Background:
A client from Saudi Arabia approached RF Element with a need for a dual-port, dual-polarized feedhorn antenna that could cover a broad spectrum, including 4G/5G bands (1700-3800MHz) and the 900MHz frequency. They wanted this antenna to be compatible with a 60cm diameter parabolic dish, aiming for the highest gain possible. Our engineers saw the task of creating a 3G 4G 5G MIMO feedhorn antenna with such a wide operational range as a notable challenge.
Challenges:
The objective was to engineer an antenna that could adeptly cover the 900MHz GSM band, 1700-2700MHz for 4G LTE, and the 5G spectrum of 3200-3800MHz. It was crucial to achieve this without a drop in gain or an increase in VSWR, a tall order in the antenna design world.
RF element's Solution:
Our engineering team took a creative and methodical approach to address these challenges:
1. Antenna Array Design: After numerous simulations, we developed a specialized antenna array that covers the 1700-3800MHz range. It's designed to fit existing feedhorn antenna housings, keeping redesign costs down and ensuring it works with parabolic dishes.
2. 900MHz Frequency Support: To make sure the antenna could also operate at the 900MHz frequency, we made adjustments to how the antenna array is mounted. This allowed us to maintain a VSWR of less than 1.8 at 900MHz, ensuring efficient performance.
3. Gain Optimization: We put a lot of effort into maximizing gain across the entire frequency range. This was achieved by choosing the right materials and fine-tuning the antenna's size and radiation pattern to perfection.
Performance Testing and Iterations:
Our engineers performed thorough performance testing and made several design iterations to perfect the antenna's performance. This meticulous process made sure the final product met and even surpassed the client's expectations.
Final Product:
Our efforts led to the development of a 3G 4G 5G MIMO feedhorn antenna that met the client's performance criteria and was successfully deployed in Saudi Arabia. Below is a visual representation of our 4G/5G MIMO feedhorn antenna. Please note that the image provided is of an initial version, intended for case analysis and studies.
