Description

2358520 IMPROVEMENTS IN TELEVISION ARRAY The present invention relates to

the television receiving arrays to extend to the directionless spherical antennas, satellite television and telecommunications.

The principal object of the present invention is to improve the tele vision array to receive the stronger signals to produce the clearer and finer pictures on the screen of the television receiver and to provide the simple, economical and practical means to instal the required directionless and effective array in the surroundings of the wet or rainy weather, indoor and hindering the reach of the direct waves or even extending to the long ra nge for satellite television and telecommunications.

To this end, according to one aspect of the invention, there is provided the parallel closer reflector and directors to the antenna or one or more conducting element or director of the general television receiving array to be closely installed to parallel to the antenna or dipole or arranged between the directors without any limitation and calculation of the distance in wavelength or length. All directors of this television receiving array may have the arrangement of the equal or unequal or both equal and unequal or shorter or different distance, the length of which may be about 1/8 of a wavelength or longer or even shorter without any calculation or ratio of the wavelength. The diameter or size or shape of the director is the same as the designed ones and the receiving antenna or dipole is a good conductor though the latter may be different.

This arrangement may prevent the dim and unclear pictures in order to 1 compensate the raindrops fallen down to the ground through the spaces between the directors or between the director and antenna or dipole to carry or reduce the weakened television signals or waves to cause the losses of gain just recei'vedfrom the farther or farthest directors of a directional television array and this installation of the television array may keep the receiving signals to reach the antenna or dipole to produce the enhancing waves to display the finer, clearer and more beautiful pictures on the screen of a television receiver in any kind of weather, especially during the rainy or wet weather.

According to other aspect of the invention, a smaller adequate concave or good conducting dish about several inches in diameter is arranged to be a reflector of an indoor television receiving array. The focus of this concave reflecting dish is the ideal point or position to instal the receiving antenna or dipole in 1/4 to 1/8 of the wavelength or any other size in combination with the foregoing arrangements of the closer or short distance for the installation of the directors without any limitation or calculation or a ratio of the wavelength to be an effective indoor Television Receiving Array used in any 5urrounding and any kind of weather. The size of this antenna or dipole with directors will entirely be corresponsively reduced to 1/4 to 1/8 of the wavelength or others. The required quantities of these short distance or closer directors may be adequately added and installed as the distance of the transmitter or Television Broadcast is far off accordingly and the size of the concave reflecting dish may follow the corresponsive reduction of the antenna in the ratio of the wavelength to obtain the gain. These closer directors may also be sealed with the light insulated paints or oils or resins or substances. On the other hand, this concave reflecting dish may be corresponsively enlarged or extended to an adequate size in the diameter or chord or ratio of the wavelength in combination with the out-door arrangements of closer or insulated or closer and insulated directors to be a rainy TV dish array for the long range transmission or space to earth transmitting and receiving requirements for the satellite televisions and telecommunications.

According to another aspect of the invention, the said directors and reflector of a television array may integrally be insulated or sealed by the light insulated paints, resins, oils or rapid dried insulated substances to prevent or reduce the reflecting waves or non-synchronizing ground waves of the same altitude from the multiple-paths or multi-paths to reach the receiving antenna or dipole to cause the ghosts of the pictures through the di- rectors one after another of a directional television array, the antenna or dipole of which is unsealed or opened to remain its conducting nature to receive the sky waves or signals from the reflection of the ionosphere or troposphere or the same strong higher direct waves just above the obstructions o hills or buildings. This closer arrangement with insulated directors and reflector may avoid the raindrops and multi-reflecting waves to interfere TV signals to reach a receiver to cause dim and ghosts displayed on pictures of a screen. This special improvement is arranged for the sky waves or higher ground waves just above the mountains or buildings or hills, the surroundings of which are hindering the reach of the direct waves or ground waves to the receiving antenna from the television broadcast or transmitter. The antenna or dipole of this TV array is preferably made of the flat or plane conducted plate, the plane surface of which is installed upwards to reduce the snow, confetti or coloured snow produced in the receiving antenna system or such circuits. Due to the television array is directional, the existence of the sealed directors and reflector may be the attenuations of the direct and reflecting waves on the same altitude and the Very High Frequency (VHF) or Ultra High Frequency (UHF) may have the natural ability to lead through the light insulated substances to enable these directional elements in contact with or conducting the effective waves of the higher altitude above the obstructions which hinder the reach of the direct waves of the television broadcast. On the other hand, the forward plane or flat plate antenna, directors and reflector made of the good conducting plates may be in lieu of the other usual ones of the television arrays to be the directional ones.

According to the further aspect of the invention, the spherical antenna made of one or two conductive sphere or ellipse or other forms or convex or -concave or plano-convex or plano-concave dish or semi-sphere or semiellip- se and the like may supersede the receiving element or antenna or aerial or dipole or folded dipole antenna of the television array to receive the waves or signals from all directions to be the directionless television receiving array in order to avoid the rotations of the directional ones for the tele vision broadcasts are not situating in the same course. These kinds of sphe rical arrays may be installed upwards or sidewards or forwards in combina tion with the foregoing arrangements of the rainy or closer directors and reflector of the television array and the sealed directors and reflector of an array may also be used to receive the sky waves or the higher groundwaves which have not been hindered by the obstructing bodies. The directional eff ect of the directors and reflector may assist the enhancing signals to reach the receiving antenna or element and the foregoing sealed mean may be emp loyed to seal the sideward or any part of this spherical antenna, in which the ghosts are produced within 90 degrees of the direct course of a televi sion transmitter or the directional TV array cannot get rid of the interfe rence of the ghosts or multi-reflecting waves. Other than the spherical an tennas fit for use in the areas of the reflecting and obstructing bodies, these may also be installed in the areas of multi-television broadcasts spreading in different courses of the broad open fields or plains.

This spherical antenna may be in lieu of the receiving element or dipole or folded dipole or antenna or aerial to be installed in the focus of the good conductive concave or dish reflector and fit for receiving the reflec- 4 - ting waves from the dish herein. There are more than two hundred kinds of the installations or connections of these spherical antennas to be in combination with the arrangements of the closer or insulated or closer and insulated directors and reflector to be a rainy television array or dish reflector array or indoor array used for all surroundings and weathers, the blowing winds of which may be prevented by the holes made on the dish or semi-sphere as described hereinafter. For a complete or integral sphere has no terminals forthe lead in transmission lines, therefore (1) A crack may be made to a half of the sphere to segregate the lowerpart to two equal convex ones, then the lower semi-sphere becomes two separate quar ters and the upper part is remained to be an integral semi-sphere. The whole sphere is now similar to be a folded dipole antenna. The diameter will be one wavelength or be reduced in the ratio of a wavelength of the receiving tele vision signals or waves. The lead in transmission lines may be linked withthe two terminals of the opposite sides of the downward crack of the sphere.

(2) Two equal conductive spheres or ellipses and the like may be installed to be the dipole or folded dipole antenna. The diameter may be the wavelength of the receiving signals in ratio or times. The lowest, opposite or adjacent or sideward points or lateral extremities of these two spheres may be arrangedto be the terminals of the lead in transmission lines to form the antenna. These spheres may be contact one another at a point of the circumferences or a piece of the same conductor is in contact with the tops or tips of these spheres or linked with the sideward or lateral extremities of the two spheres. Then the wavelength will be the length of these two diameters for the former and the wavelength of the latter may be the length of this conductor with two radii or two diameters. The terminals of the lead in transmission lines to form the folded dipole antennas may be arranged as the foregoing connections.

(3) One convex or concave or plano-convex or plano-concave dish or semisphere or semi-ellipse and the like may be installed upwards or sidewards or for- wards to be in lieu of any other antenna or in combination with the arrange--ments of the closer or insulated or closer and insulated reflector and directors of the television receiving array or dish reflector array. The two opposite or side or lateral points of the circumference may be arranged with adequate conductors to be the terminals of the lead in transmission lines or the connections of these spherical folded dipole antennas are the same as the foregoing installations. The chord or diameter will be the wavelength of the TV receiving wave or signal.

(4) Two convex or concave or plano-convex or plano-concave dish or semisphere or semi-ellipse may be installed forwards or upwards or sidewards to form the dipole or folded dipole antenna in lieu of any other or in combination with the arrangement of the closer or insulated or closer and insulated ref- lector and directors. The lateral extremities or sideward or adjacent or opposite or downward lowest points of the circumferences or mid-points of these forms may be arranged to be the terminals to link with the lead in transmission lines to form the dipole antenna. The tips or tops or mid- points or extremities or adjacent or opposite or contact points of these dishes or semi- spheres or semi-elIilses may be arranged to link with a piece of conductor or these two contact one another to form the folded dipole antennas and the terminals for the transmission lines and the length of the antenna may take reference to the foregoing descriptions.

Any one of these kinds of the spherical antennas exists a very wide area or surface for the receiving signals than the others to fit for the ideal directional or directionless requirements of the television arrays. The upward installations of one or two these forms are the special arrangements equivalent to the sphere or ellipses to form the effective directionless antenna in combination with the sealed closer reflector and directors with the light in- sulated substances. The series of these spherical antennas or TV spherical arrays may have the ideal effect in the surroundings of the multi-broadcasts or multi-paths of reflecting waves derived from the different courses or hindering the reach of the direct waves for all weathers except the severe winds which may be prevented by the holes on the adequate place or parts of the an- tenna. A successful and satisfactory installation of a spherical TV array may be chosen by the technician. At least, one directionless ideal and effective television receiving array for all weathers and surroundings will be standing with You and YoUr television receiver in every corner.
