Abstract

An antenna comprises a square printed circuit board. On one side antenna elements 7, 8, 9, 10 are printed. Each of these comprises an arcuate action which together with linear actions provides a hollow triangle. The other side of the board is provided with resistors, capacitors and inductors, the two sides together forming the complete circuit (Fig. 4 not shown). <IMAGE>

Description

SPECIFICATION Electronic antenna SUMMARY OF THE INVENTION This invention relates to an electronic antenna which has a structure of the preset printed circuit board (PCB) as the main body of receiver of the electronic antenna which is connected with a feeder wire to the antenna terminals of TV set (or other receiver) to receive a distinct picture without using any outdoor antenna (but it needs a specific direction).

BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is the perspective view of the practice of the invention.

Figure 2 is the view of electronic parts arrangement of the invention.

Figure 3 is the view of the printed circuit board of the invention.

Figure 4 is the view of the circuit of the invention.

DETAILED DESCRIPTION OF THE INVEN TION: The invention offers a multi-directional and indoor electronic antenna, of which shape please refer to Fig. 1.

The inner part of the present indoor TV (or other receivers) antenna 1 is equipped with a preset printed circuit (P.C.) board 4 arranged with electronic parts therein. The printed circuit on the P.C. board 4 is shown in Fig. 3.

And the other side of the P.C. board 4 is mounted with the electronic sets shown in Fig. 3, and they are composed of the main body of the present invention, the electronic antenna shown in Fig. 2 s 3. We merely connect the feeder wire 6 on the terminals 5 on the P.C. board 4 to the antenna input terminals of a TV receiving set (or other receivers), and can obtain a distinct picture of the programs. As shown in Fig. 1, it is convenient and withou using the prevailing fixed directional receiver, and can save installation and maintenance fees as the outdoor antenna. It can be free from any unconvenience and trouble when in bad weather (such as typhon), but also prevent from the likely accident of falling down of the outdoor antenna owing to bad weather or other courses.

It is indeed a novel and practical structure.

As shown in Fig. 3, the structure of the main body of the electronic antenna 1 has a piece of P.C. board 4 of which 4 corners are connected with the same circuit on each corner respectively, and it is consisted of a section of a round arc of copper foil and an acute shaped copper foil which is connected to the former. In the center of the acute shaped copper foil has a triangle opening, and constitutes the main body of the dual purposed outdoor and indoor antenna by means of the specially designed shape of copper foil shown in Fig. 3 to receive TV (or other) channels of the waves. It can be merely use a single feeder wire to connect with the antenna input terminals of a TV receiver (or other receiver) to prevent any trouble arising from the fixed direction of the outdoor antenna, and catch a distinct picture of the programs.

The functional theory of this electronic antenna as shown in Fig. 2, 3, and 4, is multiplying the wave signals received by the wave receiving circuit 7 and the wave signals received by the wave catching circuit 8 for multiplying the signals to make the circuits 9 and 10 without aiming to the direction of wave transmittance. However, these two sets of signals are jointly transmitted to the antenna input terminals of TV (or other receiver) through the terminals 5 and the feeder wire 6. Thus, the doublly amplified signals is transmitted to the amplifier of a TV receiver for amplifying in order to improve the defect of the prevailing outdoor or indoor antenna which can only receive the wave signals which directly transmitted to the receiver with a blurred picture.

An electronic antenna is equipped with a piece of P.C. board of which 4 corners are connected with a section of arc shape of copper foil, and printed on each corner respectively, and its outside has an extended piece of hollowed triangle copper foil in the symmetrical positions at these 4 corners; by the combination of these copper foils, resistances and capacitors arranged on the 4 corners, a pair of wave receivers on the left side, the similar pair of the wave receivers on the right side, two wave receivers at the left side amplifies received wave doublly, too; furthermore, the two sets at the right and left sides wave receivers are preset symmetrically, and combined with a feeder wire in transmitting the signals to the antenna input terminals of the receiver (such as TV receiver) to obtain a distinct picture as the characteristics of the structure of the electric antenna.
