Double-ring wideband patch antennas

Microwave and Optical Technology Letters, 1998
The singleand double-shorted ring antennas with electromagnetic coupling to the feed line are presented. Their wideband and easy matching characteristics will be discussed, and a possible design criterion will be outlined. Experimental results, demonstrating the effecti eness of the large frequency band beha ior, for the input parameters and the ...

Wideband Dual-Polarized Patch Antenna

2006 10th IEEE Singapore International Conference on Communication Systems, 2006
Dual-polarized L-probe patch antennas afford wide impedance bandwidth and increased channel capacity. However, due to the close proximity, the coupling between the two input ports remains an important problem. In this paper, we introduce the use of a novel 180deg broadband microstrip balun which delivers both balanced power splitting and consistent ...

Novel wideband circular patch antenna

2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2016
In order to overcome the narrow bandwidth of the ordinary patch antennas, a novel configuration of patch antenna which can widen the bandwidth of patch antenna significantly is discussed in this paper. In terms of the analytical results based on the equivalent circuit method and the HFSS software, a rule derived from the simulation results that can ...

Wideband Multimode Filtering Circular Patch Antenna

IEEE Transactions on Antennas and Propagation, 2021
A wideband circular patch antenna (CPA) is proposed and fabricated in this article. Based on the cavity mode theory of circular patch, four resonant modes of quasi-TM01, quasi-TM02, quasi-TM03, and quasi-TM04 are merged together to obtain a wide passband through cutting slots and adding short pins on the driven patch.

A wideband circular patch antenna

Microwave and Optical Technology Letters, 2000
A new design of a circular patch antenna with an impedance bandwidth greater than 25% and a peak antenna gain about 8.3 dBi is presented. The circular patch antenna has a thick air substrate, and a pair of wide slits are cut in the circular patch to facilitate the antenna's impedance matching. The circular patch is supported by a conducting post, which

Wideband patch antennas for mobile communications

AEU - International Journal of Electronics and Communications, 2006
Abstract This paper describes a new technique for bandwidth enhancement of microstrip patch antennas. An electromagnetically coupled (EMC) feeding structure was employed to increase the bandwidth. L-strip feeding rectangular and triangular patches were simulated and tested.

Wideband Monopolar Square-Ring Patch Antenna

IEEE Transactions on Antennas and Propagation, 2006
The design of a monopolar square-ring patch antenna with wideband operation is presented. The antenna consists of a parasitic square-ring patch antenna that is shorted to the ground plane through two shorting walls and is excited by a top-loaded coaxial probe.

Ultra-wideband circularly-polarized patch antenna

2006 Asia-Pacific Microwave Conference, 2006
An ultra-wideband circularly-polarized (CP) microstrip antenna is presented with the introduction of one wideband 90deg feed network. The CP patch antenna experimentally offers a 10-dB impedance bandwidth of 71.7%, 3-dB axial-ratio bandwidth of 81.6% and a gain bandwidth of 52.2% with its highest gain of 8.1 dBi at 1.8 GHz.
