and its base is bent and connected to a coaxial feeder line 3. Since the resonant frequency of this antenna is approximately determined by the length of the radiation conductor element 2 and the distance between it and the ground conductor plate l, there is a drawback that it is difficult to form the antenna into a small size. In the figure (B), the end of the radiation conductor element 2 is grounded by a shorting pin 4, and a coaxial feed line 3 is connected to a point matching the impedance of the feed line for offset power feeding. In this case as well, the resonant frequency is approximately determined by the length of the radiation conductor element 2 and the distance from the ground conductor plate l, so that it has the same drawbacks as described above.
第８図は、放射導体素子２′を文工ＸＸ、の板状の導体
で構成し、これを支持台１１によって接地導体板ｌ上に
高さｈに保持したアンテナであり。FIG. 8 shows an antenna in which the radiation conductor element 2' is composed of a plate-shaped conductor manufactured by Bunko XX, and this is held at a height h on a ground conductor plate l by a support stand 11.

体素子２′と接地導体板ｌの距離（アンテナ高ｈ）を大
きくする必要があり、低姿勢なアンテナであるという利
点が損なわれる欠点がある。It is designed to resonate at lx Jubun 2 Oniri/4 (λ is the wavelength). This allows the length of the radiation conductor element 2' to be shortened, making it easy to downsize, and having a low profile and high practicality. However, the bandwidth of this antenna is proportional to the distance between the radiating conductor element 2' and the ground conductor plate 1, so in order to realize a broadband antenna, the distance between the radiating conductor element 2' and the ground conductor plate l must be (Antenna height h) needs to be increased, which has the disadvantage that the advantage of having a low-profile antenna is lost.

とができるが、放射特性としては、広帯域アンテナとて
充分に動作することができないという欠点がある。To compensate for this drawback, a multi-resonant antenna as shown in FIG. 9 is used. In this method, two plate-shaped radiation conductor elements 12 and 12' are arranged on a ground conductor plate 1 in parallel with each other through a dielectric plate 6, and one end thereof is connected to a ground conductor plate l by a shorting pin 4. Short-circuited, plate-shaped radiation conductor elements 12 and 1
One side of 2' is short-circuited by a short-circuit plate 5, and a feed line 7 of the coaxial feed line 3 is connected to a feed point on the short-circuit plate 5 to supply power. This antenna operates as a multi-resonant antenna using the two plate-shaped radiation conductor elements 12 and 12', and can provide an equivalent wideband antenna. This antenna consists of a plate-shaped radiation conductor element 12.12'
Since the distance between the radiating conductor element 12 or 12' and the ground conductor plate l is very small compared to the wavelength, a minute monopole mode due to the feed line 7 and a slot mode formed by the plate-shaped radiation conductor element 12 or 12' and the ground conductor plate l are generated. However, since a part of the slot mode opening plane between the plate-shaped radiation conductor element 12' and the ground conductor plate l is closed by the shorting plate 5,
There is a serious drawback that there is a difference in antenna gain between the radiation characteristics of the plate-shaped radiating conductor element 12 and the radiation characteristics of the plate-shaped radiating conductor element 12'. Therefore, although it can operate as a wideband antenna in terms of impedance due to its multiple resonance characteristics, it has the disadvantage that it cannot function satisfactorily as a wideband antenna in terms of radiation characteristics.

A current flows through the periphery, and the electric potential at one point on the periphery further supplies power to the additional conductor plate 9 via the short-circuit conductor 10, so that the additional conductor plate 9 also operates as a radiating element. Thereby, the additional conductor plate 9 and the plate-shaped radiation conductor element 12 operate in a staggered manner, thereby making it possible to widen the band of impedance characteristics.
