“…There are also some studies on deployable antennas; in [ 25 ], a survey is performed on different types of antennas for CubeSats, and the equations and tools for the antenna design are provided. In addition, the design and testing on UHF [ 26 ] and VHF [ 27 , 28 ] antennas has been the object of research. In [ 29 ], there are also some large deployable antennas for CubeSats.…”

The 3Cat-4 mission aims at demonstrating the capabilities of a CubeSat to perform Earth Observation (EO) by integrating a combined GNSS-R and Microwave Radiometer payload into a 1-Unit CubeSat. One of the greatest challenges is the design of an antenna that respects the 1-Unit CubeSat envelope while operating at the different frequency bands: Global Positioning System (GPS) L1 and Galileo E1 band (1575 MHz), GPS L2 band (1227 MHz), and the microwave radiometry band (1400–1427 MHz). Moreover, it requires between 8 and 12 dB of directivity depending on the band whilst providing at least 10 dB of front-to-back lobe ratio in L1 and L2 GPS bands. After a trade-off analysis on the type of antenna that could be used, a helix antenna was found to be the most suitable option to comply with the requirements, since it can be stowed during launch and deployed once in orbit. This article presents the antenna design from a radiation performance point of view starting with a theoretical analysis, then presenting the numerical simulations, the measurements in an Engineering Model (EM), and finally the final design and performance of the Flight Model (FM).

“…The main specifications of a BGAN antenna are as follows: for an open-ended QHA, while λ/2 or λ configuration is often used for short-circuited QHA [8,10]. In either case, QHA radiation pattern is typically optimised and the design degrees of freedom include the winding pitch angle of the helix (determined by the antenna height and number of turns), the length of the radiators, and the diameter of the core.…”

“…Alternatively, resonant axial mode printed quadrifilar helical antennas (PQHAs) [8,9] are particularly attractive for GPS/BGAN applications, as they offer small size, CP radiation, and wide-angle coverage in the elevation plane. Each PQHA is composed of four equi-spaced parallel line radiators with an optimised pitch angle that are wound in a clockwise or counter-clockwise manner depending on the polarisation sense/lobe direction required.…”

A novel electronically steerable phased array antenna is developed for global positioning system/broadband global area network (GPS/BGAN) navigation applications. The array is composed of 2 × 2 printed quadrifilar helical antennas (PQHAs) integrated with digital phase shifters for beam steering over the transmit/receive bands. The feed network of each PQHA is based on a sequential rotation to achieve wideband circular polarisation (CP). An elegant control network with the embedded microcontroller is designed to provide driving bits to the phase shifters with reduced phase error. The meandered line design maintains high‐performance CP radiation up to ±60° off‐axis, within 1525 to 1660 MHz, and its size is 44% of the design with straight lines. The array gain is positive over 1450–1800 MHz beyond the BGAN band, with better than 13 dB return loss and <2.2 dB axial ratio. The measured broadside gain of the array exceeds 8.5 dBi at 1600 MHz, and has a wide beam steering of ∼±80° over the BGAN band. The developed antenna represents a significant technical advance to the design and manufacturing of PQHA array, it has a compact size, low cost and lightweight with a relatively large bandwidth and almost hemispherical coverage with excellent right‐hand circularly polarized radiation.

Return loss under 6dB, SWR less than 3, Gain between 5.9 to 6.6dBi, Bandwidth of 130MHz and Omni directional radiation pattern is obtained in (Takacs et al, 2015). In this paper polarization reconfiguration is obtained using square shaped antenna and PIN diode for switching purpose.…”

In wireless communication, the high performance handsets are blooming in the market. Multiple applications are incorporated in these portable devices. In this regard, antenna plays a very important role in handling these multiple functions simultaneously. Radiation pattern is one of the important parameter of antenna. This paper presents, radiation pattern of a compact reconfigurable meander micro strip patch antenna, suitable for portable devices. Here, effect of cover on radiation pattern is also displayed. The reconfigurable antenna radiation pattern also compared with the traditional antenna radiation pattern for conclusion. The antenna is designed and tested at 2.4GHz (ISM band) having 130MHz bandwidth. HFSS (High Frequency Structure Simulator) is used to design and simulate the antenna. Proposed antenna changes its polarization (horizontal/ vertical) as per necessity using PIN diodes. The radiation pattern is measured in the laboratory using antenna measurement system. The results focus on the fact that polarization reconfiguration is better performance than the frequency reconfiguration technique in antenna in portable device. RÉSUMÉ.
