Abstract

The invention discloses an ultrashort wave and short wave multiplexing vehicle-mounted conformal antenna comprising a vehicle body (1), switch changeover feed sources (2), insulating support rods (3),folding metal rods (4), on / off selection switches (5) and a straight metal rod (6). The switch changeover feed sources (2) are fixed on the front upper part of the vehicle body (1). The on / off selection switches (5) are fixed on the rear upper part of the vehicle body (1). The folding metal rods (4) are conformal on the two sides of the vehicle body (1) in a bending way along the vehicle body (1)with the two ends connected with the switch changeover feed sources (2) and the on / off selection switches (5). The two ends of the straight metal rod (6) are connected with the left and right on / offselection switches (5). The folding metal rods (4) and the straight metal rod (6) are fixed on the vehicle body (1) through the insulating support rods (3). Ultrashort wave and short wave vehicle-mounted conformal antenna multiplexing can be realized by switching different states of the switch changeover feed sources (2) and the on / off selection switches (5) so that the communication vehicle passing capacity and concealment can be guaranteed and the antenna has the multipath communication function.

Description

technical field [0001] The invention relates to a vehicle-mounted antenna, in particular to a vehicle-mounted conformal antenna for multiplexing ultrashort wave and short wave. Background technique [0002] At present, ultrashort wave and short wave vehicle-mounted antennas are widely used in communication and military. The ultrashort wave or short wave vehicle conformal antenna is an improvement on the traditional whip antenna connected by a straight metal rod with an RF feed, which reduces the height of the vehicle antenna and improves the passing ability and concealment of the vehicle. In the September 2013 issue of "Military Communications Technology" "Simulation of Shortwave Vehicular Three-loop Antenna Performance" studied a shortwave vehicle conformal antenna. Its straight metal rod is placed vertically above the roof of the vehicle. Attach three folded metal bars parallel to the roof. The insulating strut is located between the vehicle body and the folding metal ro...
