Solution Overview
Problem
Conventional multi-band antennas are large and bulky, limiting their application in various settings due to their inability to provide multiple services simultaneously.
Innovation Solution
A compact antenna assembly with a curved printed circuit board (PCB) and multiple antenna structures configured to provide directional radiation in multiple frequency bands, allowing for simultaneous operation across different frequency ranges, such as cellular, LTE, ISM, and GPS bands, while being adaptable to curved surfaces like fire hydrants or light poles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multi-band antennas are used to provide multiple services, then multiple frequency bands can be supported, but the antenna becomes large and bulky
Solution Approach 1:
The antenna is divided into multiple independent antenna elements (first antenna, second antenna, third antenna, fourth antenna) that can be independently configured for different frequency bands. Each antenna element can be selectively activated based on the required service, allowing multi-band operation without requiring a single large antenna structure.
Solution Approach 2:
The patent transitions from conventional planar antenna arrangements to a three-dimensional spatial configuration where antenna elements are positioned at different locations and orientations. This includes mounting antennas on vertical surfaces, curved surfaces, and using various polarization orientations to achieve multi-band coverage in a compact footprint.
2Device complexity
If a single antenna is used for multi-band operation, then device complexity is reduced, but the antenna becomes large and bulky
Solution Approach 1:
Instead of using a single complex multi-band antenna, the system segments the antenna function into multiple simpler antenna elements. Each element is optimized for specific frequency bands, reducing the complexity of individual antenna designs while achieving overall multi-band capability through selective activation of different elements based on service requirements.

AI summary
A nozzle cap assembly can include a nozzle cap body defining a top end and a bottom end, the nozzle cap body defining a base positioned at the top end and a curved side wall extend from the base down to the bottom end; an enclosure coupled to the top end, the enclosure rotationally fixed relative to the nozzle cap body, the enclosure at least partially defining an enclosure cavity; and a nut base positioned opposite from the nozzle cap body, the enclosure positioned between the nut base and the base.
