This invention relates to improvements in slotted cable antenna structures. This slotted cable antenna is built on a length of standard semi-rigid rf transmission line having a number of slots (gaps) cut in its outer conductor. Associated with each slot is a shunt conductor, the length of which is adjusted to control the amount of rf energy which escapes through that slot. Between each slot, the semi-rigid line is bend into a meander (loop) to introduce controlled delay in the radiated rf energy from the following slot. The meander is by-passed with a solder connection to maintain continuity of antenna current with the chosen physical slot spacing, typically half-wavelength, approximately. An embodiment of this invention is useful as an element in frangible antenna arrays such as employed in UHF glide slope stations of the Instrument Landing System (ILS). |
