Based on external aesthetics, external antennas have gradually been In addition, with the development of surface adhesion technology (Xie), crystal #antennas suitable for surface adhesion technology can significantly reduce the cost of packaging and connection. Design of Sky Shooting Fang Hong——. -The conventional chip antenna design is printed on the material chip. However, the Tao Wan material is not only expensive and fragile, and its relative dielectric constant is more than 7), which affects the antenna's bandwidth and Gain, relative product competition, etc. ID has dropped significantly. Due to the characteristics of low cost, strong and low relative dielectric constant (between i and 2), we use plastic chips instead of general-made chips to design low-cost and rugged chip antennas, and Dual-band operation, suitable for mobile communication systems with two different frequency bands. The antenna of the present invention is also suitable for surface adhesion technology. Compared with the ceramic chip antenna, the antenna is not only low-cost, sturdy, but also has better antenna bandwidth and gain. Therefore, the antenna of the present invention has extremely high commercial value.
