A vehicle slot antenna wherein an electro-conductive coating is applied to the surface of a glass ply. The peripheral edge of the conductive coating is spaced from the vehicle window edge and connected to a high conductive bus bar to define an annular slot antenna with low resistance loss and improved antenna efficiency. The slot antenna is fed by a thin conductive line located in the middle of the slot and parallel to the bus bar. The thin line along with the conductive coating and window frame form a coplanar waveguide (CPW). The CPW feed provides a convenient feed for the antenna at any point around the perimeter of the window slot and affords antenna tuning and impedance matching. The antenna design can use the characteristic impedance of the CPW line to match the impedance of the slot antenna to the impedance of a coaxial cable or other input impedance.

The present invention discloses a portable personal communication device with an extendable helical antenna. This helical antenna is made of an elastic conductive spring, configured to change its height over a ground plane and along the antenna axis, mainly having two positions: a stowed position where the antenna is pressed down between the ground plane and a rigid cover, achieving a low profile; and an operational position where the rigid cover is removed and the antenna is extended by its own spring force, to a higher height, improving antenna gain. Normally, a second planar antenna may be placed over the same ground plane, not exceeding the footprint of the helical antenna, thus utilizing a compactly small volume and yet achieving a considerable electromagnetic decoupling between the antennas, due to their different radiation patterns. According to one embodiment, these antennas are installed in a Personal Locator Beacon (PLB) for Search and Rescue (SAR) of people in distress, where the planar antenna is coupled to a Global Navigation Satellite System (GNSS, such as GPS) receiver, and the helical antenna is coupled to a VHF/UHF radio.
