かつ特性のすぐれたパッチアンテナに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a patch antenna that is compact, lightweight, and has excellent characteristics that are suitable for mobile bodies and portable wireless devices.

It is formed by etching one side of a stripline material having copper foils 3 on both sides, thereby removing the disk 1, leaving only the portion of the disk 1. 4 is an antenna feed line connected to point a of the Korean projector 1.

ようにしたものである。In FIG. 1, a TM, . Assuming that the electromagnetic wave is excited in this mode, the electromagnetic wave is radiated upward and has a vertical plane directivity characteristic as shown by the dotted line A in FIG. However, from an applied perspective,
Do you want to have sensitivity or directional characteristics in the side and lateral directions?
Alternatively, control of the directional characteristics may be necessary, such as when it is necessary to suppress reflections on one side and remove unnecessary interference. In order to solve these drawbacks, the present invention provides an auxiliary competitive firing control body close to the stripe firing body to control the directivity in the vertical plane to a desired shape.
第３図は本発明の実施例を示す構成図で、前記説明と同
一のものには同一の符号を付してある。FIG. 3 is a block diagram showing an embodiment of the present invention, in which the same components as those described above are given the same reference numerals.

成を示している。The width of the reflection control body 5 along the B-B' axis is designed to be approximately ^/4, assuming that the propagation wavelength in the neck body 1 is input. Therefore, when the end 6 is open, the end 7 on the side of the mirror projector 1 can be regarded as a short circuit in terms of high frequency, that is, a ground point. Note that if this width is sufficiently wide, a magnetic current with an amplitude of 2V will flow over the gap 8, where V is the voltage between the gaps. Therefore, the mirror electric field of the mirror projector 1 is trapped between the mirror projector 1 and the gap 8, and is difficult to radiate into the external space. Therefore, the cervical electric field is strong on the side opposite to the fin control body 5 and weak on the side of the fin control body 5. Therefore, the axis of the cervical radiation in the vertical plane is oriented from the vertical direction like the axis 9, and the reflection direction is controlled as shown by the dotted line C in the vertical plane. The amount varies depending on the size of the gap 8 and the shape of the Korean shooting control body 5. FIG. 4 is a plan view showing another embodiment of the present invention, showing a structure in which the width of the Korean firing control body 10 is constant and the vertical directionality is controlled by changing the gap 11.
図において、ギャップ１１は韓射体１の円周に沿って下
側が狭く、上側が広く変化しているので、Ｘ−Ｘ′軸に

ごとく、本発明は鰭射制御体を同一基板上に鰻射体とと
もにエッチングして形成することにより、垂直面指向性
を制御することができ、またこの構成は極めて経済的に
実現できるので、その効果は大きい。In the figure, the gap 11 changes from narrower at the lower side to wider at the upper side along the circumference of the Korean projector 1, so it is also possible to make it asymmetrical with respect to the X-X' axis. As explained above, according to the present invention, vertical directionality can be controlled by etching the fin ray control body and the fin ray body on the same substrate, and this configuration can be realized extremely economically. Therefore, the effect is large.
更に本発明は垂直面指向特性を制御しているので、携帯
無線装置のアンテナとして、不要干渉の影響を受けにく
く、目的とする方向に指向性利得が得られる効果がある
。Furthermore, since the present invention controls the vertical plane directivity characteristics, it is less susceptible to unnecessary interference when used as an antenna for a portable wireless device, and has the effect of providing directivity gain in the desired direction.
