Slot dipole antenna with single-and dual-band tuning characteristic
Jun 10, 2011 ... between the T-shaped feed line and the wide ground plane slot. ... plane for CP. In this paper, a dual frequency printed dipole-like antenna is.
Keywords— Compact antennas, Dual band antennas, Slot Antennas, Wireless applications, WLAN. 1. INTRODUCTION Many small antennas with broadband and multiband or ultra wideband performances including the dipole antenna, the monopole antenna, and planar antenna configurations reported [1-6]. These are printed antennas with moderate radiating characteristics and operates dual & multiple frequency bands. For the antenna fabrication and designed, the slot structures require providing a broadband ... Double Folded Multiband Slot Antenna with Dual E Stub – IJERT The dual notched frequency band operation was originated from the dual band resonance of two pairs of meta resonators which consist of two inner cell slot and two outer cell slot embedded in Unipolar symmetric dipole antenna [15].the fundamental system cavity mode is designed to resonate at 2.4GHZ and it is used in coverage area of 5GHZ WLAN band. The performance of antenna in terms of mutual coupling and envelope correlation have done [16] How does a slot antenna work? - Stack Exchange Babinet's principle, with some refinements from H.G. Booker, relate the slot antenna to a dipole. If, instead of a hole we have a conductor, and we make a very small cut in the center of this conductor so we can put a voltage source across it, we have a dipole. This dipole will be very similar to the slot, except: Broadband UHF Slot Antenna - Jampro Antennas Inc. The True and Tested PROSTAR broadband UHF slot antenna. Available for combined Analog & Digital applications. Also eliminates the need for multiple antennas.
A Slim Horizontally Polarized Omnidirectional Antenna Based on Turnstile Slot Dipole Cheng-Yuan Chin* and Christina F. Jou Abstract|A novel horizontally polarized (HP) antenna with omnidirectional pattern is presented in this paper. The proposed antenna applies the concept of rotating electric fleld method to conventional slot dipoles.
FM Dipoles UHF Circular Polarized Panels In addition to a standard portfolio of UHF, VHF and FM broadcast antennas, Mega Industries designs, builds and tests custom antennas from 50 MHz to 12 GHz in a variety of configurations including traveling wave, phased array and horn-fed reflectors. A SHALLOW-CAVITY UHF CROSSED-SLOT ANTENNA The shallow-cavity crossed-slot antenna is a UHF radiator designed primarily for use on a high-speed aircraft operating as the airborne terminal in a satellite-to-air communications link. The require- ments, design analysis and performance characteristics are de- scribed. The antenna's shallow profile makes it attractive either as US6414647B1 - Slender omni-directional, broad-band, high The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Feed line interference to the antenna can be eliminated by including a centrally located
