て加工することは非常に有効である。 In the one-end short-circuited rectangular microstrip antenna shown in Figure 2, there is an air layer between the strip conductor 2 and the ground conductor 1, so the length L resonates at about one-fourth of the free space wavelength. , radio waves are radiated in a direction perpendicular to the ground conductor 1. In such a rectangular microstrip antenna with one end shorted, it is very effective to bend and process a thin metal plate from the viewpoint of production cost and production time.

However, when constructing a microstrip antenna using a thin metal plate, distortion occurs due to insufficient strength, and the distance D between the strip conductor 2 and the ground conductor 1 is not uniform, resulting in changes in the resonant frequency and input impedance. There was a problem that variations occurred.

FIG. 1 is a diagram showing a microstrip antenna according to an embodiment of this invention.
1 is a ground conductor, 2 is a strip conductor arranged parallel to ground conductor 1, and 3 is ground conductor 1 and strip conductor 2.
These are short-circuiting plates that short-circuit each other, and are similar to those shown in FIG. 4 is a bent portion of the strip conductor.

数の変化は無視できる。 The one-end short-circuited rectangular microstrip antenna configured as described above has increased strength in the length L direction compared to the conventional one in which both sides of the strip conductor 2 are not bent. Therefore, variations in resonance frequency and input impedance also become smaller. Furthermore, since the width W does not have a large effect on the resonant frequency, changes in the resonant frequency due to structural differences such as the presence or absence of bending can be ignored.

度は90°以上であればいくらでも構わない。 In the above embodiment, both sides were bent by 90° to the side opposite to the ground conductor, but the bending angle may be any angle as long as it is 90° or more.

As described above, according to this invention, the extremely simple structure of bending both sides of the strip conductor 2 has the advantages of increased strength, reduced distortion, high precision, and small variation in characteristics. It has the effect of
