Abstract: A multi-segmented planar antenna with a built in ground plane and method of forming the antenna are described. The antenna elements are formed on a layer of first dielectric having conducting material on both the first and second sides of the layer of first dielectric, such as a printed circuit board. Antenna elements are formed on both sides of the layer of first dielectric using selective etching of the conducting material. Two antenna elements are generally rectangular separated by a narrow gap and electrically connected by two shorting strips across the gap. Two antenna elements are long and narrow wherein the length of each is an integral multiple of a quarter wavelength of the operating frequencies of the antenna. A layer of second dielectric is placed between the layer of first dielectric having the antenna elements and a ground plane. The antenna can be fully encapsulated in a plastic encapsulation material.

Abstract: Antennas and methods of forming the antennas having a very low profile and a built in ground plane are described. The antenna elements are formed of conducting material on a layer of dielectric material, such as an integrated circuit board.

In other embodiments the antenna elements are formed on both the top and bottom surfaces of the layer of dielectric material. The self contained ground plane makes the antenna performance independent of proximity to conducting or non conducting surfaces.

Abstract: An antenna is formed from two antenna elements, a first antenna element and a second antenna element, wherein the second antenna element surrounds the first antenna element. A shorting element electrically connects the inner antenna element to the outer antenna element. An insulating gap insulates the inner antenna element from the outer antenna element except for the region where the shorting element connects the two antenna elements. A coaxial cable connects the antenna to a transceiver. The inner conductor of the coaxial cable is connected to the first antenna element and the outer conductor of the coaxial cable is connected to the second antenna element. The length of the outer perimeter of the first antenna element is equal to an integral multiple of one quarter of the wavelength of the center frequency of the antenna. The inner antenna element can be rectangular, square, circular, oval, or any similar shape. More than one antenna can be formed on a single layer of dielectric material.

Abstract: An antenna that can be used as an active receiving antenna and a transmitting antenna is formed by forming dual disk antenna elements. The dual disk antenna elements are formed by etching a pattern in a layer of conducting material, such as copper, formed on a substrate of dielectric material. One of the disks acts as the active antenna element and the other disk acts as a counterpoise antenna element. In one embodiment a RF amplifier chip is used to form an active receiving antenna. In another embodiment the RF amplifier chip is removed and the antenna can be used either as a receiving antenna or a transmitting antenna. In another embodiment a RF amplifier chip is used with an electronic switch to include the RF amplifier chip when the antenna is used as a receiving antenna and to switch the RF chip out of the circuit when the antenna is used as a transmitting antenna.
