SURFACE MOUNT TECHNOLOGY ANTENNA APPARATUS WITH TRIO LAND STRUCTURE

摘要

Disclosed herein is a surface mount antenna apparatus applied to a wireless terminal. The antenna apparatus includes a printed circuit board having a ground pattern, a land structure, and an antenna. The land structure includes a non-grounded area having no ground electrode, first and second land pads formed on opposite ends of the non-grounded area to be connected to ground electrodes, and an input pad formed between the first and second land pads and separated from them. The input pad is spaced apart from the first land pad by a preset interval. The antenna includes first and second ground electrodes formed on the lower surface of a dielectric block to be connected to the first and second land pads, a feeding electrode connected to the input pad, and a radiation electrode formed on some of the side surfaces and the upper surface of the dielectric block. The radiation electrode is connected to at least one of the first and second ground electrodes and the feeding electrode.
