Analysis of a Compact Wideband Slotted Antenna for Ku Band Applications

Abstract

The design procedure and physical module of a compact wideband patch antenna for Ku band application are presented in this paper. Finite element method based on 3D electromagnetic field solver has been utilized for the designing and analyzing process of proposed microstrip line fed modified -shaped electrically small patch antenna. After successful completion of the design process through various simulations, the proposed antenna has been fabricated on printed circuit board (PCB) and its characteristics have been studied. The parameters of the proposed antenna prototype have been measured in standard far-field rectangular shape anechoic measurement compartment. It is apparent from the measured antenna parameters that the proposed antenna achieved almost stable variation of radiation pattern over the entire operational band with 1380 MHz of −10 dB return loss bandwidth. The maximum gain of 7.8 dBi and 89.97% average efficiency within the operating band from 17.15 GHz to 18.53 GHz ensure the suitability of the proposed antenna for Ku band applications.

A compact UWB patch antenna with defected ground for Ku/K band applications

“…We observe maximum peak gain for the proposed antenna as compared to the antennas reported in Table and also the maximum radiation efficiency except for the antenna reported in Ref. which is fractionally better.…”

“…Simulated and measured antenna gains are presented in inset of Figure and a maximum of 8.5 dBi gain is observed at 15.4 GHz (φ = 40° and θ = 50°).On perusal of Figure and Table , the peak gain observed for the proposed antenna is highest amongst the reported papers …”

Epsilon‐shaped circularly polarized strip and slot‐loaded ultra‐wideband antenna for Ku‐band and K‐band

“…To avoid integration of band notch techniques, researchers started exploring higher frequency band, that is, Ku‐band and K‐band where negligible commercial applications are available at present. In Reference , a compact wideband antenna for Ku‐band satellite communication applications was reported. Its operating band was enhanced by using four arcs and a square slot to use it for Ku‐band and K‐band satellite applications …”

Compact, high gain, linearly polarized diversity antenna for KU band applications

“…In the lower frequency band available bandwidth is also low hence Ku band antenna design will be given considerable attention in recent times for wide bandwidth application . Several antennas are proposed for satellite application operating at Ku band using techniques such as array, partial ground plane concept, slot technology, defected ground structures, parasitic element feed, and so on . A 10 × 8 multi beam dual‐band orthogonal linearly polarized antenna array operating at Ku‐band are presented for transreceiver applications.…”

“…The input impedance and symmetric radiation pattern are presented and examined. But the said antenna has comparatively low gain of . Defected ground structure technology is found to be useful to design single element antenna with wide impedance bandwidth ranging from 9.8 to 17.55 GHz that covers Ku‐band and partially X‐band.…”
