Custom 433MHz Antenna Solutions


Haitong vision is to be a global, world-class, trusted leader in antenna solutions that aims to deliver advanced technologies for the connected world. We provide one-stop solutions. Our expert team tests and checks our antennas in a production line to ensure that all products are working.

Process In Design And Production Stage For 433MHz Antenna

We provide various manufacturing process phone antenna options to meet the mechanical constraints of your application. We design and manufacture antennas that fulfill the most stringent operating requirements, and we pioneer unique embedded antenna systems.


Initial Dimensions

The 433MHz antenna design characteristics of a rectangular microstrip antenna are calculated. The transmission line model's initial antenna design is a rough estimate.

Design of Antennas

The printed circuit board was utilized to create the antenna prototype, whose design model was completed, and performance parameters were projected.


Obtain and High gain Evaluation

The gain and high gain efficiency numbers are given locally for a few frequencies. It's small because the dual-band capability enables two antennas to perform this purpose.
