Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power fed through the antenna feed is increased to increase emitted power, then the power output of the waveguide and overall system increases, but the system reaches the physical limit of the feed antenna, waveguide and horn antenna structure
Solution Approach 1:
The single feed antenna is segmented into multiple feed antennas (first feed antenna, second feed antenna, etc.) arranged in parallel within the waveguide. Each feed antenna has its own antenna feed connected to the horn structure, allowing the system to distribute and combine power from multiple independent sources to exceed the physical limits of a single antenna while maintaining structural integrity.
2Power
If multiple resonators are integrated to increase power and range, then the power and effective range increase, but significant reconstruction of the waveguide and horn structure is required which is costly and time-consuming
Solution Approach 1:
The horn structure serves multiple functions simultaneously: it acts as the radiating element for multiple feed antennas in parallel, maintains the original geometric configuration for compatibility, and provides a unified output aperture. This multi-functionality allows integration of multiple resonators without requiring reconstruction of the horn structure itself, reducing complexity and cost.
Solution Approach 2:
Instead of adding multiple resonators in the traditional spatial arrangement that would require structural reconstruction, the invention places multiple feed antennas in parallel within the waveguide cross-section (utilizing the transverse dimension). This dimensional approach allows power multiplication while maintaining the original horn structure's longitudinal geometry.
3Power
If multiple antennas are integrated in series within the waveguide, then power and range are enhanced through synchronized operation, but the waveguide length must be adjusted
Solution Approach 1:
The waveguide length is adjusted as a controlled parameter change to accommodate the synchronized operation of multiple series-integrated antennas. By modifying the electrical length and physical dimensions of the waveguide, the system optimizes the phase relationships and impedance matching for multiple antennas operating in series, enabling enhanced power output while maintaining proper electromagnetic field distribution.

AI summary
A horn antenna for emitting an electromagnetic HPEM microwave pulse along a central axis contains a microwave generator for the pulse having a waveguide along the central axis with a generator opening for the pulse, and a horn structure for shaping the pulse with an input opening and an emission opening for the pulse. The generator contains at least one HPEM source for the pulse. Each HPEM source contains at least two antennas for pulse components, disposed in succession in parallel with the central axis. The pulse is formed as a sum of the pulse components. A method for reconstructing a horn antenna to form the horn antenna with increased power, includes constructively increasing a number of antennas toward a respective HPEM source and orienting remaining antennas in a row relative to the first antenna, increasing the waveguide length, and keeping other dimensions of the horn antenna unchanged.
