Abstract

A dielectrically-loaded antenna for operation at frequencies in excess of 200 MHz includes an antenna element structure disposed on a high dielectric constant core, which element structure comprises a pair of laterally opposed groups of helical antenna elements. Each group comprises first and second mutually adjacent elements, of different thicknesses providing looped conductive paths on the antenna, formed by the first elements of each group and the second elements of each group respectively, which resonate at differing respective resonant frequencies to yield a relatively wide operating bandwidth. The helical elements of each group define, between them, part of an elongate channel which has an overall electrical length in the region of n λ/2 within the operating frequency band to provide isolation between the looped conductive paths. The major part of each such channel is located between the elements so as to minimise intrusion with other parts of the antenna.

Two of them = the electrical length of one ballast in the other path 2 at the coupling frequency of the line to the line extending around the mandrel is larger than the use of a fork antenna element, which is larger. The way to achieve this is to share The four sides of the dielectric mandrel and 70 pieces have a separate part, which extends at a position. The antenna weighs unbalanced converter sleeves with branches of different electrical lengths between the edges. Flat = at least one of the pieces The separated part of the part has a slit extending longitudinally, such as the unbalanced converter sleeve is separated, which is normal, so the conductive path of the two sleeves is the same as the conductive material in the sleeve. The configuration is not balanced: ^ Provides insulation capacity, so the formation of two bands For the quarter - wave "value converter converts the length of the slit so as to electrically separate the length (λ / 4), part of the square edge insulation provided by the sleeve apart from each other in the operating point impedance.

Description of the invention (2) As each conductive path resonates at different frequencies, it provides Antenna with fairly wide frequency band. One problem with the antennas described above is that it is difficult to incorporate a slot of sufficient length into the sleeve to provide a quarter wavelength, especially when the sleeve is relatively short. The L-shaped slit proposed in G B 2 3 2 1 7 8 5 A is difficult to manufacture and limits the current in the sleeve. [Objective of the Invention] According to the first design concept of the present invention, the present invention provides a dielectric load loop antenna that operates at a frequency greater than 200 MHz and includes an electrically insulating mandrel formed of a solid material.

These elements have different electrical lengths within the operating frequency band of the antenna, and are fed in The corresponding first end of the coupling region is coupled, and the corresponding second end is coupled by a connecting conductor extending around the mandrel. Therefore, the extension elements of each group form at least a part of an extension channel. The frequency band is in the region of η λ / 2 and its main part is located between the elements, and the first elements of the two groups form a first coupling conductive path portion, and the first The two elements form part of the second coupling conductive path, so that the path has a corresponding resonance frequency in the frequency band, and extends from the feed link to the link guide It, and then returns to the feed link.

The entire channel is configured with an electrical path, of which the other path has a mobile phone connection for the antenna. The quarter-wave longitudinally extending feed of the conductor is composed of an integrally connected conductor, and each body can be positioned on the end face of the core under the structure of an antenna feeder. Common extension, between spaced positions "For other design concepts and better characteristics, please refer to Patent Application No. 2 or slits to provide insulation between the electrical loops formed by antennas and line elements. Because the main parts of this channel are located between 'It can reduce interference to other parts of the antenna. It is located between the antenna elements. The antenna element and the connecting conductor to form at least two loops of the two paths are controlled by one way and the thunder length is greater than the lifetime of the antenna operating frequency.

490882 V. Description of the invention C5) The antenna includes an electrically insulating mandrel of solid material, the corresponding dielectric constant of the material is greater than 5, a feed connection, and a disposition on the outer surface of the mandrel or adjacent thereto. The antenna element structure includes a first and a second pair of antenna elements, wherein the arrangement of each pair of elements is actually opposite to each other at both ends of the diameter. 'The material of the mandrel occupies the main part of the volume formed by the outer surface of the mandrel, -And form the main part of the second pair, so its width is wider than that of the first pair of elements. This antenna is particularly suitable for receiving circularly polarized signals, such as those transmitted by the Global Positioning System at 155 MHz. This antenna is usually configured so that it has two element pairs, with one element having a longer element than the other. Different lengths produce relative differences to receive circularly polarized signals. Because the second pair _ described above in relation to the present invention is wider than the first pair, the electrical length of the second pair is longer than the electrical length of the first pair (even the two actually have actual lengths). ^ Receiving antennas that are not similar to the above-mentioned GP S type, in which the actual lengths of the antennas are different, and the antennas proposed in the article can be produced with substantially the same length to prevent the shape of the components from being too complicated or coupled with the conductor. [Preferred Embodiment] Referring now to FIG. 1, a relatively good antenna of the present invention has an antenna element structure including a single pair of side-to-side antenna groups 10 A Β and 10 C φ D. Each group contains an elongated antenna element 10 A, 10 B, 10 C, 10 D, which are adjacent to each other and generally parallel. These antenna elements are placed on the cylindrical surface of the antenna cart 1-21. The mandrel 12 has an axial channel 1 4 which has an internal metal lining which frames the axial internal feeder conductor 16 surrounded by a dielectric insulating sheath 17. The inner conductor 1 6

Page ί 490882 5. The invention description (6) and the lining together form a feeder structure 18 to couple a feeder line to the antenna element 1 at the feed position on the end surface 2 D of the mandrel] 2. A-1 OD. The antenna element structure includes corresponding radial elements 10AR, 10BR, 10CR, 10DR, which are formed as a metal conductor on the end surface 12D, wherein the first end of the end surface connection element 1 0A-1 0 D is Feeder structure. In this embodiment, the axially extending elements 10 A- 10 D and the radial elements have approximately the same actual length, and each element is of an elongated spiral type. It has a half-circle around the axis of the mandrel 12. Each antenna element group includes first elements 10A and 10C and second elements 10B and 10D. The two groups of the first elements 10A, 10C are configured to have different electrical lengths for the second elements 10B, 10C of each group, considering that the width of the first element is wider than the width of the second element. It is important to understand that wide components can propagate signals faster than narrow components. In order to form a complete conductive circuit, each antenna element (10A-1 OD) is connected to the edge 20 U of a common virtual ground conductor, which is shaped like a proximal end portion surrounding the mandrel 12 as an extension element 1 0 A -10D connecting conductor. The sleeve 12 is in turn connected to the lining of the axial channel 14 via the end surface 12D of the mandrel 12. It is thus formed by any one of the first or second antenna element of the first group 10 AB, the edge of the sleeve 20U, and the corresponding first or second antenna element of the second group 10 CD. In any given transverse cross section through the antenna, the first and second antenna elements of the first group 10 A B are actually

On the corresponding first and second element planes, the ends on this plane that must be understood are actually configured with X and ζ φ of the standard axis. Shaft, and the mine guide table μ shown in Figure 1 does not come out. V electric suite 2 〇 Overlay + inserter structure 1 8, the core # = the closest part of the f mandrel 12, the metal lining surrounding the feed channel 14 is actually filled into the sleeve 20 and the axial connection Form an entire space that is not balanced. The signals in the sleeve 2 and the welded knot transmission line are in the device, so the feeder structure 18 is formed to change, wherein the cylinder 2 is between the unbalanced state and the balanced state. The upper end is centered on the nearest end of the antenna, and the equilibrium state is in the axial direction of the sleeve design. The axial position = axial position 1. In order to achieve this effect, the length of the lower layer makes the transmission device have a relatively low dielectric constant. 'Balanced unbalanced converter is about two 4 or 90 degrees in the operating band of the antenna. Because the mandrel material of the antenna has a short front, should be 1 and the annular space surrounding the inner conductor is filled with a relatively small dielectric constant, 纟 bar edge dielectric material, so the feeder structure at the end of the sleeve 丄 8 = ^ Short electrical length. As a result, the signal to 末端 at the end of the feeder structure i 8 is at equilibrium. As a result, the signal at the end of the feeder structure i 8 is at least and the force is balanced. Another effect of the sleeve 2 0 is that for frequencies at the antenna operating frequency, the edge portion 2 0 u of the sleeve 2 0 is insulated from the ground represented by the outer conductor of the feeder structure. This means that the current circulating between the antenna elements 丄 0-10 D is actually known at the edge. Therefore, when the antenna resonates in unbalanced mode, the sleeve acts like an isolation well. The first and second antenna elements of each group 10AB, 10CO are formed to have different electrical lengths at a given frequency. These antenna elements

490882 V. Description of the invention (8) The conductor loops formed have different electrical lengths. As a result, the antenna resonates at two different resonance frequencies. In this example, the actual frequency is uncorrelated across the width of the element. As shown in FIG. 1, the feeding connection area of the generally parallel elements in each group on the non-end face of the mandrel extends to the edge 2 0 U of the balun sleeve 2 0, thus forming an inter-element channel 1 1 AB, 1 1 CD, located between the elements of each sleeve. The length of the design channel is mainly to isolate the conductive path at the corresponding resonance frequency. This can be achieved by forming the channel at an electrical length of / 2 or ηλ / 2. At the resonance frequency of one of the two conductive loops, a standing wave is set over the entire length of the resonant loop, and the voltage values are equal at the adjacent ends of the λ / 2 channels. When the primary circuit resonates, the antenna elements forming the non-resonant circuit portion are isolated from adjacent resonant elements, because equal voltage at each end of the non-resonant element results in zero current. When other conducting circuits resonate, similarly, each circuit is isolated from the resonant circuit. In summary, at the resonant frequency of a conductive path, the path is excited while being isolated from other paths. Then at least two different resonances can be obtained at different frequencies. Considering that when a branch resonates, each branch will load the other conductive path to a minimum. In fact, one or more isolated low impedance paths can be formed around the mandrel. In the preferred embodiment, the entire channels 1 1 A B and 1 1 C D are positioned between the corresponding antenna elements 10A, 10B, and 10C, 10D. The channels can extend a relatively small distance into the sleeve 20, but the main part of the entire length of each channel 1 1AB, 1 1 CD is located between the antenna elements. Basically, for each channel,
