Portable communication device

An antenna assembly (100) includes a substrate (101) having a notched portion (103) and one or more attachment apertures (105). An antenna (107) includes a conductive coil (109) that is inserted within the slotted portion of the substrate (101) such that a loop of the conductive coil (109) is fastened within the attachment aperture (105) for holding the antenna (107) into a fixed position. The antenna assembly (100) for a low cost and easy method of assembly that rigidly attaches an antenna to a substrate without the need for additional mechanical fasteners.

Antenna assembly for a portable communications device

An antenna assembly (100) for use in a portable two-way radio communications device includes a radio housing (101) including one or more boss (103) used for securing portions of a substrate (105) to the radio housing. An aperture (115) located within an antenna housing (111) is positioned over an antenna boss (107) where a metal trace located on the substrate (105) can be electrically connected to the antenna housing (111) using a fastener (109). The antenna assembly (100) permits an antenna element (113) located in the antenna housing (111) to be easily connected to the substrate (105) using minimal component parts while fastening both the antenna housing (111) and substrate (105) into a fixed position.

Antenna assembly for use with a portable two-way communications device

A voltage controlled oscillator module (100) (400) provides tuning capability for the VCO in a shielded environment. The module includes a trimmable capacitor (110) (410) having metal plates (112, 114), (412, 414, 416) capacitively coupled through the substrate. One of the metal plates (114) (416) is a trimmable plate which can be trimmed to tune the VCO frequency. The trimmable metal plate (114) (416) remains exposed on the bottom surface (108) (408) of the substrate (104) (404) so that the frequency of the VCO can be tuned while the reminder of the oscillator circuitry (102) (402) on the top surface (106) (406) is encapsulated by a ground shield (116) (418).

Shielded VCO module having trimmable capacitor plate external to shield

A voltage controlled oscillator module assembly (300) minimizes microphonics in a low profile package. Included within the module (300) are a substrate (302), VCO circuitry (308), and a ground shield (314) encapsulating the VCO circuitry. Included within the VCO circuitry (308) is at least one resonator (310) which is solderable on at least two of its surfaces. One surface of the resonator (310) is soldered to the substrate (302) while another surface of the resonator is soldered to the shield (314). An improved ground is thus provided to the resonator (310) which reduces the occurrences of microphonics while providing a low profile package for the module (300).

A low-profile, high density, electrical connector (10), includes multiple layers (19, 22) of substantially parallel electrical conductors (31), the electrical conductors (25) each having a planar portion (29), and spaced ends (31) angling away from the planar portions (29). The planar portions (29) of the electrical conductors (25) are insulated with an insulating material (34). The spaced ends (31) of the electrical conductors (25) on each layer form a row of connector pins (13, 16). The connector (10) is formed by attaching the multiple layers (19, 22) along the insulated planar portions (29) of the conductors (25) to form a substantially rigid, low profile, multilayered structure.
