<p>The present invention relates to the field of antennas. Provided is a combined antenna, comprising a plurality of microstrip antennas which are located on a circuit board and comprise a first-layer microstrip antenna with a first radiation sheet, a second-layer microstrip antenna with a second radiation sheet, and third-layer microstrip antenna with a third radiation sheet in sequence from top to bottom, and a feed network and a shielding box being arranged below the circuit board, wherein the first-layer microstrip antenna is connected to the feed network through the second-layer microstrip antenna and the third-layer microstrip antenna by using a center feed needle, the second-layer microstrip antenna is connected to the feed network through the third-layer microstrip antenna in a double-fed needle mode, and the third-layer microstrip antenna is connected to the feed network in the double-fed needle mode. Further provided is a handheld antenna device. By adopting the above-mentioned technical solution, the loss can be reduced, so that this combined antenna has good vertex gain and low elevation gain.</p> |
