Abstract(E)	In this paper, we propose a vehicle antenna system on a conductive heat reflecting window. A slot antenna in a heatable vehicle glazing established between the heating bus bar, bus bar extension and the peripheral edge of an electrically conductive IR reflective coating. The antenna slot may be fed directly by a voltage source, a current source, or a coupled coplanar line at a position to excite both fundamental and higher order modes for multiband antenna applications. The slot antenna can be also established between split heating bus bars or heating bus bar extension to reduces heat loss and improve antenna efficiency. Multiple antennas can be integrated into the heatable glazing for multiband applications and/or diversity antenna systems. Results from simulation on the vehicle are compared with measurements.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
