Spiral Antenna Cuts Low Profile To 9.4 GHz | Microwaves ... As indicated by Fig. 2, it is reasonable to feed the antenna with a 10-mm-long ETMB; the plot of S 11 for the integrated model in Fig. 6(a) shows that S 11 s below -10 dB from 0.8 to 8.6 GHz. 6. These simulations show the results for the integrated model of the antenna and balun (a) and the reflection coefficient (b) radiation pattern at 0.8 ...
COPLANAR WAVEGUIDE-FED PLANAR SPIRAL ANTENNA WITH ...
This work covers the design and experiment of a finite-ground stripline-based spiral antenna with a Dyson-style balun and feed network (including broadband impedance transformer) that have been integrated into a multi-layer (via-free) structure. The spiral antenna uses the finite grounds of the stripline feed network (including the balun and impedance transformer) as one arm of the spiral, and ...

IET Digital Library: Low-profile broadband dual-mode four-arm slot spiral antenna with dual Dyson balun feed The authors propose a low profile 4-arm slot spiral for broadband commercial applications. The antenna is designed for circularly polarised dual-mode, 1st (normal) mode and 2nd (split-beam) mode, operation from 1.4–3.5 GHz and 2.5–6 GHz, respectively. Phase progressions at arm ports are realised through the odd and even coplanar waveguide (CPW) excitations, a dual Dyson balun, and a single A BROADBAND VHF-L BAND CAVITY-BACKED SLOT SPIRAL …
